Crown Operations
Some water-resistant models (100meters, 200meters) 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.

When the battery of the 3-hand clock goes low, its second hand will start jumping at two-

of the 2-hand clock battery (Type SR516SW) is also recommended at this time.
