Product Features

600m Water Resistance - This watch withstands pressure equivalent to 600 metres underwater, making it suitable for professional diving, saturation diving and extreme water sports. The 60 bar rating exceeds most recreational diving requirements and provides confidence for serious underwater activities. ISO 6425 Certification - Meets strict international standards for diving watches including water resistance testing, shock resistance and magnetic field resistance. This certification guarantees the watch performs reliably in professional diving conditions and emergency situations where timing accuracy is critical. Automatic Helium Escape Valve - Prevents case damage during decompression in saturation diving by automatically releasing helium gas that penetrates the watch during deep dives. This technical feature is essential for commercial divers and protects the movement from pressure-related damage.
Ceramic Bezel Insert - The unidirectional rotating bezel features a ceramic insert that resists scratches, fading and corrosion from saltwater exposure. Ceramic maintains its appearance and functionality even after years of diving use, whilst the unidirectional rotation prevents accidental adjustment that could compromise dive timing. Powermatic 80 Movement - Swiss automatic movement provides 80 hours of power reserve, meaning the watch continues running for over three days without wearing. This extended reserve ensures reliable timekeeping during multi-day diving expeditions and reduces the need for frequent winding. Sapphire Crystal Glass - Scratch-resistant sapphire crystal protects the dial and maintains clear visibility underwater. This material ranks second only to diamond in hardness, ensuring the watch face remains readable even after contact with rocks, coral, or diving equipment during underwater activities.

FAQs

Is this watch suitable for professional diving?

Yes, the Tissot Seastar 2000 meets ISO 6425 certification standards for professional diving watches. With 600m water resistance and features like an automatic helium escape valve and unidirectional bezel, it's designed for commercial and technical diving applications including saturation diving.

How long does the power reserve last?

The Powermatic 80 automatic movement provides 80 hours of power reserve. This means the watch will continue running for over three days without being worn or wound, making it ideal for weekend storage or multi-day diving expeditions where consistent timekeeping is essential.

What makes the bezel special for diving?

The unidirectional rotating bezel features a ceramic insert that's virtually scratchproof and fade-resistant. It only rotates in one direction to prevent accidental adjustment that could lead to miscalculating dive time. The ceramic material maintains its appearance and markings even after extensive saltwater exposure.

Why does it need a helium escape valve?

During saturation diving, helium gas penetrates the watch case. When divers decompress, this gas expands rapidly and can damage the movement or pop off the crystal. The automatic helium escape valve releases this pressure safely, protecting the watch's internal components during professional diving operations.

How accurate is the timekeeping?

As a Swiss automatic movement, the Powermatic 80 typically maintains accuracy within -4/+6 seconds per day when fully wound and properly maintained. The movement features anti-magnetic properties and shock resistance to maintain precision even in demanding diving environments.

Can I wear this watch daily or just for diving?

Despite its professional diving capabilities, the Seastar 2000 is designed for everyday wear. The 46mm case size and comfortable rubber-fabric strap make it suitable for office wear, whilst the robust construction handles daily activities. The black dial and steel case offer a versatile appearance.

What type of strap does it come with?

The watch includes a black rubber and blue fabric hybrid strap that's waterproof and comfortable for extended wear. This strap material resists saltwater corrosion and remains flexible in cold water conditions. The 22mm width allows for easy replacement with other compatible diving straps.

How do I maintain the water resistance?

Ensure the screw-down crown is properly tightened before water exposure. Avoid operating the crown or bezel underwater. After saltwater use, rinse with fresh water and dry thoroughly. Have the seals checked by a qualified technician every 2-3 years to maintain the 600m water resistance rating.
