UTILITY 40 | DIVE COLLECTION | MARINE
The DIVE collection takes our function-first philosophy and fine-tunes it for the deep.
It’s a proper dive watch: 300 metres of water resistance, corrosion-proof TiX titanium, screw-down crown, and crystal-clear clarity when visibility drops. Built to stay calm under pressure, much like the people who wear it.
Fitted with a high-contrast unidirectional bezel designed for total legibility when timing dives (and, let’s be honest, cooking pizza).
Built with the same function first mindset as every Ontic, it’s ready for cold currents and murky depths, but looks pretty sharp on dry land too.
Designed, assembled and tested in Britain. Supported for the long term.

TECHNOLOGY
SWISS SOLAR QUARTZ
At the heart of the UTILITY 40 is the Swiss-made Ronda Solartech 215. It’s a solar-powered quartz movement built for accuracy, longevity, and sheer stubborn reliability.
Quartz is the logical choice for a proper tool watch. It keeps time to within seconds a month, shrugs off shocks, and never needs winding. When you’re relying on your kit, precision and simplicity matter more than ritual.
Solar power takes that reliability even further. Light from almost any source charges a lithium cell beneath the dial, giving up to eight months of run time in complete darkness. No batteries to change, no waste, no fuss. Just a watch that quietly minds its own business.
TECHNOLOGY
TiX TITANIUM
The case of the UTILITY 40 is made from TiX. That’s the name we give to our specification of hardened titanium.
Starting with Grade 2 titanium, we add a diamond-like carbon surface that forms a dense outer layer roughly four times harder than steel, giving the case outstanding scratch resistance without adding weight. It’s not paint, it’s not plating, and it won’t wear off.
The result is a hypoallergenic and corrosion-proof material that’s 4x harder than steel yet 40% lighter.
That’s what makes the UTILITY 40 lighter than it looks, tougher than it needs to be, and calmly unimpressed by whatever you do to it.

TECHNOLOGY
DESIGNED, ASSEMBLED & TESTED IN THE UK
Every Ontic starts life on a British workbench. Designed, assembled and tested here by people who care about doing it right. It’s slower, pricier and occasionally involves swearing, but it guarantees each watch leaves the bench properly built and properly tested.
Each watch is tested for water resistance, accuracy, and finish before it leaves. No conveyor belts, no jazzy robots, just patient watchmakers who want to do it right.
Once it’s on your wrist, the same team who built it will support it for life.
British-built. World-ready. And proudly allergic to shortcuts.
