Ocean Crawler Core Diver - BlueShark 2025 LE — 44mm Automatik-Taucheruhr

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.

On the ChronoSeasons dial it sits at Hour IV — Dive, part of the Expedition season, and suits swimming, sailing, beach travel and everyday wear.
