Tissot Seastar Chronograph Watch - Tissot Seastar 1000

Yes, with an impressive water resistance of 30 bar (300 meters), a unidirectional rotating bezel, and a screw-down crown, this watch is designed to meet the demands of professional diving.

Always ensure the crown is fully screwed down before exposing the watch to water. After use in saltwater, rinse the watch thoroughly with fresh water. Have the watch serviced every 3-5 years by an authorized Tissot service center to check and replace seals.

The unidirectional bezel is a critical safety feature for divers. It allows you to mark a specific point in time (e.g., start of a dive) and only rotates counter-clockwise. This prevents accidental bumping from falsely indicating less elapsed time, which could lead to dangerous overestimation of remaining air or decompression limits.

Yes, as it features a Swiss quartz movement, it operates on a standard watch battery. The battery typically lasts several years, and it should be replaced by an authorized service center when needed to maintain water resistance.

While highly water resistant, rapid and extreme temperature changes, such as those found in hot tubs or saunas, can put stress on the watch's gaskets and compromise its water resistance over time. It is generally recommended to avoid wearing diving watches in such environments.

Tissot generally recommends a full service every 3 to 5 years, especially if the watch is regularly exposed to water or harsh conditions. Regular servicing helps maintain the movement's accuracy, lubricate components, and ensure the integrity of its water-resistant seals.

The Tissot Seastar 1000 Chronograph features a scratch-resistant sapphire crystal. Sapphire is highly durable and offers excellent clarity, protecting the dial from daily wear and impacts.

For a quartz watch, this often indicates a low battery. Visit an authorized service center to have the battery replaced. Also, keep the watch away from strong magnetic fields as they can affect quartz accuracy.

After exposure to saltwater or sand, small particles can get lodged around the pushers. Rinse the watch thoroughly with fresh water while actuating the pushers gently (only when completely dry and clear of debris) to dislodge any buildup. If the issue persists, seek professional service.

Dirt, salt, or debris can accumulate under the bezel. Clean the bezel by rinsing it under warm, running fresh water, gently rotating it back and forth to help flush out any particles. A soft brush can be used carefully. If still stiff, an authorized service center can clean and lubricate it.

This is a serious sign that the watch's water resistance has been compromised. Immediately take the watch to an authorized Tissot service center. Do not attempt to dry it yourself, as moisture can quickly damage the movement.

The Super Luminova® needs to be 'charged' by exposure to light. Ensure the watch has been exposed to sufficient natural or artificial light for some time (e.g., several minutes in bright light) before expecting it to glow in the dark.
