Abstract

1484813 Calendar watches TIMEX CORP 17 Jan 1975 [8 April 1974] 2170/75 Heading G3T In a calendar watch 10 having a wheel 32 which is rotated once per day and carries members 42, 43 which respectively advance a date ring 18 and a day of the week dial 17, the members are in the form of tabs projecting upwardly from the wheel in planes at right angles to each other. The indicators 17, 18 are supported by a member 58 and carry day and date indicia 11, 12 visible through windows 13, 14 in a dial 16. The wheel 32 is driven continuously by toothing 31 on hours hand arbor 27. The tabs and teeth are so arranged that a date ring tooth 44 is engaged by tab 42 prior to midnight, while a day dial tooth 46 is engaged by tab 43 after midnight, to reduce the load on the watch drive. The indicators 17, 18 are held by respective jumpers (48, 52), Fig. 1 (not shown) which also complete each indicator step. If the hands are moved backward through midnight by means of a stem (21), the day dial 17 is moved in the reverse sense but the date ring 18 remains stationary since the tab 42 slips over the inclined faces of the teeth 44.
