Crown Operations
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.
