The watch
Built around an arctic blue dial, the Ocean Crawler Core Diver V4 - Arctic Blue pairs a 44mm case with a Swiss automatic Sellita SW200-1 movement. Highlights include a limited production run, 600m water resistance and a sapphire crystal. It belongs to Hour IV, Dive, in our Expedition season: a natural choice for swimming, sailing and beach travel.
The Arctic Blue 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.
New, boxed and warrantied — free US shipping.
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 arctic blue 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.
On the ChronoSeasons dial it sits at Hour IV — Dive, part of the Expedition season, and suits swimming, sailing, beach travel and everyday wear.
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.
From the journal
Owners say
Did a wreck dive off the Carolina coast with the V4 Arctic Blue on the rubber strap. Even at 85 feet in murky water, the high-contrast hands and C3 lumed bezel were effortless to read, and the crown locks down tight.
Added the V4 Arctic Blue to a 12-watch box dominated by Swiss divers. At 44mm across and 15.6mm thick with a helium escape valve and 600m rating, it is a serious chunk of 316L steel for my wrist. The Sellita SW200-1 is running +3.5 sec/day and the 120-click C3 sapphire bezel is super crisp. Knocking one star only because the shipping carrier delayed the box by two days, though the watch itself is great.
Hi Ralph, sorry the carrier held up delivery by a couple of days! Glad the V4 Arctic Blue is earning its spot alongside your Swiss divers.
I own earlier Core Diver generations, and the V4 Arctic Blue is my favorite execution yet. The 44mm by 15.6mm 316L case sits flat on my 7.25-inch wrist thanks to the compact lug-to-lug, and the 4.0mm AR sapphire crystal keeps the icy dial distortion-free. The 120-click lumed sapphire bezel has crisp detents with zero play, and the Sellita SW200-1 inside is holding +2 seconds per day.
Took this out on my center console off Montauk all weekend. Between the 600m water resistance, screw-down crown, and bright C3 Super-LumiNova on the sapphire bezel, it is a serious ocean tool watch that laughs at salt spray.
Been wearing this for two weeks now. The Arctic Blue dial has a cool metallic frost in real sunlight that photos don't quite show, and on the rubber strap it wears very comfortably on my wrist.
Picked up the V4 Arctic Blue for my younger brother to wear at his coastal wedding in Maine. He loves dive watches and the icy blue dial matched the wedding colors without looking cheesy. He wore it through the ceremony and on his honeymoon.
I hesitated before spending a grand on a brand I only knew from watch forums, but the V4 Arctic Blue won me over the second I unboxed it. The solid shark-mesh bracelet, 4mm sapphire crystal, and crisp C3 lume bezel feel like a watch costing twice as much.
Arctic Blue dial looks sharp in daylight. Fits my wrist comfortably.
