Troubleshooting
Watch has stopped running
The Tissot Seastar uses an automatic movement. If it has not been worn for over 80 hours, give the crown 20-30 clockwise turns while in the closed position to manually wind the mainspring.
Date is changing at noon instead of midnight
The watch is set 12 hours out of sync. Advance the time forward by 12 hours to correct the AM/PM alignment.
Fog inside the crystal
This indicates a potential seal failure. Stop using the watch in water immediately and take it to an authorized Tissot service center for pressure testing.

Setup, Compatibility & Care
To set the time and date, pull the crown to the second position to adjust the hour and minute hands; pull to the first position to advance the date window located at 6 o'clock. Always ensure the screw-down crown is fully pushed in and tightened before entering any body of water to maintain the 30 bar water resistance rating. To clean your watch, rinse it with fresh water after exposure to salt or chlorinated water, and use a soft, lint-free cloth to dry it. Avoid using harsh chemicals or abrasive brushes on the black PVD coating, as these may cause premature fading or scratching of the finish.
