Claims

[Scope of claim for utility model registration] (1) A main body case and a mechanical case configured in the same manner as a normal watch, an alarm disk, a time disk, a place name ring, a minute hand and a mechanical case configured in the same way as a normal watch. It has a second hand, and the user's local time (one time zone in the world) as well as the 23rd hour on earth.
A world clock that displays the local time zone as well as alarm times for 23 other time zones as well as the local time zone. (2) Mark or print 12 city or place names at equal intervals along the inner and outer peripheries of the place name ring, making a total of 24 of the above city or place names for each of the 24 standard times on earth. In actual use, rotate the city name or place name (or the city name or place name within the same time zone) on the place name ring.
For example, if it is 10 a.m. in New York (representing the 75 degrees west longitude set on the outer circumference of the place name ring above), then the other 12 cities or regions west of New York will have one city or region with one city or region. (or approximately 15 in longitude)
degree intervals) in chronological order of Chicago (90 degrees W, 9 a.m.), Denver (105 degrees W, 8 a.m.), and so on to Nome (165 degrees W, 4 a.m.), and then the inner circumference of the above place name ring. Moving to the other side, the international date line (180 degrees west longitude or east longitude, 3 a.m.), Noumea (165 degrees east longitude, 2 a.m.), Sydney (150 degrees east longitude, 1 a.m.), etc.
The 11 other cities or place names east of New York (the 12th city is Singapore, which has already been selected) are spaced consecutively and evenly spaced up to Singapore (105 degrees east longitude, 10 a.m.). Buenos Aires (60 degrees west longitude, 1 a.m.)
1 o'clock), Rio de Janeiro (45 degrees west longitude, 1 a.m.)
2 o'clock) until Berlin (15 degrees west longitude, 4 p.m.), then move to the inner circumference of the above place name ring and similarly reach Cairo (30 degrees east longitude, 5 p.m.) and Riyadh (45 degrees east longitude, 6 p.m.). The world's 24 times, represented by the 24 largest cities or regions around the world, are located at continuous and evenly spaced locations such as Singapore (105 degrees east longitude, 10:00 p.m.) The world clock according to claim 1, which is sometimes given. 3. The world clock according to claim 1, wherein said place name ring is provided in the front plate of the main body shell, or in the back plate when said time disk and alarm disk are made of transparent material. (4) The world clock according to claim 1, wherein said alarm disk on which an alarm pointer is marked or printed is used instead of a conventional alarm pointer. (5) 12 index lines (or alarm lines)
are marked or printed at equal intervals along the outer periphery, and the alarm disc marked with the alarm line between the two index lines numbered 11 and 12 corresponds to standard time other than local time. For example, if the above index line, which is used as an alarm guide and is numbered 7, is set at Chicago, the difference between morning and afternoon can be determined by mental arithmetic, and 7 o'clock for Chicago and 6 o'clock for Denver. The world clock according to claim 1, wherein an alarm sound is sounded at a time such as . (6) A time disc with the above-mentioned hour hand marked or printed is used in place of the conventional hour hand, and the numbers 1 to 12 on the outer circumference of this time disc are equally spaced to indicate times other than local time. The world clock according to claim 1, which is marked or printed. (7) Reduce the 24 city or place names to 12 to make them easier to read (choose only one of the two locations 180 degrees apart in longitude) and mark or print the above time on the disk. Delete the place name ring above, and change the hour hand to the name of the city or place where the user is located (
mark or print an hour hand on said time disc so as to point to a region (or area within the same time zone);
3. The world clock for a wristwatch or small wristwatch according to claim 2, wherein when the user moves to another standard time zone, the position indicated by the hour hand is changed accordingly.
