Do not operate the crown or buttons underwater.

While diving Cation-2

Take care not to bump the watch against hard objects such as rocks.

After diving Cation-2

Rinse the watch in fresh water to wash out all seawater and wipe it thoroughly dry to prevent rust.
Avoid pouring running water onto the watch directly from a faucet. Put some water into a bowl first, and then soak the watch in the water to wash it.

CAUTION

Depending on the environment where a diver’s watch is used, its inner parts or movement as well as its case or band may be affected. We recommend that you have your watch overhauled regularly once every 2 or 3 years.

Structure of the case

In the following types of models, take care of the following issues in usage.

The bezel or protective outer case is securely fastened to the watch with setscrews.
Never loosen the setscrews.
