Seastar 2000 Professional Diver's Watch

The Tissot Seastar 2000 Professional is a purpose-built diver's watch rated for 600M water resistance. It features a 316L stainless steel case measuring 46.00 mm thick with a domed sapphire crystal that includes antireflective coating. The blue dial uses index and dotted markers for clear legibility. This automatic timepiece suits professionals and serious enthusiasts who require certified deep-water performance.

Thermals Noise and Power Draw

As a mechanical watch powered by the Powermatic 80.111 caliber with 23 jewels, it generates no heat and produces no audible noise during operation. The automatic movement harvests kinetic energy from wrist motion, eliminating the need for battery changes or external charging. A screw-down crown maintains the 600M seal while protecting the movement from pressure and moisture ingress at depth.

Bundled Accessories and Software

The watch comes fitted with a matching stainless steel bracelet secured by a deployment clasp for quick, secure fastening. No additional straps, tools or digital software are included in the standard package. The unidirectional rotating bezel and date display are integrated functions rather than separate accessories, requiring no setup beyond standard crown operation.

Questions about this item

How is the screw-down crown operated before diving, and what step is often missed?

Unscrew the crown counter-clockwise until it releases, set the time or date, then push and screw it back clockwise until fully seated; the missed step is confirming the crown is completely tightened before water exposure.

What maintenance will the Powermatic 80.111 movement and 600 m seals require over time?

The automatic movement with 23 jewels should be serviced every three to five years, including lubrication and timing checks, while the screw-down crown and case-back gaskets must be pressure-tested and replaced during each service to maintain 600 m water resistance.

Which limit appears first during continuous wear — power reserve or thermal comfort from the 46.00 mm case?

The 80-hour power reserve typically lasts through a weekend off the wrist, whereas the 46.00 mm stainless steel case can feel warm and heavy after several hours, so thermal comfort usually becomes noticeable before the movement stops.
