Each watch is individually tested to the pressure equivalent of being 300 metres underwater. In practical terms, this means it’s safe for all water activities, up to and including deep sea diving (though not with mixed gasses).

As with all watches, no. Hot water can cause rapid temperature changes that stress gasket seals. As the materials expand and contract, tiny gaps can form, so moisture finds its way inside. And anyway, why?

Swiss Super-LumiNova

Indices and the 12 o’clock marker on the bezel glow green, hands and bezel numerals are blue. We like the contrast for ultimate legibility in dark conditions.

The lume colours of the hands and indices are intentionally different. In some lights they both look white, in others they show a subtle difference in shade.

Ontic watches are designed, assembled and tested in the UK. Individual components are sourced internationally.

Our watches are powered by a Swiss solar movement that doesn’t need regular servicing. Under normal conditions, the movement will run for 10+ years without attention.

If you swim, dive, or fall into rivers often, we recommend having a qualified watchmaker test the seals and water resistance every two years. It’s a quick check that helps keep your watch properly sealed and performing as it should.

All watches are covered by a 3-year warranty. It covers movement issues arising from normal use, or any defects with manufacturing.

Full details are available in our warranty policy at the bottom of our Terms of Service

Contact us at support@onticwatches.com if you have a query or problem.

Yes. The movement and seals use standard Swiss components, so any competent watchmaker can handle routine servicing or replacements almost anywhere in the world.

Then it comes home. All complex repairs are done in Britain by the same team who built your watch, sometimes while muttering about your choice of activities.
