Ocean Crawler Core Diver - White Mother of Pearl - Carbon Fiber Bezel

Ultra-Black — deepest blackness, strong impact

The new Ultra-Black dial relies on an almost dramatic look: a special color that over 99,4 % absorbs the light, creating a “black hole” effect that makes the dial appear like a deep, endless surface. Each piece thus appears individual — perception changes depending on ambient light, and that is exactly what makes the limited edition of each 100 numbered watches per color variant so special.

Design & readability

Despite the extremely dark surface, readability was not left to chance: large indices and high-contrast contrasts ensure the time remains immediately recognizable. Combined with strong luminous material on critical areas, this creates an appealing tension between an almost invisible dial surface and clearly visible functional areas — a look that captivates visually and works practically. Depth and contrast are the design principles here.

Case construction and surfaces

The case made of 316L stainless steel comes with a DLC coating that intensifies the look and increases durability; brushed surfaces give the body a technical appearance, polished edges add fine accents. The construction is deliberately designed for rugged use and features such as screw-down crowns and a helium valve, demonstrating: function takes precedence over form here — without compromising aesthetics. Robustness meets form.

Sapphire crystal and bezel

An exceptional feature is the bezel made entirely of sapphire, unidirectional with 120 clicks, and a 4.0 mm thick sapphire crystal: this combination provides extreme scratch resistance and clear underwater visibility. The hour markers on the bezel as well as the essential scales are filled with multiple layers of Swiss C3 luminous material, ensuring immediate and lasting readability during deep dives.

Depth reserves and test bench

The Core Diver is designed for tough missions and individually tested; the water resistance is rated for 600 m (approx. 2000 ft) and each watch has undergone water resistance and pressure tests that far exceed normal recreational diver requirements. Therefore, the model is suitable for both scuba and technical dives as well as demanding activities like spearfishing or seabed research. Reliability is lived here.

Drive and accuracy

Inside works a regulated Sellita SW200-1, a proven Swiss automatic movement with 28,800 vibrations per hour and about 40 hours power reserve. Factory fine regulation has optimized accuracy so the watch runs precisely for demanding use — an important criterion when it comes to navigation and timing under difficult conditions. Precision is the program.

Straps and clasp

Each watch is delivered with two strap options: a DLC-coated shark mesh bracelet with ratchet extension for secure hold over the diving suit and a robust, finely crafted rubber strap for maximum comfort in the water. The clasp allows fine adjustments so the watch sits on the wrist without slipping — a detail that makes a big difference in practice. Flexibility and safety are paramount.

Operation under extreme conditions

All controls are designed to be easy to handle even with gloves or underwater: the bezel engages firmly, the crown screws down securely, and the helium valve ensures pressure equalization during saturation dives. Taken together, this results in a watch that is understood more as a working tool in practical use than as a mere piece of jewelry. Usability is the promise.

Limitation and collector character

The strictly limited, numbered editions make each watch a collector's item: anyone owning one of the 100 pieces per variant holds not only a technical instrument but also a signed piece of a conscious, exclusive edition. This increases the emotional value alongside the purely functional benefit — making the watch especially attractive to enthusiasts. Exclusivity is tangible.

Conclusion — who this watch is for

The Ultra-Black-Core-Diver is aimed at people looking for an uncompromising dive watch that also dares a strong, distinctive design: technically well thought out, high-quality in manufacturing, and dramatically dark in effect. Whether professional divers, adventurers, or collectors with a taste for the unusual — this watch combines technology and aesthetics in a way that impresses equally underwater and on land.
