English SCREW DOWN CROWN • Your watch has a screw down crown to prevent accidental operation and help maintain water-resistant quality. • To use the crown, it is necessary to unlock the crown first before pulling it out, and it is important to securely screw the crown in after each use. HOW TO OPERATE THE SCREW DOWN CROWN The crown must be securely locked in the case except when you use it to set the watch. Turn the crown counterclockwise to unscrew it. The crown is released and projected outward from its original position. The crown is unlocked and can be pulled out. Turn the crown clockwise while pressing it to the case until it is screwed all the way in and locked. The crown is locked. 1. Before diving, make sure that the crown is locked tightly in place. 2. Do not operate the crown when the watch is wet or in water. 3. When screwing the crown in, ensure that the crown is correctly aligned and turn it gently. If it is hard to turn, unscrew it first, and then rewind it. Do not screw it in by force as it may damage the thread of the screw or the case. 18 English SECURITY LOCK BUTTON OPERATION SECURITY LOCK OF PUSH-BUTTONS A & B A Locking Unlocking Locking B Unlocking Unlocking the push-buttons - Turn Security Lock Buttons counterclockwise until you no longer feel the threads turning. - The buttons can be pushed in.
