Seastar 1000 Powermatic 80 Diver

The Tissot Seastar 1000 Powermatic 80 is a 300m water-resistant automatic diver's watch built for men who need a reliable tool watch. Its 316L stainless steel case measures 40.00mm thick and features a unidirectional rotating bezel, screw-down crown, and scratch-resistant sapphire crystal with antireflective coating. The grey dial carries dotted markers and a date window, driven by the Powermatic 80 calibre 11 1/2''' automatic movement. A matching stainless steel bracelet with deployment clasp completes the professional specification.

Suits serious divers and daily wearers

This watch fits buyers who want ISO-compliant dive performance, an 80-hour power reserve, and a robust steel bracelet in a single package. It is not for shoppers who need a lighter titanium case, a rubber strap option in the box, a chronograph function, or a higher beat rate movement for smoother seconds-hand sweep.

80-hour power reserve decides

The Powermatic 80 calibre delivers an 80-hour power reserve, letting the watch run through a full weekend off the wrist without reset. If your routine demands a longer reserve or a high-beat movement, this calibre will not meet that requirement.

Questions about this item

What does the 300m water-resistance rating mean for actual diving use?

The 300m rating indicates the case and crown system are tested to withstand pressures equivalent to that depth, making it suitable for serious recreational diving and prolonged water exposure.

How does the Powermatic 80 movement's 80-hour reserve change daily wear?

The automatic calibre stores up to 80 hours of energy, so the watch keeps running through a full weekend off the wrist without needing a reset on Monday.

Will the 40.00mm case thickness and 316L stainless steel bracelet fit a typical wrist?

At 40.00mm thick the case sits low under a cuff, and the solid 316L bracelet with deployment clasp adjusts to most wrist sizes without tools.
