Seastar 1000 Diver for Daily Wear

The Tissot Seastar 1000 is a 40.00 mm stainless-steel watch built for 300 m water resistance. A Swiss quartz calibre 11 1/2''' drives the analog display with a date window. The unidirectional rotating bezel and screw-down crown make it suitable for recreational diving and everyday use.

Quartz Precision Over Long Periods

The battery-powered movement delivers consistent timekeeping without the daily winding or positional variance of a mechanical movement. Accuracy remains stable across temperature shifts typical of surface and underwater environments. A single cell powers the watch for multiple years before a change is required.

316L Case and Integrated Bracelet

The 316L stainless-steel case and matching bracelet resist corrosion from salt water and sweat. A scratch-resistant sapphire crystal with double-sided anti-reflective coating preserves legibility in bright light. The deployment clasp secures the bracelet evenly and reduces wear on the links during repeated fastening.

Questions about this item

Does the Swiss quartz movement make the watch warm on the wrist after all-day wear?

The quartz caliber produces no perceptible heat during continuous wear.

What strap tools are needed to size the 316L stainless steel bracelet?

The deployment clasp features micro-adjustment holes; a spring-bar tool or pin pusher is sufficient for link removal.

Will the 40.00 mm case and 300 m water resistance feel oversized next to my vintage 11 1/2 ligne mechanical watches?

The case diameter matches the movement's 11 1/2 ligne footprint, so proportions remain consistent with traditional diver dimensions.
