Abstract (en)
[origin: US2018284697A1] A wristwatch with a gear train for rotatably advancing in cyclic steps a minute-units disk, a switching device for advancing a minute-tens disk and an hour ring which is advanced during one revolution of the minute-tens disk. The movement comprises a first and a second transmission chain connected to a release mechanism; the first transmission chain controls the second such that the second transmission chain transmits every minute a rotational movement force to a minute-units wheel. The release mechanism comprises a control disk, two release levers, each having a first and a second lever arm, and a release wheel. After each minute, a first lever arm falls from the control disk edge into a recess of the control disk and a second lever arm releases the release wheel, such that the second transmission chain rotates freely, allowing the minute-units disk to rotate one digit further.
