The Tissot Seastar 1000 GMT is a precision dive instrument built for travellers who demand robust engineering and dual-timezone capability. Housed in a 40mm round stainless steel case, this Swiss quartz timepiece features a striking black dial offset by a bi-directional rotating bezel in black and green—a colour scheme that enhances legibility and adds distinctive character. The GMT complication allows simultaneous tracking of a second time zone, ideal for international business or leisure travel, while the date window at six o'clock ensures day-to-day practicality.
Water-resistant to 300 metres, the Seastar 1000 GMT is engineered to withstand serious aquatic environments. Its screw-down crown and caseback provide secure sealing, and the scratch-resistant sapphire crystal protects the dial from the rigours of daily wear. Luminous hour markers and hands guarantee visibility in low-light conditions, a critical feature for any serious dive watch. The integrated stainless steel bracelet delivers both comfort and durability, securing the timepiece firmly on the wrist whether you're exploring coral reefs or navigating city streets.

FAQ
Q: What is the GMT complication and how do I use it?
A: The GMT function allows you to track a second time zone simultaneously. The additional hand on the dial completes one rotation every 24 hours and corresponds to the numbered bezel, enabling you to read home time while the main hands display local time. Rotate the bezel to align with your reference timezone.
Q: Is this watch suitable for scuba diving?
A: Yes. With 300 metres of water resistance, screw-down crown and caseback, and a rotating bezel for timing, the Seastar 1000 GMT is built to ISO 6425 dive watch standards and suitable for recreational scuba diving.
Q: What type of battery does this watch use and how long does it last?
A: This Swiss quartz movement typically uses a standard watch battery with an expected lifespan of approximately two to three years, depending on use. Our service team can replace the battery and pressure-test the watch to maintain its water resistance.
Q: Can the bracelet be adjusted to fit my wrist?
A: Yes. The stainless steel bracelet can be sized by removing or adding links. Visit our boutique for complimentary professional sizing, or contact us for sizing instructions if purchased online.
Q: Does the sapphire crystal scratch easily?
A: Sapphire crystal is one of the hardest materials used in watchmaking, second only to diamond. It is highly resistant to scratches from everyday wear, though it can chip if subjected to extreme impact.
Q: Is this watch covered by an international warranty?
A: Yes. This timepiece is covered by a 2-year international Tissot warranty when purchased from an authorised retailer such as Cassims & Co. Full warranty details are provided at the time of purchase.
Q: Can I wear this watch while swimming in the ocean?
A: Absolutely. The 300-metre water resistance and screw-down crown make this watch ideal for ocean swimming, snorkelling, and diving. Rinse with fresh water after exposure to saltwater to maintain the bracelet and seals.

Care Guide
- Rinse the watch with fresh water after exposure to saltwater, chlorine, or sweat to prevent corrosion and maintain seal integrity.
- Dry the watch and bracelet thoroughly with a soft, lint-free cloth after rinsing.
- Ensure the screw-down crown is fully tightened before any water exposure to maintain water resistance.
- Avoid operating the crown or bezel while the watch is wet or submerged.
- Have the watch pressure-tested annually if used regularly for diving, and whenever the battery is replaced.
- Store the watch in a cool, dry place away from magnetic fields, extreme temperatures, and direct sunlight when not in use.
- Avoid exposing the watch to chemicals, solvents, perfumes, or cosmetics, which can degrade seals and damage the finish.
- If the bracelet becomes stiff or the bezel action feels rough, contact our service team for professional cleaning and lubrication.
