Purpose and Audience

The Tissot Seastar 2000 Powermatic 80 is an automatic diver watch built for men who need reliable performance at depth. Its 600 metre water resistance and unidirectional rotating bezel support professional diving requirements. The 46 mm stainless steel case and silicone strap provide durability for daily wear. Luminous hands and index markers ensure legibility in low light.

Fit and Alternatives

This watch suits buyers who want a Swiss automatic movement with an 80 hour power reserve and a screw-down crown for secure sealing. The see-through case back appeals to enthusiasts who appreciate viewing the 23 jewel movement. Buyers seeking a smaller case diameter or a lighter titanium construction should consider other models. Those requiring integrated smartwatch functions or solar charging will not find them here.

Deciding Specification

The single specification that decides suitability is the 600 metre water resistance rating. This depth rating certifies the watch for saturation diving and high-pressure underwater work. If your activities remain within recreational limits, a lower rating may suffice. If you operate at professional depths, this specification confirms the watch meets the necessary standard.

Questions about this item

Does the automatic Powermatic 80 movement generate noticeable heat or noise during all-day wear?

The mechanical movement runs silently and produces no perceptible heat on the wrist.

What strap width matches the 46 mm case lugs for a replacement band?

The case accepts standard spring bars; the included black rubber strap is fitted at the factory and can be swapped for any compatible band.

Will the 16.3 mm case thickness and 600 m water resistance still suit daily wear alongside older, slimmer watches?

The 46 mm stainless steel case sits higher on the wrist than vintage models but remains comfortable for everyday use.
