Crown Operations

Loosen
Some water-resistant models (100meters, 200meters)
have a screw-in crown. When you need to perform a crown
operation, rotate it towards you to unscrew it. Then pull the
crown out. Avoid applying undue force when pulling. The watch
loses its water resistance while the crown is unscrewed. After
performing a crown operation, fully screw the crown back in.

You can rotate the bezel to align its

To adjust the time setting
When the second hand is at 12o’clock, pull
out the
Crown to stop it.
Push the Crown back in on a time signal to
