Blue and orange contrast
The blue and orange colors on this Core Diver give it a really cool, almost retro sports vibe. 44mm case is super tough and legible.
The watch
Ocean Crawler Core Diver - Blue/Orange: a blue/orange-dial dive watch in a 44mm 316L stainless steel case, driven by a Swiss automatic Sellita SW200-1 movement. It brings 600m water resistance and a sapphire crystal. On the ChronoSeasons dial it sits at Hour IV — Dive, part of the Expedition season — and suits swimming, sailing and beach travel.
The Blue/Orange 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.
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.
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.
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.

Good to know
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 blue/orange 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.

I waited a bit for this one and it didn't disappoint. Tested to 2000ft water resistance, it's totally over-engineered and I love it.
It has some serious weight to it. 4 stars because the bracelet took a bit of effort to size correctly, but now it feels like armor on my wrist.
She bought it for our beach vacation. The orange accents totally pop in the summer sun. Kept perfect time the whole trip.
If you want a diver that isn't just another black-dial clone, the blue and orange Core Diver is a breath of fresh air. Excellent quality.
