Page 14: Care And Handling During Charging
Care and handling during charging ■ Notes on use Take care to charge your watch during use. Please note that if you wear long sleeves, the watch can easily become insufficiently charged because it is hidden and not exposed to light. • W hen you take the watch off, place it in as bright a place as possible, and it will always continue to run properly. -
Page 15: Replacing The Rechargeable Cell
Replacing the rechargeable cell Unlike ordinary batteries, the rechargeable cell used in this watch does not have to be periodically replaced due to repeated charging and discharging. CAUTION Never use another battery different from the rechargeable cell used in this watch. The watch structure is designed so that a different kind of battery other than that specified cannot be used to operate it. In case a different kind of battery such as a silver battery is used, there is the risk of it becoming overcharged and bursting, causing damage to the watch and even to the wearer. -

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.
- Page 22 If your watch is a diver's watch [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. The ranges are called "No Decompression Limits". A table of "No Decompression Limits"...
- Page 23 If your watch is a diver's watch Example: Read the table as follows. 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. CAUTION • The table of no decompression limits is provided for one-time diving.
- Page 24 If your watch is a diver's watch [4] When Luminous Paint is used for your watch The paint on the dial and hands helps you with reading the time in a dark place. The luminous paint stores light (daylight or artificial light) and glows in a dark place. It is free from any radioactive substance or any other material harmful to a human body or environment.
