Delma Oceanmaster Lume Review: Triple-Lume Sailing Watch with BGW9, C1, and Full-Lume Dial
Delma Oceanmaster Lume: A Triple-Lume Sailing Watch That Glows in Every Color
Delma has expanded its Oceanmaster sailing watch collection with the Oceanmaster Lume, a model that takes luminous materials to new extremes by combining three different types of Super-LumiNova across its dial, hands, and indices. Released in January 2026, this sailing-oriented sports watch features fully luminous dials available in blue, green, yellow, and orange, plus a limited-edition white-dial version honoring Swiss professional sailor Oliver Heer.
According to aBlogtoWatch, the Oceanmaster Lume's blue dial model uses turquoise Super-LumiNova across its entire surface for a matching blue glow, while the hands receive green-glowing C1 Super-LumiNova for contrast. The applied hour markers are filled with BGW9 Super-LumiNova, which appears white in daylight but emits an aqua blue glow in darkness — creating a multi-layered luminous experience unlike any other watch in its price range.
Understanding the Triple-Lume System
The Delma Oceanmaster Lume is a masterclass in combining different luminous compounds for maximum visual impact and functional differentiation:
| Component | Lume Type | Daylight Color | Glow Color |
|---|---|---|---|
| Dial Surface | Turquoise Super-LumiNova | Colored | Blue (matching dial) |
| Hands | C1 Super-LumiNova | White | Green |
| Hour Markers | BGW9 Super-LumiNova | White | Aqua Blue |
This deliberate mix of lume types ensures that the watch remains legible in darkness despite having a fully luminous dial. The different glow colors create visual separation between the time-telling elements and the background.
Built for Sailing, Rooted in Diving
While the Oceanmaster Lume is designed for competitive sailing, its 44mm stainless steel case delivers 500 meters of water resistance — borrowed from Delma's Shell Star dive watch collection. The case features a signed screw-down crown, domed sapphire crystal with anti-reflective coating, and a display caseback showcasing the Sellita SW200-1 automatic movement.
The dial includes "tactical planner" indicators — red and blue shapes with a horizontal dividing line — that help sailors plan routes and navigate changing wind conditions. A nautical-scale bezel with compass markings complements these sailing-specific features.

Frequently Asked Questions
Q: What's the difference between C1 and BGW9 Super-LumiNova?
A: C1 emits a green glow and is typically brighter initially but fades faster. BGW9 emits an aqua blue glow and retains its glow longer, making it ideal for hour markers that need sustained visibility.
Q: Is the Delma Oceanmaster Lume suitable for actual diving?
A: With 500m water resistance, a helium escape valve, and a unidirectional bezel, the Oceanmaster Lume exceeds the requirements for recreational and professional diving — though it was designed primarily for sailing.
Q: How does the fully luminous dial affect legibility?
A: Delma addresses this by using contrasting lume colors (green hands against blue dial) to ensure the time-telling elements remain distinct from the glowing background.
