Tissot Seastar 1000 Chronograph 120.217.11.061.00 300M Watch

300 m diver chronograph

The Tissot Seastar 1000 Chronograph is a stainless-steel dive watch rated to 300 m water resistance. It carries a quartz movement and a unidirectional rotating bezel for elapsed-time tracking. The 38.00 mm case fits wrists that prefer a traditional diver profile. It is aimed at buyers who want a capable tool watch with a black dial and dotted markers.

Quartz timing limits

Quartz regulation keeps daily rate variation to a few seconds per month without winding. The chronograph function measures short intervals but does not replace a dedicated stopwatch for laboratory precision. Battery changes are required every few years, so the case back must be resealed to maintain the 300 m rating. Buyers who want a mechanical movement or a perpetual calendar will need a different watch.

300 m water resistance

The single specification that decides suitability is the 300 m water-resistance rating combined with the screw-down crown and sapphire crystal. This depth rating supports serious recreational diving and high-impact water sports. If the intended use stays at surface level only, a lower-rated model would suffice.
