What a inconvenient watch!
This watch will STOP!! (If a stem is not wound.)
This watch is INACCURATE!! (It have an error a few minutes in a month. It must be adjusted to the correct time on a regular basis.)
Old Watch is simple and like mechanical hand wind watch.
Using this watch is the work which requires much care. OK?
First, you swipe from right to left on the crown about 20 times, start working.
Then, swipe up on the crown, adjust the time.
Winding the stem until full, Old Watch will work about 2 days.
So, it is recommended that wind up every day.
