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.

500m / 50 ATM

Water resistance

Rated to 500m / 50 ATM — serious professional-diver territory. This is far more depth than daily life will ever ask of it, which is exactly the point: total peace of mind around water.

Nick the owner was very attentive in answering my questions regarding the delivery of the watch. I didn’t realize I ordered it from somewhere international, but nonetheless it arrived with no issues perfectly packaged. Thanks Nick!
