[Prior Art] A world watch that can read the moments of the world's major cities is being developed. World clocks can be classified into 24-hour and 12-hour systems. The 24-hour world clock has a 24-hour hand that rotates once in 24 hours, and a ring that is recorded in the world's major city names. The number of city names recorded in the ring is adjusted so that the city name where the user stays is aligned at 24 o'clock, so that the user can know the local time of each city. However, in the world timepiece of the 24 o'clock system, the angle indicated by the 24 o'clock hand is different from the angle indicated by the needle of the normal timepiece, so that it is difficult for the user to easily grasp the time. The world watch of the 12 o'clock system is disclosed in Patent No. 3 2654 15 . As shown in Fig. 1, the world time clock 101 of the 12-hour system has a dial 103, an hour hand 105, a minute hand 107, and a longitude display unit 109. Fig. 1 is a view showing a problem of the prior art in which Fig. 1 of the above document is simplified. As shown in Fig. 2, the above member is surrounded by the outer frame 115, and the upper opening portion is covered with a transparent outer casing 117. The dial 103 is formed in a disk shape and has a peripheral portion in which numbers of 1 to 12 are drawn at equal angles. The hour hand 1 05 is rotated by one turn on the dial 10 3 for 12 hours by the drive motor 1 3 1 . The minute hand 107 is rotated by 1 -4 - (2) 1269128 turns on the dial 103 by the drive motor 133 for 60 minutes. The longitude display unit 1 〇 9 is composed of an outer layer 1 1 1 and an inner layer Π 3 which are formed in a ring shape, and has an inner peripheral surface which is rotatably contacted with the outer peripheral surface of the dial 1 0 3 . The longitude display unit 109 is rotated in conjunction with the hour hand 105 and the minute hand 107, and is rotated by one rotation on the outer circumference of the dial 103 by the drive motor 135 for 12 hours, and the hour hand 1 0 5 is often rotated while maintaining a constant positional relationship. . The degree of the east longitude is every 15°, from 0° to 180°, and is clockwise drawn on the outer edge portion of the outer layer 1 1 1 of the longitude display unit 109. In the outer layer 1 1 1 , the east longitude 重叠° overlaps with the east longitude of 180°. The degree of the west longitude is every 15 degrees, from 0 to 180, and the inverse clock is plotted on the inner edge of the inner layer 1 13 of the longitude display portion 109. In the inner layer 1 1 3, the west longitude 0° overlaps with the west longitude 180°. The inner layer 1 1 3 and the outer layer 1 can be combined with the reference line 123 of the inner layer 113 passing through 0° (and 180°) of the outer layer 111 in conformity with the reference line 1 2 1 of the outer layer 111 (and 180°). 1 1. In addition, the baseline 1 21, 1 23 corresponds to the Greenwich Meridian and date change line. The main city name of the world is recorded in the outer layer 1 1 1 or the inner layer 1 1 3 of the longitude display unit 1 0 9 and recorded in the longitude of the location of the city. The world timepiece 1 0 1 has the following problems. When reading the local time of a city located in the West (or East) from a city located in the East (or West), the user must use the baseline 1 2 1,1 2 3 as the boundary, from the outer layer 111 (or the inner layer U3) The inner layer 113 (or the outer layer ill) discontinuously shifts the read path. Therefore, it is necessary to apply the reference line 1 2 1,1 2 3 in a different color or different line width from other latitude lines, so that the reference line 1 2 1,1 2 3 can be seen from the plurality of latitude lines. . -5- (3) 1269128 The user can shift the read path with the reference line 1 2 1,1 23 as the clock and clock. That is, in the latitude display portion 1 〇 9, the user can cross the Greenwich meridian and the date change line in both directions. Therefore, it is prone to misunderstanding of the noon/noon and date of local time. When the user moves to another city, the hour hand 1 〇 5 and the minute hand 107 must be aligned with the local time, and the positional relationship between the hour hand 105 and the longitude display unit 109 is changed. Further, since the longitude display unit 109 is housed in the interior of the timepiece, it is necessary to provide an adjustment member for changing the positional relationship between the hour hand 1 〇 5 and the longitude display unit 109. However, the method of changing the positional relationship and the adjustment member are not disclosed in the above documents. SUMMARY OF THE INVENTION An object of the present invention is to provide a world timepiece that can easily read the time of the