<p>PCT No. PCT/CH79/00073 Sec. 371 Date Jan. 23, 1980 Sec. 102(e) Date Jan. 7, 1980 PCT Filed May 22, 1979 PCT Pub. No. WO79/01104 PCT Pub. Date Dec. 13, 1979.World watch with a single hand (9) comprising a watch mechanism in a case, a bezel (2) above the case, a face (3) and a hand (9), together with a back, said assembly forming an internal body which is mounted in a relatively easy manner within an external locking ring (6). The said ring is located in a peripheral groove (12) formed by the bezel (2) and the back. The body can be rotated in a stepwise manner, as it is locked in each position by means of a locking device comprising two bosses (13) on the locking ring (6) and slots (14) on the bezel (2). One of the attachments (7) carries a numeral (16) and the bezel (2) is provided with a mark (17). By rotating the body, the mark moves away from the stationary numeral. The difference, determined in hours on face (3) which carries no numbers, gives the time variation between different time zones throughout the world.</p> |
