no. 1 Embodiment

[0035] Such as image 3 and Figure 4 As shown, the world watch 1 is composed of a dial 3, an hour hand 5, a minute hand 7, a second hand 9, a driving device (not shown), a watch case 11, a surface cover 13, a handle 15, a rotating ring 17, a watch ring 19, and a concave-convex part 21 and display unit 23.

[0036] The dial 3 is disc-shaped, and is arranged equiangularly on the same circumference to represent 12 large marks from 1 o'clock to 12 o'clock and the time display part 29 representing 60 small marks from 1 minute to 60 minutes. The large mark and the small mark form approximately a triangle and a circle, respectively. On the other hand, the small marks are arranged outside the large marks. The hour hand 5 has a base that is fixed at the center O of the dial 3 and can rotate freely, and makes one revolution every 12 hours. The minute hand 7 has a freely rotatable base fixed at the center O of the dial 3 and makes one revolution every 60 minutes. The center O of th...

no. 2 Embodiment

[0068] Such as Figure 8 to Figure 1 As shown in 0C, the World Watch 51 is different from the World Watch 1 in the arrangement of the bezel and the display portion. On the other hand, in the world watch 51 , the same reference numerals are assigned to the same components as those of the world watch 1 .

[0069] Such as Figure 8 And shown in Fig. 9, world table 51 is made up of dial plate 3, hour hand 5, minute hand 7, second hand 9, drive unit (illustration is omitted), watch case 11 ', surface cover 13 ', crown 15, display portion 23, table The ring 53 and the operation part 57 are composed.

[0070] The dial 3, the hour hand 5, the minute hand 7, the second hand 9, the driving device, the display part 23 and the bezel 53 are accommodated inside the watch case 11'. The watch case 11' is composed of a first case main body 31, a fixing ring 33', a second case main body 35, a bottom cover 37, a first gasket 39, and a second gasket 41'. The first case main body 31 constitute...

no. 3 Embodiment

[0078] Such as Figure 11 and Figure 12 As shown, the shape of the display portion of the world watch 71 is different from that of the world watch 1 . On the other hand, in the world watch 71 , the same reference numerals are assigned to the same components as those of the world watch 1 .

[0079] Such as Figure 12 As shown, the display portion 73 is a belt-shaped member wound helically about four times on the surface of the case ring 19 and rotates integrally with the case ring 19 . The distance between the both ends of the display part 73 becomes narrower as it approaches the front-end|tip 75a, 75b. The front end 75a is shifted clockwise by 90° from the front end 75b. The first imaginary line 77a connects the front end 75a and the axis O of the bezel 19 . The second imaginary line 77b connects the front end 75b and the axis O of the case ring 19 . The third imaginary line 77c is shifted clockwise by 30° from the first imaginary line 77a. The fourth imaginary line 77...

Abstract

The invention relates to a world clock, especially world clock for reading the time of the main city or the main country. The world clock is composed of watch case, revolving ring, watch ring and showing part. The watch has an hour hand and a minute hand and a dial plate in a case. Outside the dial plate, the case has a revolving ring rotatable freely regardless of the rotation of the hour hand and the minute hand. The watch ring is at the inner circle of the revolving ring and rotates together with the revolving ring. On the surface of this watch ring, there is a showing part of spiral design. In the center part of the spiral design , marks representing universal time are provided, and the longitude is assigned in the area between the center part and the ends and marks representing the city name (or country name) corresponding with the longitude are in the area.

Description

[0001] technology area [0002] The present invention relates to a world watch, and more specifically, relates to a world watch capable of reading the time of major cities or countries in the world. Background technique [0003] A world watch capable of reading the time in major cities of the world is under development. There are two types of world watches: 24-hour and 12-hour. [0004] The 24-hour world watch has a 24-hour hand that rotates in 24 hours, and a ring that records the names of major cities in the world. From the multiple city names recorded on the ring, the user adjusts the ring so that the city name where he is located coincides with the 24 hour hand, so that the user can know the local time of each city. However, in a 24-hour world watch, because the angle at which the 24-hour hand indicates the time is not the same as the angle at which the hands of a normal watch indicate the time, it is difficult for the user to grasp the correct time. [0005] The 12-hou...