world's major cities or countries, noon/afternoon and date. In order to achieve the above object, the present invention provides a world timepiece having an hour hand, a minute hand, and a dial in a casing, and is characterized in that: a ring portion is provided on the outer casing so as to be located outside the dial And being rotatable independently of the rotation of the hour hand and the minute hand; and the display portion is provided on the surface of the ring portion and substantially spirally wound; and the display portion has a central portion with a mark indicating the world standard time. Further, a latitude is allocated from a region between the central portion and the end portion, and a symbol indicating a country name or a city name corresponding to the latitude is displayed in the region. -6 - (5) The base of the center of the 1269128 3, and rotates once in 60 seconds. The driving device rotates the hour hand 5, the minute hand 7 and the second hand 9. The drive is set to a known configuration such as a mechanical type or a quartz type, and thus a detailed description thereof will be omitted. The outer casing 1 1 houses the dial 3, the hour hand 5' minute hand 7, the second hand 9 and the moving device. The outer casing 1 1 is composed of a first torso 33, a fixed body 33, a second torso 35, a back cover 37, a first pad 39 and a second pad 41. The first trunk 31 is a side surface portion constituting the outer casing 11. The fixed ring 33 is provided on the upper portion of the first trunk 31. Further, the fixing ring 33 is also formed integrally with the first torso 31. The dial 3 is sandwiched between the first body 31 and the fixed ring 33. The second torso 35 is provided at a lower portion of the first torso. The back cover 31 is connected to the inner peripheral surface of the second body 35 by the first spacers 39, and constitutes the bottom surface portion of the casing 11. The surface cover 13 is composed of a disk-shaped transparent member and has a peripheral portion that is lowered downward toward the central portion. The surface cover 13 is provided on the upper portion of the fixing ring 33 by the second pad 41, and closes the opening of the casing 11. Further, the surface cover 13 and the dial 3 are coaxial with each other. The cap head 15 is provided on the side of the outer casing 1丨. The user can operate the hour hand 5 and the minute hand 7 from the outside of the casing 1 by the cap 15. Since the cap head 15 is a known configuration, detailed description thereof will be omitted. The rotating ring 17 is an inner portion which is lowered downward toward the outer peripheral portion. The rotating ring 17 is disposed on the upper surface of the fixed ring 33 and on the peripheral portion of the surface cover j 3 . The leaf spring 43 is disposed between the rotating ring 17 and the stationary ring. The rotating ring 17 is fixed by the leaf spring 4 3 in the axial center of the dial 3, and the inner ring is 3 3 (6) (6) 1269128 center, right The retaining ring 3 3 is rotated in the clock direction and/or in the counterclockwise direction. The timepiece ring 19 is provided on the inner peripheral portion of the rotating ring 17 and rotates integrally with the rotating ring 17. The timepiece ring 19 is coupled to the rotating ring 17 by an adhesive member such as a double-sided tape. The rotating ring 17 and the clock ring 19 are coaxial with each other. Further, the rotation of the rotating ring 17 and the clock ring 19 is independent of the rotation of the hour hand 5, the minute hand 7 and the second hand 9. The uneven portion 2 1 is formed on the outer peripheral surface of the rotating ring 17 . When the user pinches the rotating ring 17 , the uneven portion 2 1 is responsible for the anti-slip function. As shown in Fig. 5A, the display portion 23 is a belt-like member which is spirally wound around the surface of the timepiece ring 19 by about two turns, and rotates integrally with the timepiece ring 19. The display unit 23 has front ends 25a and 25b, an inner middle portion 25C, an outer middle portion 25d, and a joint portion 25C. At the inner edge portion of the timepiece ring 19, the display portion 23 is wound from the front end 25a to the inner side intermediate portion 2 5 c, and is wound counterclockwise on the same circumference. The inner middle portion 25c is shifted by 18 from the front end 25a clockwise. At the outer edge portion of the timepiece ring 19, the display portion 23 is from the outer intermediate portion 25d to the front end 25b, and the clockwise winding is on the same circumference. The outer middle portion 25d is offset from the front end 25b by 12° counterclockwise. Further, the outer middle portion 25d is shifted clockwise by 6 from the front end 25a. The inner