The register-ing can be used for various other activities
besides diving, for example parking, walking, and
keeping track of the remaining time before departing
or before meeting a friend, or however you like.
E. NO DECOMPRESSION LIMITS TABLE
The range time when it is necessary to stop to
decompress while surfacing from a dive is
determined by the depth and time of the dive.
These values are referred to as “No Decompression
Limits”. Use these as estimates when diving.
No Decompression Limits, based on the American
Navy Diving Manual (1983), are printed on the band
of this watch. (Some models may not have this chart).

Caution: The no decompression limit is different
depending on body condition, or personal differences.
Please use the no decompression limits on this
watch as a guideline.
When a dive requires no decompression limits make
sure you follow a specialized diver’s manual.
Example: If the diver is at 21 metres for 50 minutes
or less, then it is OK to surface without stopping to
decompress.
F. CARE OF YOUR WATCH
1. Water resistant... Confirm the degree of water
resistance of your watch by the case back and dial
and refer to the following table for the use of your
watch. The crown must be pushed in at all times.
Also on screwlock-type crowns, screw should be
tightened completely.
