Using your Tissot Seastar 1000 watch is easy. Simply adjust the time according to your needs. For underwater activities, use the uni - directional rotating bezel to time your dives. Just turn it clockwise to set the start time. When it comes to maintenance, keep your watch clean by wiping it with a soft cloth regularly.

Also, have your watch serviced by a professional every few years to ensure it keeps running smoothly.
