added function that prevents it from being rotated in the counterclockwise

direction to make it much safer. A register ring that can not be turned in the

counterclockwise direction.

2. The screwlock type crown with double O-ring.

The crown is a screwlock type which uses a double O-ring type with 3 water

resistant packings to improve airtightness and water resistance.

3. The “No decompression limits table” imprinted on the wrist band (There are

some models without this table) to enable divers to dive safely.

The “No decompression limits table” is indicated on the wrist band to enable

divers to dive safely.

normal conditions to prevent free rotation, and can not be turned in the

reverse direction for safety reasons.

certain required time, and the remaining time can be read with the ring scale.

E. NO DECOMPRESSION LIMITS TABLE

The range of time when it is unnecessary 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.
