Delma Launches Oceanmaster Lume: A Dive Watch That Lights Up the Night

In the world of high-performance dive watches, Delma has once again made waves with the launch of the Oceanmaster Lume, a timepiece that redefines visibility, precision, and durability. This fully luminous dive watch is not only a visual spectacle but also a testament to Delma’s unwavering commitment to innovation in the marine and sailing world.

This release makes a great addition to our affordable summer watches guide, especially for those seeking high-performance and standout visibility at an accessible price.

A Bold Evolution in the Oceanmaster Series

Delma’s Oceanmaster collection has long stood as a benchmark for nautical precision, and the new Lume edition pushes this legacy forward. Inspired by the intense conditions faced during professional sailing races, including its debut with Oliver Heer Ocean Racing, the Oceanmaster Lume is designed to thrive in the most extreme environments. It integrates legacy design with future-focused enhancements that cater to modern adventurers.

The Oceanmaster Lume distinguishes itself with a dial that’s entirely coated in Super‑LumiNova, offering unmatched visibility in darkness and underwater. Available in striking hues (blue, green, orange, and yellow) each version glows vividly, making it both a functional tool and a bold aesthetic statement. Whether navigating rough seas at night or diving deep beneath the surface, readability is never compromised.

Among the standout variants in the release is the Oceanmaster Oliver Heer Ocean Racing Limited Edition. Created to celebrate Delma’s partnership with Swiss skipper Oliver Heer during the 2024 Vendée Globe, this special edition combines the full-lume technology with a nod to professional ocean racing.

Engineered for Extreme Marine Environments

Built with professional-grade specs, the Oceanmaster Lume boasts a 500-meter water resistance rating and a helium escape valve, making it suitable for saturation diving. Its unidirectional nautical bezel incorporates a 360° tactical planner and points-of-sail indicators—tools especially useful for competitive sailors and offshore navigators. This level of functionality sets it apart from standard dive watches.

The Oceanmaster Lume is as robust as it is refined. Housed in a 44 mm stainless steel case, with a thickness of 13.8 mm and a lug-to-lug span of 51 mm, it offers a strong wrist presence without sacrificing comfort. The scratch-resistant sapphire crystal ensures long-lasting clarity, while a transparent caseback reveals the meticulously assembled Swiss movement inside.

Powering the watch is the reliable Sellita SW200-1 automatic movement, which features a 41-hour power reserve, hacking seconds for precise time setting, and a clean date display positioned at 6 o’clock. It’s a movement known for its dependability, blending performance with traditional craftsmanship.

The Delma Oceanmaster Lume is available now through Delma’s official channels and authorized retailers worldwide. Priced at approximately USD 1,650, EUR 1,500, or CHF 1,350, it offers substantial value for a watch of its caliber and capabilities.
