The D-1 is your daily driver, and like the perfect pair of jeans, is comfortable just about anywhere. Like all our watches, it’s made in Switzerland and is powered by an automatic Elabore grade Sellita movement with a 38-41 hour power reserve, chosen for its reliability in all conditions. A tool watch through and through, its case is made from durable 904L stainless steel, which is known for its anti-corrosion qualities. It is a far more durable alloy than the regular 316L steel more commonly used in the industry, and while it’s more difficult to mill, the extra effort was worth it. In short, it can take a beating and will look even better with a little wear and tear. Life has a habit of throwing the occasional curveball. The D-1 can take it.
We retain our signature one-piece dished dial, which curves up around the edges, meeting the bottom of our domed sapphire crystal glass. It gives the case a satisfyingly curved, pebble-like silhouette. We spent more time perfecting the angle of the lugs, too. This ensures the D-1 hugs the wrist, combining with our integrated straps to ensure day-long comfort.
The circular brushed case finish perfectly complements the unidirectional satin-finished ceramic bezel, which rotates with a satisfying ‘click’. If you’re counting, a full rotation takes precisely 120 clicks. Diving watches have long been appreciated for their functionality and rugged appeal. The D-1 is no different. It’s more than capable of being used as a tool for regular deep dives, but it’s just as at home under a shirt cuff on dry land. It comes with a screw down crown and a 300m water resistance, which is further improved thanks to the new case back, secured with six visible screws for a utilitarian look.
Available in an edition of 300, Included with every purchase are two of our integrated straps which come with matching brushed 904L steel hardware. The D-1 Diver comes on a Scuba Black FKM Rubber as well as an additional strap, which can be chosen from a pre-selected range. They form perfectly around the wrist thanks to our ergonomically designed lugs, and feature our quick-release spring bars, so you can change the look of the D-1 on the fly, wherever your mood takes you.
