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.