middle portion 25c is not offset from the front end 25b, but is located on the same line as the front end 2 5 b in the radial direction of the timepiece ring 19. The connecting portion 25e is formed in a straight line to connect the inner intermediate portion 25c to the outer middle portion 2 5 d. Next, a method of assigning the world's main city name (or main country name) to the display unit 23 will be described. -9- (7) (7) 1269128 As shown in Fig. 5B, the first imaginary line 27a is set to a position shifted by 6 from the inner middle portion 25c clockwise. The second imaginary line 27b is set to a position shifted by 6 from the front end 25a by a clock. The third imaginary line 27c is set to a position shifted by 6 from the front end 25b clockwise. The fourth imaginary line 27d is a position shifted by 12 from the outer middle portion 25d counterclockwise. The world standard time is set in the first imaginary line 27a. The east longitude is designated in the inner region from the first imaginary line 27a to the second imaginary line 27b. Specifically, the east longitude 165° and the 165° are respectively assigned to the first imaginary line 27a and the second imaginary line 27b. Then, in the inner region, as n° (0S nS 3 3 0) is increased clockwise from the first imaginary line 27a, only n/2° is increased from the east longitude. The west longitude is designated as an outer region from the third imaginary line 27c to the fourth imaginary line 27d. Specifically, the west longitudes 15° and 180° are assigned to the fourth imaginary line 27d and the third imaginary line 27c, respectively. Then, in the outer region, as the clock is increased from the fourth imaginary line 27d by only 3 3 0), m /2 is added from the west through 15 degrees. After the longitude is assigned to the display unit 23, the world's main city name (or major country name) is the position recorded in the longitude at which the city (or country) is assigned. Further, the Greenwich meridian and the date change line correspond to the first imaginary line 27a and the third imaginary line 27c, respectively. This embodiment is in the inner region, corresponding to east longitude, 1 5 °, 30 〇, 45. , 60〇, 75°, 90〇, 105°, 120°, 135°, 150〇 are recorded in Greenwich (GMT), Paris (PAR), Cairo (CAI), Moscow (MOW), Dubai ( DXB), Karachi (KH1), Dhaka (DAC), Bangkok (BKK), Hong Kong (HKG), Tokyo (TYO), Sydney (SYD) City-10- (8) 1269128. In addition, in the outer region, the positions corresponding to 45°, 60°, 75°, 90°, 105°, 120°, 135°, and 150° are recorded in Rio de Janeiro (RIO), Gallas (CCS). , New York (NYC), Mexico City (MEX) 'Denver (DEN), Los Angeles (LAX), Anchorage (ANC), Honolulu (HNL) city name. Next, the method of using the world clock 1 will be described. First, I imagined that the user who stayed in Tokyo read the local time in Paris from World Watch 1. As shown in Fig. 3, when the local time in Tokyo is 10:8:42, the user rotates the rotating ring 17, and the TYO is aligned at 10 o'clock. At this point, PAR will be aligned at 2 o'clock, so the local time in Paris is 2:8:42. Next, in order to read the noon/afternoon of Paris, the user searches the display unit 23 against the clock from TY0 to PAR. Therefore, the local time in Paris is 2:8:42. The second time, I imagined that the user who stayed in Tokyo sold the local time of Honolulu from World Watch 1. As shown in Figure 3, when the local time in Tokyo is 1 minute and 8 minutes and 42 seconds, the user will rotate the rotating ring 7' to align the TYO to the 1 point. At this point, HNL will be aligned at 3 o'clock, so the local time in Honolulu is 3:8:42. Next, in order to read the noon/afternoon of Honolulu, the user searches the display unit 23 against the clock from TYO to HNL. At this moment, the local time in Honolulu is 3:8:42 in the afternoon of the previous day due to the position of 12 | -11 - (9) (9) 1269128 3rd, Imagine that the user who stayed in Paris read the local time in Tokyo from World Watch 1. As shown in Figure 6, when the local time in Paris is 10:8:42, the user will rotate the rotating ring 17 to align the PAR to the 1 point. At this moment, ΤΥ0 will be aligned at 6 o'clock, so the local time in Tokyo is 6:8:42. Next, in order to read the noon/afternoon of Tokyo, the user goes from the PAR to the TYO and follows the display unit 23 clockwise. At this moment, the local time in Tokyo is 6:8:42 in the afternoon due to the position of 12 o'clock. Fourth, Imagine that the user who stayed in Honolulu read the local time in Tokyo from World Watch 1. As shown in Figure 7, when the local time of Honolulu is displayed at 10:8:42, the user will rotate the rotating ring 17 to align the HNL to the 10 o'clock position. At this moment, since the TYO will be aligned at 5 o'clock, the local time in