Tissot SeaStar 1000 300M Diver
The Tissot SeaStar 1000 Chronograph is a 300 metre water-resistant diver's watch built for serious aquatic use. A 38.00 mm stainless steel case houses a quartz movement behind sapphire crystal. A unidirectional rotating bezel and screw-down crown complete the professional specification.
Suits Divers Needing ISO Depth Rating
This watch fits wrists requiring certified 300 metre water resistance and a chronograph function for timing dives. Buyers who want a mechanical movement or a metal bracelet instead of the supplied synthetic strap should look at something else.
300 Metre Water Resistance Decides Fit
The single specification that decides suitability is the 300 metre water resistance rating. If your activity demands this depth capability the SeaStar 1000 qualifies; if you need less or more, the rating is the deciding factor.

Questions about this item
What does the 300m water-resistance rating mean for actual diving use?
The 300m rating indicates the watch is suitable for professional diving and high-pressure water sports, with a screw-down crown and unidirectional rotating bezel for elapsed-time tracking underwater.
Will the 38.00 mm case and 12.95 mm thickness fit under a standard shirt cuff?
At 38.00 mm wide and 12.95 mm thick, the stainless steel case sits relatively low on the wrist; the synthetic strap adds minimal bulk, so it slides under most cuffs without catching.
How is the synthetic strap attached, and what is the common mistake when changing it?
The strap uses standard spring bars fitted to the lugs; the frequent error is not fully compressing the bar before pulling, which can scratch the lug ends or bend the spring bar.
