SET IT AND FORGET IT. The 420 SS is a High Quality Quartz Japanese Miyota Movement. Battery Operation. 

The Island Time 420 SS is rated for general water use such as Swimming / Free Diving / Snorkeling etc. (It is NOT rated for extreme water sports or deeper than 100ft scuba diving which can introduce higher than 10ATM dynamic pressures; internal leakage could occur.)

After contact with salt water we recommend you rinse your island time 420 SS in fresh water. 


NEVER open the crown to set the date or time while in water or even after exposure to water or moisture.

After exposure to water or moisture Always wait at least 4 hours or to make sure your watch is completely dry before opening the crown. Opening the crown while your watch is wet or has moisture on it can cause water intrusion / fogging or damage to the internals.