Tokyo is 5:8:42. Next, in order to read the noon/afternoon in Tokyo, the user goes from HNL to TYO and follows the display unit 23 clockwise. At this moment, since the position of 12 o'clock is passed twice, the local time in Tokyo is 5:8:42 on the next day. World Watch 1 has the second feature. The display portion 23 is a strip-shaped member that is wound about two turns in a spiral shape. Therefore, even if the local time of the city located in the west longitude (or east longitude) is read from the city located in the east longitude (or the west longitude), the user can go from the inner edge portion (or the outer edge portion) of the display portion 93 to the outside. The rim (or inner edge 5D) simply shifts the read path' and can reduce misreading of the noon/afternoon local time. The front end 25a and the front end 25b of the display unit 23 are not directly connected. -12- (10) 1269128 That is, in the urban display unit 23, the user cannot cross the line. Therefore, misinterpretation of the date of the local time can be reduced. The user can easily read the noon/afternoon between the two points as long as they remember the next three points. That is, the time is traced back to the display unit 23 in the reverse clock; when the display unit 23 is chased clockwise, the time is advanced; and at the position of 12:00, the noon/afternoon is reversed. Since the timepiece ring 19 is disposed outside the outer casing 3, the clock ring 1 can be rotated by hand, thereby independently changing the position of the hour hand 5 and the display portion 23 independently of the rotation of the hour hand 5 and the minute hand 9, and it is not necessary to set The adjustment member for changing the positional relationship can reduce the manufacturing cost. Further, various modifications may be made without departing from the spirit and scope of the invention. For example, the timepiece ring 17 may be omitted, and the portion 23 may be provided on the surface of the rotating ring 21. (Second Embodiment) As shown in Figs. 8 to 10C, the arrangement of the timepiece ring portion of the world timepiece 51 is different from that of the world timepiece 1. Further, in the world timepiece 5, the same members as those of the world timepiece 1 are given the same reference numerals as shown in Figs. 8 and 9, and the world timepiece 51 has a dial 35, a minute hand 7, a second hand 9, and a driving device (not shown). The outer casing 1 1' cover 13 ^ cap 15 , the display portion 23 , the timepiece ring 53 , and the operation portion housing 1 〆 are the dial 3, the hour hand 5, the minute hand 7, the second hand moving device, the display portion 23 and the clock ring 5 3 is contained inside. When the external f period is changed locally, the return is passed through the user 7 or seconds. The current process configuration will display and display 1 in the middle, 〇, hour hand, surface 57 〇9, drive t 11' is -13- (11) (11) 1269128 from the first torso 31, the fixed ring 33', the second torso 35. The back cover 37 is composed of a first backing 39 and a second spacer 41'. The first torso 31 is a side surface portion constituting the outer casing 1Γ. The fixing ring 33· is provided on the upper portion of the first trunk 31. Further, the fixing ring 33 may be formed integrally with the first torso 31. The second trunk 35 is disposed at a lower portion of the first trunk 31. The back cover 31 is formed on the inner peripheral surface of the second torso 35 by the first spacer 39, and constitutes the bottom surface portion of the outer casing 1. As shown in Figs. 10A to 10C, the timepiece ring 53 has a base portion 53a, a first convex portion 53b and a second convex portion 53c. The base portion 53a is a circular display surface 55 having a tapered shape thereon. The first convex portion 53b is integrally provided on the outer peripheral surface of the base portion 539a, and is rotatably held between the first trunk portion 3 1 and the fixed ring 33'. The second convex portion 53c is integrally provided on the bottom surface of the base portion 53a, and is inserted into a concave portion formed on the inner peripheral edge side of the upper surface of the first trunk 31. A gear 61 is provided on the bottom surface of the second convex portion 53c. The dial 3 is sandwiched between the base portion 536a and the first torso 31. The surface cover 13' is composed of a disk-shaped transparent member. The surface cover 13' is connected to the inner peripheral surface of the fixed ring 3''''''''''' Further, the surface cover 13' and the dial 3 are coaxial with each other. As shown in Fig. 9, the operation unit 57 is a front end portion provided on the side surface of the outer casing 1 and having a hole formed in the first trunk 3 1 a. The rack 59 is a toothed end 