The watch
About this watch
The Ocean Crawler Field Crawler - Black is a 40mm field watch with a black dial, powered by a Swiss automatic Sellita SW200-1 movement. It brings 400m water resistance and a sapphire crystal. It belongs to Hour VI, Field & Adventure, in our Expedition season: a natural choice for adventure travel and everyday rough use.
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.

Wore this bass fishing on Lake Worth and camping with my dogs. The legibility is instant day or night, and the 400m rating means zero stress around water. The included leather strap was pretty stiff for the first 3-4 days before breaking in, so I started on the Kevlar strap.

Hi Jesse, starting on the Kevlar strap for lake days is the way to go! That thick leather strap softens up nicely after a few wears.

400m water resistance in a field watch
Most field watches barely handle a rainstorm, so getting 400m water resistance and a screw-down crown in a 40mm case is awesome for my wrist. Wore it on the Kevlar strap while kayaking the marshes and it was rock solid.

60th Birthday Gift for My Brother
Got this for my older brother's 60th birthday since he camps and kayaks up in Wisconsin all summer. He loves the 40mm size and crisp white numerals. Only minor thing is the crown threads are tight at first and take a firm push to catch.

Hi Albert, happy 60th to your brother! Glad the Field Crawler is joining him on the water in Wisconsin, and those crown threads will smooth out nicely with use.

Son's Air Force Graduation
Bought the Field Crawler Black for my son when he commissioned last month. As a pilot myself, I wanted him to have a Swiss Sellita automatic with a clean, legible black dial and serious water resistance. He wears it every day.

Overbuilt Field Watch
Took this camping and trout fishing in Pisgah National Forest. Having 400m of water resistance and a screw-down crown in a 40mm field watch means I never have to take it off in the river. Even at 40mm, the watch has some real heft to it that took a couple days to get used to.
Gabriel H.·Charlotte, NC, US·
CSReply from ChronoSeasons
Hi Gabriel, Pisgah National Forest is a great place to put that 400m rating to work! Packing 40 ATM of water resistance into a 40mm steel case definitely gives it a solid feel.

Field Crawler 40mm Under the Cuff
With a 12.6mm case height and 40mm diameter, the Field Crawler Black disappears under a button-down cuff during client meetings. Swap it onto the leather strap and it works with a suit just as easily as jeans.

40mm Field Crawler Black SW200-1
At 40mm wide and 12.6mm thin, this is the most comfortable automatic I own for daily wear in the machine shop and out on weekends. Matte black dial is super clean under the AR sapphire crystal.

Best Man Gift
Picked up the Field Crawler Black for my brother who was best man at my wedding. He wanted a tough 40mm everyday automatic and loved the two included straps. He noted the lume is decent for a few hours, though not an all-night torch.

Hi Raymond, congrats on your wedding! Glad your brother is enjoying the Field Crawler, and we appreciate the note on the lume.
