The Tissot Seastar 2000 Professional Powermatic 80 [T120.907.37.041.00] is Tissot's most aggressive and technically capable diving watch, combining professional underwater performance with a bold stealth-inspired aesthetic.

Built to meet the demands of serious diving environments, the Seastar 2000 Professional delivers exceptional durability, extreme water resistance, and advanced Swiss mechanical engineering within a purpose-built professional dive watch platform.

The watch features a striking blue gradient dial with embossed wave pattern, creating depth and visual texture inspired by the ocean itself. Large luminous hands and indexes ensure exceptional legibility in low-light conditions and underwater environments.

What distinguishes this reference from other Seastar models is its black PVD-coated stainless steel case, giving the watch a more tactical and contemporary appearance while emphasizing its professional tool-watch character.

Surrounding the dial is a highly durable black ceramic unidirectional rotating dive bezel engineered to withstand years of use while maintaining its appearance and scratch resistance.

Designed for extreme underwater environments, the Seastar 2000 Professional offers an extraordinary 600 metres (2,000 feet) of water resistance, supported by a screw-down crown, screw-down caseback, and automatic helium escape valve. These features allow the watch to meet the demands associated with professional diving applications. 

At its heart beats the proven Powermatic 80 automatic movement, providing up to 80 hours of power reserve. The inclusion of a Nivachron™ balance spring enhances resistance to magnetic fields, shocks, and temperature variations encountered during everyday wear.
