Ocean Crawler Core Diver - BlueShark 2025 LE — 44mm Automatic Dive Watch

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.

It is rated to 600 metres (60 ATM) and pressure-tested, so it is suitable for recreational and technical scuba diving, freediving and spearfishing. Have the gaskets checked periodically to keep that rating.

The case measures 44mm (15.6mm thick, 22mm lug width) — a bold size that suits larger wrists (roughly 17.5 cm / 6.9 in and up). Our watch size guide (/pages/watch-size-guide) explains how to measure your wrist.

It has a blueshark dial, framed by a sapphire unidirectional rotating bezel, under an anti-reflective sapphire crystal.

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.

The bezel and key dial markers carry Swiss Super-LumiNova, so elapsed-time tracking and reading the time stay clear in dark or murky water.

Availability changes with stock, so the collection page always shows what is in stock today.
