Abstract

1304608 Date indicating SUWA SEIKOSHA KK 20 May 1970 [21 May 1969] 24440/70 Heading G3T Axial movement of a winding stem 12 of a calendar time-piece 10 causes an angular displacement of a setting lever 15 through a pin 14 engaging a groove 13. When the stem has been depressed by a short distance a nose portion 17 depresses a pin 20 of a correcting member 21 which, through a projection 41, moves a tooth 42 of a day star wheel 31 to advance the day indication by one day. When the stem is depressed further, a stepped portion 43 of the correcting member engages a tooth 35 of a date wheel 34 so as to additionally advance the date indication.
