Ocean Crawler Core Diver - BlueShark 2025 LE — 44mm Automatic Dive Watch
About this watch
Design
The BlueShark dial sets the tone, framed by a sapphire unidirectional rotating bezel and set into a 44mm case in 316L stainless steel. At 44mm across, 15.6mm thick and 50mm lug-to-lug, it wears with real presence on the wrist.
Movement
Inside beats a Swiss-made Sellita SW200-1 automatic, running at 28,800 vph with roughly a 40-hour power reserve. It winds itself from the motion of your wrist — no battery, just a mechanical heart that has been individually regulated for accuracy.
In the water
Every Ocean Crawler is pressure-tested in water, and this one is rated to 600 metres (60 ATM). That is genuine capability for recreational and technical scuba diving, freediving and spearfishing. A helium escape valve lets it handle saturation diving and decompression chambers. The unidirectional bezel and bright Super-LumiNova keep elapsed-time tracking clear even in dark water.
Who it’s for
It is made for divers and enthusiasts who want a serious tool watch with genuine depth rating, Swiss-grade mechanics and a design that still turns heads above the surface.
New, boxed and warrantied — free US shipping.

It pairs 600 metres (60 ATM) of tested water resistance with a full sapphire bezel and sapphire crystal, a serious tool-watch build and Swiss Super-LumiNova, so it performs underwater and still looks refined on land.
What movement does it use?
A Swiss-made Sellita SW200-1 automatic running at 28,800 vibrations per hour with about a 40-hour power reserve. It is self-winding, so there is no battery to replace.

Yes. It is a brand-new, boxed Ocean Crawler backed by the maker 5-year warranty, with free US shipping and easy returns if it is not right for you.
Customer reviews
The BlueShark dial is deep and mesmerizing. 2000ft water resistance is insane overkill in the best way possible.
Despite being a serious tool watch, it looks dressy enough for the office when you swap it onto the leather strap. Fantastic piece.
The build quality is up there with Swiss brands that cost 3x as much. Just wish the clasp had a quick micro-adjust system. 4 stars.
Bought the BlueShark for his 30th birthday. He loves the heavy, quality feel of it and hasn't taken it off yet!
The 2025 edition totally nailed it. The lume is nuclear, the blue pops, and it comes with extra straps. 10/10.
