Correcting the date during this time period may prevent the date from changing on the following day. Set the date and day after the hands have moved outside this time period. The date must be changed by operating the crown on the first day of the following month in those months with less than 31 days (months having 30 days and February). 5. Helium Escape Valve An helium escape valve is provided that automatically discharges helium gas that has penetrated inside the watch to prevent the watch from rupturing when ascending from deep regions to the surface during saturation diving by professional divers using helium. 12 13 6. Using the Rotating Bezel The rotating bezel can be used as a reference for elapsed time during diving or for the amount of time remaining relative to a predetermined amount of time. Determination of Remaining Time * The remaining time can be determined by aligning the M mark on the rotating bezel with the target time. [Setting the Rotating Bezel] * Only turn the rotating bezel to the left. It cannot be rotated in the opposite direction (to the right) to prevent the risk of incorrect operation. Determination of Elapsed Time Turning direction Remaining time * Align the M mark on the rotating bezel with the minute hand. After a certain amount of time has elapsed, the elapsed time can be determined from the scale on the rotating bezel. Elapsed time 14 15 7. Before Diving Always make sure to check the following items before diving. Never attempt to disassemble or assemble the rotating bezel or rotating bezel clamp while diving. Do not bump the watch against rocks or other hard objects. 16 17 9. After diving, thoroughly rinse the watch with pure water and carefully wipe off the moisture with a dry cloth. When rinsing with water, first check to make sure that the crown is securely locked. If there is any debris or fine sand around the rotating bezel, disassemble the rotating bezel and rotating bezel clamp and remove any debris and soiling. However, never attempt to loosen or remove the screws of the back cover. 10. Disassembly and Assembly of Rotating Bezel and Rotating Bezel Clamp [Exploded View of Rotating Bezel and Related Parts] Rotating bezel clamp Rotating bezel Rotating bezel clamp locking lever Rotating bezel spring * Only disassemble the rotating bezel when necessary. Be careful not to lose or deform any of the parts during disassembly. Stopper 18 19 [Disassembly Procedure] 1. Open the rotating bezel clamp lever in the direction of the arrow while simultaneously lowering the stopper. 2. Turn the rotating bezel clamp to the right and remove (this is opposite the direction of an ordinary screw). 3. Remove the rotating bezel spring. Note: Be careful when removing the rotating bezel clamp since the rotating bezel and rotating bezel spring may fall off and become lost. Note: The rotating bezel spring is installed beneath the rotating bezel. [. . . ] · Do NOT subject the watch to a strong shock such as dropping it onto a hard floor. · Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored.
