Abstract
1420534 Watches ZENITH TIME SA 17 Jan 1974 [6 March 1973] 02237/74 Heading G3T An hour ring 1 and an hour wheel 2 are held in one of several discrete relative orientations by means of a spring 6 fixed to the wheel 2 and having at least one arm 6a which co-operates axially with complementary means on the ring 1. The ring 1 is freely mounted on a shoulder 5 of the wheel 2 and retained by the spring and a ring 7 tightly fitted on the wheel. As shown the spring has four arms 6a with bosses 6b to engage apertures 10 in the ring 1, though a number of alternative coupling forms are envisaged. The ring 1 is driven by a pinion 11 of the motion work and the wheel 2 with its hour hand 3 may be adjusted manually relatively to the ring 1 by a wheel 12. The wheel 2 drives a calendar via a wheel 13 revolving once in twenty four hours. In an alternative embodiment, the ring 1 is fixed on a wheel (1c), Fig. 3 (not shown), carrying a second hour hand (1b).
