How it works

What this watch’s key specs actually mean on the wrist.

Quartz

Quartz movement

A battery sends current through a quartz crystal that vibrates exactly 32,768 times a second, which the watch counts to keep time to within seconds a month — more accurate than almost any mechanical watch. Grab-and-go reliable: no winding, low maintenance, and years between battery changes.

200m / 20 ATM

Water resistance

Rated to 200m / 20 ATM — a true dive-capable rating. It handles swimming, snorkeling and recreational scuba diving without a second thought.

Carbon

Case material

Carbon composite is extremely light and shock-absorbing, with a marbled, high-tech look where no two cases are exactly alike. It brings serious-sports-watch DNA without the weight of metal.

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!
