Seac Chronos – The only truly waterproof chronometer for freedivers and water sports enthusiasts

If you're a freediver, diver, swimmer, or water sports enthusiast, you know the problem: there are no truly waterproof stopwatches! Most models advertised as "waterproof" are actually only splash-proof or suitable for short-term water exposure. Many electronic stopwatches fail after just a few uses in water due to leaks, condensation, or corrosion.

The Seac Chronos is different: it’s not just a stopwatch, but a fully waterproof chronometer that works reliably even underwater. With a guaranteed waterproof rating up to 100 meters, it withstands pressure even at greater depths – perfect for freedivers, scuba divers, swimmers, and anyone who needs precise time measurement in the water.

Why choose Seac Chronos for water sports?

• 100% waterproof up to 100m – not just splash-resistant, but truly waterproof.
• Reliable stopwatch function – ideal for measuring dive times or training intervals.
• Compact and durable design – resistant to water, pressure, and impact.
• Easy to use – works even with wet hands or a neoprene wetsuit.
• The most affordable waterproof time measurement – the best alternative to expensive dive computers or unreliable watches.

For freedivers, precise time measurement is essential – whether for static training (STA), interval exercises, or surface interval tracking. While dive computers offer more features but at a much higher cost, the Seac Chronos is the most budget-friendly way to measure your underwater time.

Swimmers, triathletes, and other water sports enthusiasts will also find this chronometer useful. Whether for training, competition, or simply tracking performance, the Seac Chronos helps you stay in control.

The Seac Chronos is not a dive computer

The Seac Chronos waterproof chronometer is a watch with a stopwatch function, designed for use both above and below water. However, it is not a dive computer or freediving computer and does not measure depth. If you're looking for an affordable freediving computer, check out the Seac Partner!
