Do not expose your watch to water unless it is marked with WATER RESISTANT on the case back.
Always keep the crown fully pushed in, as in the outer position the watch will not run.
If your watch has a screw down crown (usually featured on professional diving models), be sure to keep it in the locked position, except when setting the time or date. Failure to do so can result in water damage to the watch movement, and the voiding of your warranty. To lock the crown, press it inward (towards case) and turn it several times in a clockwise direction, until it stops. To unlock the crown (to set date or time), simply turn several times in a counterclockwise direction.
Do not try to wind your watch manually, as it is battery operated and does not require winding.
Do not attempt to open the watch to replace the battery yourself, or for any reason, as this operation must be performed by a qualified jeweler under very controlled dust free conditions.
Always have crown, crystal, or case back replaced at once, when damaged, to prevent exposure to dust or humidity.
