When setting the clock
1. Make sure that your watch is perfectly dry.
2. Gently pull the crown to make the necessary changes.
3. Avoid changing the date between 20:00 and 4:00
4. Once you are done setting the time, press the crown back and (depending on model) January curl to the hull, so keep the water resistance of your timepiece.
