How it works

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

Solar

Solar-powered movement

A solar cell under the dial turns any light — sunlight or a desk lamp — into power and stores it in a cell that lasts for months in the dark. You get quartz accuracy with no battery changes to think about, ever.

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.

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.
