The Neptune was designed for those who operate in the depths and carry themselves with quiet confidence on the surface. Born from the vision of a Marine Raider, it is a combat diver’s watch with the clean lines of a gentleman’s timepiece, a blend of rugged intent and refined execution.

From the start, the Neptune was shaped by input from the people who would actually wear it. With over 300,000 man-hours of use and feedback from 60 veterans, active-duty service members, and technical experts, it reflects what the Sangin community asked for: slim, functional, and built to perform in the real world.

At just 11mm thick, the Neptune wears comfortably under a cuff or over a wetsuit, something few 300-meter dive watches can claim. The crown is positioned at 8 o'clock within an integrated crown guard due to the asymmetrical case; A subtle but intentional choice to reduce wrist interference during dynamic movement while increasing protections for the crown, especially when you are on the go or carrying gear.

Inside, the Swiss Sellita SW300 movement keeps the Neptune running with smooth reliability, offering a 56-hour power reserve and an in-house regulated accuracy of +/- 5 seconds per day in four positions. It is a movement trusted to stay on time, even when everything else is chaos.

Legibility was another non-negotiable. The Neptune features Super-LumiNova BGW9 for lasting glow in low light, paired with a double-domed sapphire crystal that is coated to reduce glare while enhancing clarity from every angle.

When it comes to the elements, the Neptune is built from corrosion-resistant 316L stainless steel, chosen for its resilience in both marine and urban environments. It is water-resistant to 300 meters and ready for tactical dives in saltwater, heavy surf, or wherever else the day leads.

Every choice, from the specs to the silhouette, reflects the core belief that you should not have to choose between performance and style. The Neptune delivers both. And like the community that helped shape it, it is built with quiet confidence, unshakable intent, and always With You™.
