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

The Aquatic Core Diver Collection celebrates life underwater with two expressive color variants — Mandarin fish and Blue Shark — each strictly limited to only 100 numbered pieces per color. This special edition combines uncompromising diving capability with a clearly visible design approach that not only depicts the beauty of the seas but reflects it in every detail.

Color scheme and inspiration

The color choice is directly inspired by sea creatures: one model adopts the warm, radiant palette of a mandarin fish, while the other relies on the cool, powerful presence of a Blue Shark. These colors are not just coatings but are coordinated so that the dial, bezel, and strap harmoniously blend and reveal a new nuance with every wrist movement.

Case & materiality

The robust case made of 316L stainless steel stands for functionality and durability; with a diameter of around 44 mm, a height of 15.6 mm, and a lug-to-lug measurement of approx. 50 mm, the watch wears like a serious instrument that also values artisanal surface finishing. The brushed surfaces emphasize the material quality, while polished edges deliberately set accents.

Sapphire crystal and bezel

A special feature is the bezel made entirely of sapphire along with the sapphire crystal: the unidirectional rotating bezel is scratch-resistant and features hour markers filled with multiple layers of luminous material — an approach that meets the highest standards both visually and functionally. The thick sapphire crystal is highly robust and coated with an anti-reflective layer to ensure clear visibility underwater.

Luminosity and Readability

For depth displays, seven positions of Swiss C3 were used, so the most important markers and scales remain immediately visible even in complete darkness; this Swiss C3 treatment ensures reliability in critical moments and increases safety while diving. Color contrasts and large indices additionally support quick orientation.

Drive and precision

Inside works a regulated Sellita SW200-1, a proven Swiss automatic caliber with 28,800 vibrations per hour and about 40 hours power reserve. The movement regulation aims at improved accuracy, so the watch functions as a reliable companion in everyday use and on longer expeditions.

Depth resistance and tests

The Core Diver has been individually tested and is designed for real use up to 600 m (approx. 2000 ft / 60 ATM); each piece undergoes water pressure tests that exceed normative requirements and features a helium valve solution at nine o'clock for saturation dives. These test series justify the claim to position the watch as a serious tool for divers and marine researchers.

Straps & clasp

Each watch is delivered with two wearing options: a solid link bracelet with ratchet extension clasp for secure adjustment over a wetsuit and a specially made stingray rubber strap, which is both tactile and functionally tailored for rough use. This combination allows the watch to be adapted in no time to any activity and style.

Handling, presence, and everyday use

With a clear, striking presence on the wrist, the Core Diver is also designed so that operation and reading underwater are quick and intuitive; the dimensions and ergonomic case shape balance visual impact and wearing comfort. For practical use, all controls and surfaces are designed to be safely handled even with gloves.

Conclusion

The Aquatic Core Diver Collection is more than a visual statement: it combines technical substance, tested diving suitability, and a very targeted, natural color palette. In the limited edition of 100 numbered pieces per color variant, this edition appeals to both passionate divers and collectors who value a watch that performs underwater as impressively as it does above the surface.
