The watch
Built around a blue dial, the Ocean Crawler Bolt DLC - Blue pairs a 42mm case with a Swiss automatic Sellita SW200-1 movement. Expect 600m water resistance and a sapphire crystal. We place it at Hour IV (Dive) of the Expedition season, for water sports and everyday wear.
The Blue dial sets the tone, framed by a sapphire unidirectional rotating bezel and set into a 42mm case in marine-grade 316L stainless steel with black DLC coating. At 42mm across, 12.3mm thick and 48mm 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. 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 42mm (12.3mm thick) — a mid-to-large size that suits average and larger wrists (roughly 16.5 cm / 6.5 in and up). Our watch size guide (/pages/watch-size-guide) explains how to measure your wrist.
It has a 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.
Yes. Other versions we carry include the Ocean Crawler Bolt DLC - Red, the Ocean Crawler Bolt DLC - Full Lume. 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.
From the journal
Owners say
I'm picky about surface coatings and edge chamfers. I was skeptical before opening the box, but the black DLC application across the integrated steel links and 42mm case is flawless, and the 3.5mm AR sapphire crystal is crystal clear.
Getting a thumbs-up from a machinist on our case chamfers and DLC finish means a lot, Jacob! Thank you.
Bought the Bolt DLC Blue for my son's 40th birthday up. He's hard on his watches and wanted a scratch-resistant black DLC bracelet with a Swiss automatic inside. He put it on immediately and loves the blue dial.
Happy 40th to your son, Steve! That black DLC coating is built to handle decades of daily wear.
Even with a black DLC finish, the 12.3mm slim profile and angular integrated bracelet let me wear this with a navy blazer and charcoal slacks to meetings. Slides right under a button-down cuff and the blue dial really pops.
Appreciate the review, Sam! Black DLC with a navy blazer is a sharp combo.
Fits my wrist great. Slight rotor whir in a dead-quiet room, which is normal.
Thanks, Ross! Glad the 42mm Bolt DLC Blue fits your wrist so well.
Wasn't sure how durable or refined a black coated bracelet would feel at this price, but the DLC finish on this 316L steel case is deep and even. My only minor gripe is the clasp lacks half-links, so the fit is slightly snug in humid Boston summer weather.
The matte black DLC coating and high-contrast blue dial give this Bolt a stealthy aviation-instrument look that I love. The 120-click lumed sapphire bezel is super crisp for timing, and the Swiss SW200-1 automatic hasn't missed a beat.
Got this 42mm Bolt DLC Blue for my older brother's 30th birthday. He wanted a blacked-out automatic watch that wouldn't scratch easily, and the marine-grade DLC coating paired with the blue dial and Swiss Sellita movement knocked his socks off.
Picked up the Bolt DLC Blue for my son when he made Chief in the Navy. The black DLC coating over the 316L steel with that bright blue dial looks tough as nails. The bezel action was a little stiff out of the box before working it around a few times, otherwise perfect.
