Ocean Crawler Decompression Timer Core Diver - Black DLC — 44mm Automatic Dive Watch
The watch
Built around a black dial, the Ocean Crawler Decompression Timer Core Diver - Black DLC pairs a 44mm case with a Swiss automatic Sellita SW200-1 movement. Expect 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 Black dial sets the tone, framed by a sapphire unidirectional rotating bezel and set into a 44mm case in 316L stainless steel with black DLC coating. 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 black 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.

Owners say
Bought the Black DLC Decompression Timer for my brother's 40th birthday before his dive trip to Cozumel. He loves vintage-style decompression dials and was blown away by the 600m rating and the two included straps.
This was my first purchase outside the big Swiss brands and I had some doubts before opening the package. Between the smooth Sellita SW200-1 sweep, the heavy shark-mesh bracelet, and the crisp printing on the decompression dial, I am completely sold.
I wear a lot of black and charcoal studio attire, and the Black DLC case with the colorful decompression rings fits my style well. Works nicely on my wrist. Lume is decent for a few hours, though not an all-night torch.
I wasn't sure what to expect from a $999 DLC watch ordered online, as cheap black coatings scratch easily. After a month of wear, the DLC case and 4mm sapphire look brand new. The extra strap was pretty stiff for the first 3-4 days before breaking in.
Hi Vance, our black DLC coating is hardened to shrug off everyday wear and tear! Glad it's holding up great for you.
Measured the DLC case at 44mm by 15.6mm. The black coating is uniform, the helium valve sits flush, and the 120-click sapphire bezel aligns dead on with zero play. Decompression tables on the dial are printed sharply under the 4mm sapphire.
The colorful decompression stops printed across the matte black dial give this 44mm Black DLC Core Diver a true 1960s saturation-diver vibe. At 15.6mm thick with a 4.0mm AR sapphire crystal and helium escape valve at nine, it has serious wrist presence on my wrist without overhanging. The 120-click C3 lumed sapphire bezel locks in tightly, and the Sellita SW200-1 has been running +1 second per day over two weeks.
