Tissot Seastar 1000 Powermatic 80 40 mm – Gradient Grey-Black Dial & Stainless Steel Bracelet (T120.807.11.051.00)

The Tissot Seastar 1000 Powermatic 80 40 mm (T120.807.11.051.00) delivers marine-inspired precision in an elegant everyday design. The graded grey-black sunburst dial provides depth and texture, paired with bold luminous markers for outstanding legibility in low-light or aquatic conditions. The 316L stainless-steel case is robust yet refined, framed by a unidirectional rotating bezel and a screw-down crown and caseback for secure protection.

Under the dial lies the Powermatic 80 automatic movement, offering an impressive 80-hour power reserve and equipped with a Nivachron™ balance spring for enhanced resistance to magnetic fields. With a 40 mm diameter and thickness of approximately 12.48 mm, this model strikes the right balance between sport and sophistication. Protection is first-rate: scratch-resistant sapphire crystal with anti-reflective coating, a transparent exhibition back to view the movement, and tested water resistance to 300 m / 30 bar (1000 ft). The robust stainless-steel bracelet is engineered for active wear, secured by a folding clasp with safety lock and push-buttons.

Every aspect — from the integrated bracelet design to the luminous batons and precise movement finish — reflects Tissot’s commitment to Swiss craftsmanship with sporting capability. Suitable for both deep water and urban settings, this timepiece merges performance, style and reliability.
