Inventory #619
Sale Price: $4,350 OBO

A distinctive, discontinued-generation Tissot Seastar 1000 Automatic Chronograph created for enthusiasts who appreciate substantial Swiss mechanical sports watches.

This blue Seastar combines a commanding 48mm stainless-steel case, automatic mechanical chronograph movement, sapphire crystal, 300-meter / 1,000-foot water resistance, and a factory transparent exhibition caseback that allows the mechanical movement to be viewed.

The blue dial, matching blue bezel and blue rubber strap create one of the most striking configurations from this generation of the Seastar family.

Collector History & Production Era

This Tissot Seastar 1000 Automatic Chronograph, Ref. T066.427.17.047.00 / case reference T066427A, belongs to the circa 2010–2014 generation of the Seastar 1000 Automatic Chronograph.

For collectors, an important distinction is that circa 2010–2014 describes the production era associated with this reference/model generation. It does not establish the exact manufacturing year of this individual Inventory #619 watch. The individual production year has not been independently verified and should only be represented as exact if confirmed through original documentation, serial information or authoritative Tissot records.

This generation is notable for combining substantial dive-watch specifications with an automatic mechanical chronograph and factory exhibition caseback.

Swiss Automatic Chronograph

At the heart of this Seastar is the ETA C01.211 automatic mechanical chronograph movement, associated with an interesting generation of Tissot mechanical chronographs.

Rather than relying on a battery-powered quartz mechanism, the watch is mechanically powered through its automatic winding system.

The transparent caseback provides a view into the mechanical movement—an especially appealing feature for enthusiasts who enjoy seeing the engineering behind their watches.

Approximate power reserve: 45–46 hours.

48mm Statement Case

At approximately 48mm, this is an unapologetically substantial sports watch.

Its stainless-steel construction, prominent chronograph pushers, large crown, blue bezel and highly legible dial give the watch the bold character associated with this generation of Seastar.

The blue rubber strap complements its professional aquatic styling while maintaining a sporty appearance.

300M Seastar Capability

The Seastar name has long represented Tissot’s sports and aquatic-watch heritage.

This model was specified with:

300 meters / 1,000 feet water resistance
Sapphire crystal
Rotating diver-style bezel
Stainless-steel case
Rubber strap

Because this is a previously owned/discontinued mechanical watch, water resistance should be pressure-tested by a qualified watchmaker before swimming or diving, regardless of the watch’s original factory rating.

Why Collectors May Appreciate This Seastar

Its design is also distinctly different from later generations of the Seastar, giving it an identity of its own within Tissot’s modern sports-watch history.
