TISSOT Seastar 2000 Professional T120607A (T120.607.17.441.00) Automatic Movement Overhauled, with Original Bracelet & Rubber Strap, Used

The TISSOT Seastar 2000 Professional (T120607A / T120.607.17.441.00) is Tissot's flagship diver's model, equipped with practical specifications to meet the demands of professional divers.
This model features a striking black dial. While it typically comes standard with a rubber strap, this unit will be sold with a genuine metal bracelet attached. The set also includes the original rubber strap, allowing you to enjoy it as a rubber-strapped model as well.

Professional Design

The thick case, equipped with a ceramic unidirectional rotating bezel and a helium escape valve, gives it the rugged elegance characteristic of a diver's watch.
The dial features an engraving reminiscent of waves, ensuring high legibility through the anti-reflective sapphire crystal.
At its heart is the automatic movement "Powermatic 80," boasting a long power reserve of up to 80 hours. Furthermore, by adopting a highly magnetic-resistant Nivachron hairspring, it maintains stable accuracy even in today's magnetic environments.

Includes Genuine Bracelet & Rubber Strap

The substantial 46mm diameter and 16.3mm thick case provide a noticeable weight on the wrist.
In addition to the already-attached TISSOT genuine stainless steel bracelet, a spare genuine rubber strap is also included. The robust bracelet, supporting a heavy-duty, professional-spec diver's watch, offers a profound sense of quality.
*The strap replacement on this model uses standard spring bars. Please use appropriate tools (spring bar remover) when replacing.

This set, featuring a simple black dial not found in the current lineup and including the genuine bracelet sold separately, is a must-have for its combination of practicality and rarity.

Reference Retail Price: 163,900 yen (as of 2025) + genuine bracelet sold separately

Condition

This watch has been overhauled.

While there are scuffs and dents from practical use on the edges of the bezel, case edges, and bracelet, there is no fatal damage, and it poses no practical problems.
There are minor scratches on the glass surface, visible in the images, but the legibility of the dial and hands is good.

The genuine bracelet and genuine rubber strap are included. The bracelet is of sufficient length and can accommodate a wrist circumference of up to 198mm.

The screw-down crown's screwing action is also good.
Please handle it carefully to avoid stripping the threads.
If the crown threads are damaged, please consult the manufacturer for repair.

As this is a USED item, there is no waterproof guarantee.
