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.

If your watch has a rotary bezel...

You can rotate the bezel to align its ▼ mark with the
minute hand. Then you will be able to tell how much
time has elapsed since aligning the ▼ mark.
