Ocean Crawler ad: Black November: Save $300

That orange hand isn’t counting seconds. It’s keeping someone else’s time. Set it once to wherever the people you deal with are, and you stop working it out in your head. Every Core Diver GMT is immersed and pressure-tested to 600 meters before it ships. Not the model. The one in your box. 4mm of sapphire over the dial, a sapphire bezel above that, and a helium valve in the case. So it’s built to wear every day, not sit in a drawer. No battery inside. It winds itself as you wear it, which is how a watch like this ends up on a second wrist decades from now. Swiss Super-LumiNova on the hands, markers and bezel. Glows green in the dark, so you’ll never need to light a phone to check the time. $1,499 through Black November, down from $1,799. Split it into monthly payments with Shop Pay at checkout. Four colorways, 100 numbered pieces of each. 10,000+ owners. 3,200+ reviews. 4.8 stars. 5-year warranty. 30-day returns.
