Ocean Crawler Field Crawler - Black — 40mm Automatic Field Watch
About this watch
Design
The Black dial sets the tone, set into a 40mm case in 316L stainless steel measuring 12.6mm thick with a 46mm lug-to-lug. A fixed bezel and sapphire crystal keep the Field Crawler clean, legible and ready for the trail.
Movement
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.
Water resistance
Rated to 400 metres (40 ATM) of water resistance, the Field Crawler shrugs off rain, rivers and open-water swims. As a field watch it is built for surface adventure — hiking, travel, snorkelling and everyday wear — rather than saturation diving.
Who it’s for
The Field Crawler suits explorers and everyday adventurers who want one rugged, good-looking automatic that moves from trail to office without missing a beat.

What movement does it use?
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.

Customer reviews
The 40mm Field Crawler in black is exactly what I needed. Tough, under the radar, and a crazy 40 ATM water resistance for a field watch.
The high contrast black dial and bright lume makes it instantly readable. I wear this hiking, camping, and working on cars.
Great specs. Only giving it 4 stars because the crown is a bit large for a 40mm case, but overall a fantastic rugged watch.
Perfect tactical watch. It doesn't attract unwanted attention but it's built like a tank. Very grateful for this gift.
It's their first field watch but they did it perfectly. The automatic movement is reliable and it takes a beating.
