IF YOUR WATCH IS A DIVER'S WATCH [1] Precautions when Using during Diving: * When using a diver's watch, please make sure that you have received the proper education and training for various types of diving, and observe all rules. * Please make sure to use the watch properly based on a thorough understanding of watch handling and precautions. Please note that failure to operate the watch in a manner not described in the user's manual may prevent the watch from functioning properly. <Before Diving> * Please make sure that the crown is pushed in firmly and the screw is securely tightened. * Please confirm that there are no cracks, scratches, chips or other abnormalities in the band and glass. * Please check that the time and date are set correctly. * Please check that the second hand is moving properly. If the second hand is moving at two-second intervals, this means that the watch is not sufficiently charged. <During Diving> * Never attempt to turn or pull out the crown underwater. * Be careful to avoid bumping your watch on hard objects such as diving equipment or rocks. <After Diving> * Completely wash off any sea water, mud or sand adhered to the watch with pure water after checking that the crown and screw are tightened. Wipe off any excess moisture with a dry cloth. 14 15 Elapsed time: shows that 10 minutes have passed since 9:10. Remaining time: shows that 20 minutes remain until 9:25. The rotating bezel can be used for various other activities besides diving, for example parking, walking, and keeping track of the remaining time before an important appointment. 16 10 20 [2] How to use Rotating bezel The rotating bezel is a convenient way to keep track of diving time, permitting the indication of the elapsed and remaining times. It is locked under normal conditions to prevent free rotation, and cannot be turned in the reverse direction for safety reasons. * Determination of elapsed time: Align the Z mark on the rotating bezel with the minute hand. * Determination of remaining time: Align the Z mark on the rotating bezel to a certain required time. The remaining time is read with the ring scale. 50 30 40 40 20 50 Elapsed time Remaining time 30 10 17 [3] No decompression limits The range within which the diver can rise to the surface without rest for decompression is determined by the depth and elapsed time of the dive. A table of "No Decompression Limits" compiled according to the U. S. Navy Diving Manual (1993 edition) is printed on the watchband of this watch (there are some models that do not have this table on the watchband). No Decompression Limits N. D. LIMITS CAUTION · The table of no decompression limits is provided for one-time diving. · Since the no decompression limits differ depending on the diver's physical condition and varies among individuals, use this table as a guideline only. · In case of diving that requires the diver to take a rest for decompression before rising to the surface, perform diving following a manual exclusively compiled for diving. -How to read no decompression limitsDEPTH. m N.

In case the maximum diving depth is 21m(70ft) and the elapsed time is 50 minutes or shorter, the diver is not required to take a rest for decompression while rising to the surface. 18 19 [4] Note on the luminous dial · The luminous paint used for the dial of this watch is mainly made from a luminescent material, which is harmless to the human body and the environment since it contains no toxic substances such as radioactive materials. This luminous paint stores light of the sun and indoor lighting and emits light in a dark place. [. . . ] · 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. 26 27 l.