6 that is provided at the front end portion of the operation portion 57 and that is engaged with the timepiece ring 53. The user can rotate the clock ring 5 3 - 14 - (12) (12) 1269128 from the outside of the casing 1 by the operation portion 57. As shown in FIG. 10A, the display portion 23 is displayed on the clock ring 53. The face 5 5 is spirally wound about 2 turns of the band member and rotates integrally with the watch ring 53. World Watch 5 1 has the second feature. Since the timepiece ring 53 is rotatably connected to the operation unit 57, the user can change the positional relationship between the hour hand 5 and the display unit 23 independently of the rotation of the hour hand 5, the minute hand 7 or the second hand 9 by the rotation operation portion 57. (Third Embodiment) As shown in Figs. 11 and 12, the world timepiece 171 has a shape different from that of the world timepiece 1. Further, in the world timepiece 71, the same members as those of the world timepiece 1 are denoted by the same reference numerals. As shown in Fig. 12, the display portion 73 is a belt-like member which is spirally wound around the surface of the timepiece ring 19 by about four turns, and rotates integrally with the timepiece ring 19. Both end portions of the display portion 73 are formed to have a narrower width as they approach the front ends 75a, 75b. The front end 75a is clocked by 9 〇 from the front end 75b. The first imaginary line 77a is a shaft center 连结 connecting the front end 75a and the timepiece ring 19. The second imaginary line 77b is a shaft center 连结 connecting the front end 75b and the timepiece ring 19. The third imaginary line 77c is shifted clockwise by 30 from the first imaginary line 77a. The fourth imaginary line 77d is offset from the second imaginary line 77b by 30° counterclockwise. The display unit 73 has an inner layer 73a, a middle layer 73b, and an outer layer 73c in a region divided by the first imaginary line 77a and the second imaginary line 77b. Next, a method of assigning the world's main city name (or main country name) to the display unit 713 will be described. -15- (13) (13) 1269128 The world standard time is the fourth imaginary line 77d set in the middle layer 73b. The east longitude is an inner region designated from the fourth imaginary line 77d of the middle layer 73b to the third imaginary line 77c of the inner layer 73a. Specifically, the east longitude 0° to 165° is the third imaginary line 77d and the third imaginary line 77c which are respectively assigned to the fourth imaginary line 77d of the middle layer 73b and the inner layer 73a. Then, in the inner region, as the fourth imaginary line 77d from the middle layer 7 3b is clockwise increased by η° (0$ 3 3 0), only n/2° is increased from 0° east longitude. The west longitude is an outer region designated from the fourth imaginary line 77d of the middle layer 73b to the fourth imaginary line 77d of the outer layer 73c. Specifically, the west longitudes 0° and 180° are the fourth imaginary line 77d and the fourth imaginary line 77d which are respectively assigned to the fourth imaginary line 77d of the middle layer 73b and the outer layer 73c. Then, in the outer region, as the fourth imaginary line 77d from the middle layer 73b is only increased by m° (0 S mg 3 60) counterclockwise, it is increased by only m/2 from the west through 0°. After the display unit 73 assigns the longitude, the world's main city name (or main country name) is the position recorded in the longitude of the location in which the city (or country) is assigned. Further, the Greenwich meridian and the date change line are the fourth imaginary line 77d corresponding to the fourth imaginary line 77d of the middle layer 73b and the outer layer 73c. Further, the method of using the world timepiece 71 is the same as the method of using the world timepiece 1. The world timepiece 71 has a second feature in addition to the features of the world watch 1. The display portion 713 is smoothly connected to the display portion 23, and the inner region and the outer region are smoothly connected. Therefore, even if the local time of the city located in the west longitude (or east longitude) is read from the city located in the east longitude (or west longitude), the user can still go from the inner region (or the outer region) of the display portion 23 to the outer side-16 - (14) (14) 1269128 Area (or inner area) to move the read path more easily. (Fourth Embodiment) As shown in Figs. 13 and 14, the world timepiece 81 is such that the city display unit 73 is disposed on the display surface 55 of the timepiece ring 53 of the world timepiece 51. Further, in the world timepiece 8 1 , the same components as those of the world timepieces 5 1, 7 1 are given the same component symbols.
