How it works
What this watch’s key specs actually mean on the wrist.
Automatic
Automatic (self-winding) movement
A weighted rotor spins as your wrist moves, winding the mainspring so the watch never needs a battery. The seconds hand sweeps in a smooth glide rather than ticking. Wear it regularly and it keeps running; set it down for a day or two and you simply give the crown a few winds. It is the traditional, collectible heart of mechanical watchmaking.
100m / 10 ATM
Water resistance
Rated to 100m / 10 ATM — genuinely swim-ready. Laps, snorkeling and a day at the beach are all no problem; it just isn't a scuba watch.
41-hour reserve
Power reserve
Fully wound, this movement stores about 41 hours of running time when it's off your wrist. Enough to comfortably carry it overnight without resetting the time. Power reserve is simply how long the mainspring keeps the watch going once you stop wearing it.
42.5mm
Case size
The case measures 42.5mm across (excluding the crown) — a modern, present size with real wrist presence, at its best on medium-to-larger wrists. Case size is the single biggest factor in how a watch actually wears, so it's worth picturing against your own wrist.
Stainless steel
Case material
Stainless steel is the all-rounder for good reason: tough, corrosion-resistant, and easy to refinish if it ever picks up a scratch. 316L is the marine-grade alloy used across quality watchmaking — durable enough for daily life and smart enough to dress up.
