Product Overview
The Tissot Men’s Seastar 1000 Powermatic 80 is a Swiss-made automatic watch built for those who demand reliability and precision in challenging aquatic environments. Designed with serious water sports enthusiasts in mind, it combines professional-grade dive functionality with everyday wearability. At its core is the robust 316L stainless steel case, engineered to resist corrosion from saltwater and withstand the physical demands of underwater activity. The unidirectional ceramic bezel allows for accurate tracking of dive times, rotating only counterclockwise to prevent accidental miscalculations that could compromise safety. With a water resistance rating of 30 bar—equivalent to 300 meters or 1000 feet—this watch is suitable for recreational scuba diving, snorkeling, and extended surface water exposure. Critical components like the screw-down crown and caseback are designed to maintain a watertight seal, protecting the internal mechanics even under pressure. Powered by the Swiss Powermatic 80 automatic movement, it offers self-winding operation and an extended 80-hour power reserve, ensuring consistent performance whether worn daily or kept in reserve for weekend adventures.
Key Features
- Swiss Automatic Movement (Powermatic 80): This in-house developed movement provides reliable, maintenance-free timekeeping without the need for batteries. Its 80-hour power reserve means the watch remains operational for over three days without being worn, ideal for those who alternate between multiple timepieces or travel frequently.
- 300-Meter Water Resistance: Rated for depths up to 30 bar, this watch meets the standards for recreational diving and prolonged underwater use. It’s built to perform in real-world aquatic conditions, from pool training to open-water exploration.
- Unidirectional Ceramic Bezel: Crafted from scratch- and fade-resistant ceramic, the bezel features clear, high-contrast markings for easy reading at a glance. Its one-way rotation prevents accidental advancement, a critical safety feature for tracking elapsed dive time.
- 316L Stainless Steel Case and Bracelet: Known for its excellent resistance to rust and pitting, 316L stainless steel is the industry standard for marine-grade applications. The case and matching bracelet feature a combination of polished and brushed finishes, offering a balanced aesthetic that transitions seamlessly from sport to casual wear.
- Screw-Down Crown and Caseback: These sealed components ensure that water cannot penetrate the watch during submersion. The screw-down mechanism requires deliberate action to open, adding a layer of protection against accidental exposure.
- Grey Dial with Luminous Markers: The dark grey dial enhances contrast, making it easier to read in bright or low-light conditions. The hands and hour markers are treated with luminescent material, providing visibility in murky waters or nighttime environments.

Important Notes
To maintain optimal performance, it is recommended to rinse the watch with fresh water after exposure to saltwater, chlorine, or other corrosive elements. This simple step helps preserve the finish and functionality of the case, bracelet, and seals. The crown should not be operated while submerged unless the watch is specifically being used for diving. For long-term reliability, periodic servicing by an authorized Tissot technician is advised. The manufacturer’s warranty is available upon request through customer service.
