The Depthmaster has always been about a simple idea: when the environment gets serious, the watch must stay clear, stable, and uncompromising. Not louder. Not shinier. Just built to do the job.
This Nivada x Ocarat edition pushes that logic further by starting where most “limited editions” stop: with the material itself. The dial is made from blue fossilized coral, a natural element shaped by time and pressure, then cut and finished into a surface that can’t be replicated. No two patterns match, no two textures land the same, and that’s exactly the point. Each piece carries its own signature, like a fragment of the sea turned into a tool.
Around it, everything stays faithful to the Depthmaster’s purpose. The 39mm cushion case in 316L steel keeps a compact, confident stance on the wrist, while the matte brushed/satin finishing avoids unnecessary reflections. The unidirectional bezel is there for timing, not decoration. The flat sapphire crystal keeps the view clean and direct. And the architecture is backed by the essentials that actually matter underwater: screw-down crown, screw-down caseback, and a rating that speaks for itself, 100 ATM / 1000m.
Inside, the watch stays equally pragmatic. The Swiss automatic Soprod P024 brings dependable, everyday performance with a 38-hour power reserve, driving a legible three-hand display designed to be read fast, in motion, and in low light.
Limited to 50 numbered pieces, this edition isn’t trying to reinvent the Depthmaster. It simply gives it a dial that makes the story tangible: a material born from the ocean, placed into a case engineered to resist it.
