Crown Operations
The crown of this watch is a screw in lock crown. Before using
the crown, you must fi rst rotate it towards you to loosen it.
Important!
• To maintain water resistance and avoid impact damage
to the crown, be sure to screw it back in when you are not
using it.
• When pulling out the crown, avoid using undue force,
which creates the risk of personal injury to your fi ngers and
fi ngernails, and of watch malfunction.
