A black-dial diver on a steel bracelet is the most versatile watch you can own, and the Tissot Seastar 1000 40mm delivers that formula with Swiss build quality and a slim, comfortable case. It is the sort of watch that looks right with a suit on Monday and a swimsuit on Saturday.

Tissot kept the profile to just under 10mm, which is notably slim for a 300-meter diver. The rotating bezel with mineral ring tracks elapsed time, the screw-down crown and caseback seal out water, and the black dial with index markers and luminous hands keeps everything crisp and easy to read. A sapphire crystal with anti-reflective treatment on both sides finishes the package.

Swiss quartz means grab-and-go convenience with no winding or setting, and the quick-release bracelet lets you change its character in seconds with any compatible Tissot strap.
