The watch
Built around an electric reef mantis dial, the Ocean Crawler Bolt - Electric Reef Mantis (Limited Edition) pairs a 42mm 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 Electric Reef Mantis dial sets the tone, framed by a sapphire unidirectional rotating bezel and set into a 42mm case in marine-grade 316L stainless steel. 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.

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 electric reef mantis 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.

Owners say
I hesitated before buying a $999 watch online, but the weight of the 316L steel bracelet and clarity of the 3.5mm sapphire crystal won me over right away. Knocked one star only because the screw-down crown threads are tight at first and take a firm push to catch.
I mostly collect mechanical chronographs and pilot watches, so I'm picky about rotating bezels and timing scales. The 120-click sapphire bezel on this Bolt Mantis snaps into place with zero play, and the SW200-1 keeps great time. Shipping carrier delayed the box by two days, though the watch itself is great.
Sorry the carrier held up your delivery, Luke! Glad that 120-click sapphire bezel met your standards once it arrived.
Sized the integrated stainless steel bracelet for my 7.5-inch wrist in ten minutes and wore it all week before trying the additional strap that comes in the box. Both options are super comfortable and give the Mantis dial two distinct looks.
Wasn't sure what to expect ordering a microbrand diver at this price, and the outer presentation box was fairly basic, though the watch is clearly where the money went. The solid 316L integrated bracelet, sapphire bezel, and Swiss SW200-1 movement are top notch.
Thanks for giving us a shot, Victor! We put every dollar we can into the 316L steel machining, sapphire bezel, and Swiss Sellita movement.
Measured the case at 42mm wide and 12.3mm thick, which is impressively thin for a 600m (60 ATM) rating. The 120-click sapphire bezel has zero backplay, the Sellita SW200-1 winds smoothly, and the C3 Super-LumiNova is bright and evenly applied.
I was a little nervous spending a thousand dollars online on a brand I hadn't handled in person, but the Bolt Electric Reef Mantis is the real deal. The solid links on the integrated bracelet, crisp case bevels, and 3.5mm AR sapphire crystal feel on par with my Swiss pieces costing twice as much.
That Mantis dial color is unreal in California sun. Fits my wrist great.
