Swiss Automatic Dive Watch with Bold Two-Tone Styling

The Tissot Seastar 1000 Powermatic 80 40mm Black Two-Tone Watch blends professional dive-watch capability with a more refined and elevated everyday look. Built from 316L stainless steel with yellow gold PVD accents, this model combines sporty performance with standout wrist presence, making it ideal for both active lifestyles and daily wear. The 40mm case size delivers balanced proportions on the wrist while maintaining the robust feel expected from the Seastar collection.

Powered by the Swiss Powermatic 80 automatic movement, the watch delivers an impressive up to 80 hours of power reserve, allowing it to continue running for days off the wrist. Designed for modern daily wear, the movement also benefits from a Nivachron™ balance spring, helping improve resistance to magnetic fields and enhancing long-term reliability. A see-through exhibition caseback reveals the movement in motion, adding extra appeal for enthusiasts who appreciate mechanical watchmaking.

The bold black dial creates strong contrast against the luminous gold-tone hands and indexes, ensuring excellent readability in darker conditions and underwater environments. A practical date display at 6 o’clock keeps the layout clean and balanced, while the black unidirectional bezel reinforces the watch’s sporty dive-watch character.

Built for demanding conditions, the Seastar features a screw-down crown, unidirectional rotating bezel, and impressive 300m water resistance, making it a true dive-ready Swiss sports watch. A scratch-resistant sapphire crystal helps maintain long-lasting clarity and durability through daily wear, travel, and more active use.

The integrated two-tone bracelet combines brushed and polished finishes for a more premium appearance while remaining comfortable enough for all-day wear. Its folding clasp with diver extension adds extra practicality for active lifestyles and watersports.
