Diver's chronograph with 30 bar water resistance
The Tissot Seastar 1000 Chronograph is a men's wristwatch built for serious watersports. Its 316L stainless steel case measures 45.5 mm across and 46.00 mm thick, topped with a sapphire crystal. A Swiss quartz movement powers the analog dial with dot markers and a date window, while a unidirectional ceramic bezel tracks elapsed time underwater.
Standalone timepiece requiring no external
The watch fastens with a stainless steel bracelet and deployment clasp, fitting directly on the wrist without tools or adapters. The screw-down crown and caseback seal the movement against water entry up to 300 m or 1000 ft. No charging, pairing or software setup is needed; the quartz calibre runs independently once the battery is installed.
Replaces basic sports watches lacking ISO-grade
Buyers moving up from fashion chronographs or entry-level dive models gain a certified 30 bar pressure rating and a screw-down crown system. The jump is worth it when regular swimming, snorkelling or recreational diving demands a case and crown proven at 300 m. It is not for buyers who need a smartwatch with notifications, GPS tracking or heart-rate monitoring.

Questions about this item
How deep can the 30 bar water resistance take the Seastar 1000 chronograph before the limit is reached?
The watch is rated to 30 bar, which equals 300 metres or 1000 feet of water resistance, so the pressure limit is reached at that depth.
Does the 316L stainless steel case and ceramic bezel stay cool and quiet during all-day wear?
A quartz movement produces no mechanical noise, and the 316L stainless steel case with ceramic bezel remains at skin temperature during continuous use.
What strap or tool is needed to fasten the 45.5 mm case on the wrist?
The integrated stainless steel bracelet with a deployment clasp is already fitted, so no extra strap or tool is required to wear it.
