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.

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.
