The Ironside 200: DeMarco's New Automatic Diver
DeMarco's Ironside 200 is a 200m automatic diver with a Seiko NH35 movement, sapphire crystal, and ceramic bezel. Here's what you need to know.

The Ironside 200 is DeMarco Watch Co.'s first serious diver, and it's built to back that up with real specs rather than just a rotating bezel and a hopeful attitude.
200m Water Resistance — What That Actually Means
The 200m (20 ATM) rating puts the Ironside 200 in genuine dive watch territory. That's not just splash-proof, not just shower-safe — it means swimming, snorkelling, and recreational scuba diving are all on the table. DeMarco even backs this with a waterproof warranty covering flooding within the two-year warranty period, which says something about how confident they are in the build.
The Movement
Inside is a Seiko NH35 automatic, which is the right choice for a watch at this price point. It's reliable, widely serviced, self-winding, and has been the backbone of affordable dive watches for years. You're not getting a Swiss movement at $399, but you are getting something that will run accurately and can be serviced almost anywhere.
Built for Low Light
The Ironside uses Super-LumiNova BGW9 lume — the blue-tinted variety that glows a bright blue-green in the dark. On a dive watch this matters. Whether you're underwater or just checking the time at night, the indices and hands are legible without squinting.
The Bezel
A 120-click unidirectional ceramic bezel. The 120-click action gives you precise elapsed-time tracking, and ceramic resists scratching far better than aluminium inserts. On a diver, the bezel takes more abuse than almost any other part of the watch, so this is the right call.
Sapphire Crystal with AR Coating
The crystal is sapphire with anti-reflective coating. Again, this is the right spec for a diver — sapphire is far harder than mineral glass and resists the kind of knocks a dive watch accumulates over time.
The Bottom Line
The Ironside 200 is a well-specced automatic diver at a price that makes sense. Seiko movement, sapphire crystal, ceramic bezel, 200m rating, lume that works — it ticks every box for an everyday wearable dive watch. Available on Kickstarter now for $399, with a retail price of $599 once the campaign closes.
