D-1 Ocean

Price Tier N/A

At 44mm, the D-1 Ocean has the presence of a professional diving instrument, balanced by a refined case profile designed for comfort and wearability throughout the day. | Its signature one-piece dished dial curves upward beneath the domed sapphire crystal, creating the smooth, pebble-like silhouette that defines the D-1 collection. The angled lugs and integrated strap system have been carefully refined to help the watch hug the wrist naturally, improving balance and long-term comfort. | Inside is an upgraded Swiss-made Sellita SW200-1 Elaboré automatic movement with a 38–41 hour power reserve, selected for its reliability, precision and long-term serviceability. Each watch is Swiss made and hand assembled by skilled artisans before final testing and quality control. | The case, bezel, buckle and case back are machined from brushed 904L stainless steel — chosen for its superior corrosion resistance and deeper lustre compared to industry-standard steels. More difficult to machine and finish, 904L requires additional time and precision, but the result is a case designed to wear beautifully over many years of use. | The satin-finished ceramic bezel rotates with a precise 120-click action, while the screw-down crown and updated six-screw case back help ensure 300m water resistance and add a more utilitarian feel. | Designed as a true modern tool watch, the D-1 Ocean feels equally at home underwater or on dry land — built for regular use and designed to wear beautifully over time. | Over time, it is designed to become familiar in the best possible way — a watch reached for instinctively, worn often and relied upon daily. | Produced in an edition of 300 pieces, each D-1 Ocean comes fitted with an Arctic White FKM rubber strap alongside a second integrated strap selected from a curated range. Both feature brushed 904L steel hardware and quick-release spring bars, allowing the watch to adapt easily to different environments and occasions.
