Diver's Watch with 300M Water Resistance

The Tissot Seastar 1000 is a professional diver's watch built for serious underwater use. Its stainless steel construction and screw-down crown create a reliable seal at depth. A unidirectional rotating bezel allows accurate elapsed-time tracking during dives. The green dial with index and dotted markers ensures clear legibility in low-light conditions.

Suited for Daily Wear and Recreational Diving

This model fits buyers who want a single watch for both office and ocean. The integrated stainless steel bracelet with deployment clasp offers secure, adjustable comfort. Quartz movement removes the need for daily winding or regular time-setting. Buyers who prefer mechanical movements or a lighter titanium case should look at something else.

300M Water Resistance Defines the Use Case

The 300 metre rating certifies this watch for scuba diving, not only swimming or snorkelling. A screwed case back and sapphire crystal complete the pressure-resistant assembly. If your activities stay at surface level, a lower-rated watch will also perform well.

Questions about this item

What case diameter and thickness must my wrist accommodate for the 40.00 mm stainless steel case?

The case measures 40.00 mm in diameter and 9.97 mm thick, so a strap or bracelet must clear those dimensions for a comfortable fit.

How is the screw-down crown operated before setting the time or date, and what step is often missed?

Unscrew the crown counter-clockwise until it pops free, pull to the desired position, then after setting push it back in and screw clockwise until snug to restore 300 m water resistance.

When will the quartz movement need a battery change and what must be done at that service?

Expect a battery swap every two to three years; the case back must be unscrewed, the gasket inspected or replaced, and water resistance re-tested to maintain the 300 m rating.
