Comments about the data

watch and alarm driven by a single barrel

401: without date
402: with date

Operating Instruction
Wind watch and alarm: with crown at 2:30h automatically first the watch and then the alarm is wound. If a resistance appears when turning the crown towards 12h, both are completely wound up.
Set time: if the pusher at 3:30h is in down position, turn the crown a bit towards 12h (like winding); the pusher is released. Now pull the crown and set the time. If you set the time reverse and pass the alarm time, this will be set reverse simultaneously.
Set alarm: press down the pusher, pull the crown, and set the alarm time. The alarm time can only be set reverse, setting forward is inhibited by a freewheel.
Enable alarm: turn the crown a bit towards 12h (or wind it); the pusher is released.
Disable alarm: press down the pusher.
Attention: never pull the pusher!
