  • This invention relates to a world timepiece adapted to indicate digitally the local time as well as the home-base time and to be easily adjustable when entering a new time zone without disturbing the home-base time reading.
  • a movable bezel on which is printed the localities or the names of principal cities in the local time zone, is mounted on the periphery of the glass. These are usually expensive to manufacture, and have an undesirable appearance.
  • the equation between the new local time and the home-base time must be read on the movable bezel and said bezel must be adjusted.
  • the movable bezel Every time the wearer enters another new time zone, the movable bezel must be adjusted and reset in this manner. This arrangement is extremely complicated and troublesome.
  • the other type of conventional world timepiece is the Greenwich mean time (GMT) timepiece which has a GMT hand which makes a full rotation for each 24 hours.
  • the GMT hand is positively geared to the standard minute and hour hand of the watch, the several hands moving correspondingly when the watch is manually set. Accordingly, when entering a new time zone, the GMT hand must also be shifted.
  • the movable bezel must be shifted to establish the proper time displacement between local time and GMT after the wearer resets local time.
  • the main object of this invention is to provide a new world timepiece simplified in arrangement and manufactured at reduced cost.
  • the world timepiece in accordance with the invention includes a 24 hours indicating wheel interlockingly driven with the watch movement and a locative rim indicating local time zones. Means is provided for adjusting the setting position of said 24 hours wheel interlockingly with said locative rim and for independently adjusting said 24 hours indicating wheel.

  • the internal part of said rim 25 is bent in an L-shaped under 24 hours indicating wheel 22.
  • An internal gear is formed on the inner periphery of rim 25 below, said 24 hours indicating wheel having 24 teeth 25b at regular intervals each of which has a rectangular wall 25c and an inclined wall 25d.
  • said rim 25 together with said hour wheel I3, said minute wheel pinion 120, said intermediate wheel 14 and said driving disk I5 are rotatably mounted on plate G, said parts being covered with a locative rim guard 26.
  • Intermediate lever 27 having two arms projecting in a different direction is rotatably mounted by an axle 28 fitted in plate G.
  • One of said arms of intermediate lever 27 is positioned to engage each tooth 25b of said locative rim 25 as said rib is rotated in the counterclockwise direction to the position shown by phantom lines in FIG. I.
  • the other of said arms engages with an arm 30a of local time corrector 30 which is rotatably mounted on an axle 26 fitted in the plate G. to drive the local time corrector in the clockwise direction as viewed in FIG. I.
  • the local time corrector 30 is engaged by a U-shaped local time corrector spring 3
  • a corrector finger axle 32 is mounted on said local time corrector for supporting the end of a local time corrector finger 33 formed as a long and slender leaf spring.
  • local time corrector 30 is formed with a second arm 30b having at its end a projecting part 30c which projects at an angle of about from arm 30a.
  • the free end of finger 33 engages the side wall of the recea formed in projecting part 30c.
  • the end of said finger 33 stretches over arm 30b to push a tooth 21a of the wheel 2 I.
  • Said local time corrector is also formed with an arm 30d, which is on the opposite side thereof relative to first-men tioned arm 30a.
  • Arm 30d is aligned to turn local time corrector 30 about a fixed angle in the clockwise direction as shown by phantom lines in FIG. I against the pressure of spring 31, when arm 30d is pressed by a conventional setting lever such as setting lever 35 pivoted on axle 34 as shown in FIGS. I and 3.
  • a returning spring 37 is operatively cou led to setting lever 35.
  • a flexible Iocative rim jumper 38 is positioned adjacent locative rim 25 with a projecting part 380 thereof nonnally pressed against the root between adjacent teeth 25b of rim 25 as shown by full lines in FIG. I.
  • a clutch wheel 39 of conventional shape is mounted on the square portion of a winding stem 36.
  • the clutch wheel is displaceable on said winding stem in three steps indicated in FlG. l as a, b and c; said displacement being in response to the longitudinal displacement of said winding stem.
  • the world timepiece according to the invention having a conventional cannon pinion ll driven by the usual watch movement (not shown), operates as follows.
  • the minute and hour hands of the normal time indicating system are operated by an hour wheel 13 through a cannon pinion II, a minute wheel 12 and a minute wheel pinion 12a.
  • said cannon pinion l 1 turns driving disk 15 one full revolution in the clockwise direction as viewed in FIG. 1 through an intermediate wheel 14, which engages pinion ll, and a driving disk pinion 15a.
  • the end of a local time finger l8 fixed on disk 15 catches and kicks away a tooth 21a of star wheel 21 in the counterclockwise direction once each hour. in this manner, 24 hours indicating wheel 22, joined with star wheel 21, advances the angle represented by one of the digits printed on said wheel 22.
  • expected time zones can be indicated in the expected position. Since 24 hours indicating wheel 22 is aligned with the locative rim, digits indicating the local time can be coordinated with the localities in the local time zone.
  • winding stem 36 When only digits indicating the local time printed on the locative rim must be shifted, winding stem 36 must be pushed into the first stage to place clutch wheel 39 in the position b (solid lines) of FIG. 1. In this stage the rotation of the winding stem is not transmitted.
  • setting lever 35 When the winding stem is pushed further, setting lever 35 is rotated in the counterclockwise direction as viewed in FIG. 1 around an axle 34, against the pressure of a returning spring 37. Said setting lever 35 is thus turned to the position shown by phantom lines in H6. 1 from the one shown by the dotted lines. The end of lever 35 acts to push down the third arm 30d Consequently, local time corrector finger 33 drives one tooth 21a of 24 hours indicating star wheel 21 in the clockwise direction as described above.
  • the local time digits printed on 24 hours indicating wheel 22 can be shifted independently of the localities on the locative rim.
  • clutch wheel 39 comes to the position c shown in FIG. I. In this state, the end of clutch wheel 39 is connected with minute wheel 12.

  • the world timepiece shown in FIG. 5 indicates the local time in one local time zone through an aperture 40 positioned, for example, near the crown.
  • the world timepiece shown in FIG. 6, indicates all local time digits in all local time zones printed on a wheel and rim through a colorless and transparent dial.
  • the expected local time in the local time zone is shown by arrow 41 printed on the dial.
  • the local time in 24 world-famous cities can now be read. Moreover, since the 24 hours indicating wheel is turned once each hour, the change of local time in said world-famous cities can be read.
  • the alignment and operation of the timepiece are easier than that of the usual world timepieces which must be set afier determining the difference in time.
  • the local time setting the first position of the hour hand indicating home-base time, need not be disturbed. Moreover, once the local time is set, a change in the local time can be read thereafter.
  • the local standard times in 24 world-famous cities are indicated, and furthermore the changes of the local times can be read without any questions. Even if the wearer moves into a new time zone, there is no need of some operations, therefore the timepiece is very convenient in practical use.
