Ocean Adventure

Monro Adventure followed its original travel-focused Adventure collection with the Ocean Adventure in 2024. The project was successfully crowdfunded on Kickstarter, where 160 backers pledged more than £54,000 against a £10,000 target.

The Ocean range is deliberately more tool-watch focused: 41mm cases, automatic movements, sapphire crystals and 200m water resistance, offered in both stainless steel and CuSn8 bronze. The steel models are individually numbered editions of 200 pieces, including this Atlantic Blue MOA-1.

That limited-production approach suits Monro. It feels less like an attempt to manufacture another generic diver and more like a distinct branch of the same design language seen elsewhere in the range.

At 41mm across, 48mm lug-to-lug and 15mm thick, the Ocean Adventure is not pretending to be a wafer-thin dress watch that accidentally wandered into the sea. It has the proportions of a modern mechanical diver and wears accordingly.

The important part is how those dimensions are handled. The brushed 316L steel case is broken up by a polished facet that runs from the lug towards the crown guard, giving the case some architecture rather than leaving it as one large block of steel. From the side, that contrast becomes one of the most interesting details on the watch.

The screw-down crown is substantial and easy to grip, while the 20mm lug width keeps the strap proportions sensible. It is a fairly chunky watch, yes, but deliberately so.

Under softer light the dial can look almost black. Give it a stronger source and the galvanic gradient begins to reveal a deep navy centre, with enough movement across the surface to stop it feeling flat.

That subtle dial is surrounded by a much more graphic arrangement. Large applied markers, bold faceted hands and the white minute track make the watch extremely legible, while the black ceramic bezel carries raised-looking silver numerals and a broad luminous triangle at twelve.

The handset is one of the details that gives the Ocean its own identity. It is angular without becoming fussy, and the circular elements in the hands line up in a pleasing little piece of visual engineering when the planets, hands and your patience all cooperate.

Above the dial is a double-domed sapphire crystal with anti-reflective coating. It brings a little vintage distortion at the edges without turning the watch into a nostalgia exercise, and it can produce some attractive reflections when the light is allowed to misbehave.

Inside is the Seiko NH38A, a 24-jewel automatic movement with around 41 hours of power reserve. The choice makes sense here. It is a straightforward, widely understood movement, and because the NH38A is a no-date calibre there is no phantom date position hiding in the crown operation.

It is not exotic. It does not need to be. In a £350 dive watch, reliability, serviceability and getting on with the job count for rather a lot.

Then the lights go out and the Ocean Adventure stops behaving sensibly.

Monro uses two grades of Swiss Super-LumiNova across the dial, hands and bezel. Green lume picks out the hour markers and parts of the handset, while blue illumination lights the minute scale, bezel pip and complementary hand elements.

The result is not merely bright; it is visually structured. The two colours separate timing information in the dark and, from a purely photographic perspective, turn the watch into its own small neon installation. I may have taken more lume photographs than were strictly necessary. Occupational hazard.

The steel version comes on a quick-release three-link bracelet with an on-the-fly micro-adjustment clasp, and Monro also includes its navy NBR rubber military-style strap.

The bracelet gives the Ocean the more conventional steel-diver character and suits the weight of the case. The rubber changes things immediately: lighter, more casual and much more obviously tied to that Atlantic Blue identity.

More importantly, neither feels like the obligatory spare that stays in the box forever. Both make sense on the watch, and the quick-release hardware means changing between them does not require a spring-bar tool, a prayer and fifteen minutes crawling around the floor looking for something very small.

This is not one of those watches where the specification sheet says 41mm and the wrist somehow insists it is 38. The Ocean Adventure has genuine visual presence, helped by the broad bezel, large markers and substantial case.

But the 48mm lug-to-lug keeps that presence controlled. On the bracelet it feels reassuringly solid rather than oversized, and the short transition from case to bracelet helps the watch sit naturally.

If your preference is exclusively for compact 38–39mm watches, the Ocean will feel like a step up. For a 200m diver, though, the proportions are entirely at home.

At its current £350 retail price, the Ocean Adventure enters one of the busiest parts of the microbrand market. There is no shortage of NH-powered divers with sapphire crystals and ceramic bezels.

Where the Monro earns its place is in the details around those specifications: the case finishing, the distinctive handset, the dual-colour luminous treatment, the quick-adjust bracelet, the second rubber strap and the limited production run.

The NH38A will not impress someone shopping purely by movement hierarchy, and 15mm is not especially slim. Those are reasonable caveats. But the overall package feels coherent rather than assembled from a checklist.

The Ocean Adventure gets the fundamentals right: 200m water resistance, sapphire, ceramic, a dependable automatic movement, strong legibility and a bracelet that is actually useful rather than merely present.

What makes it more interesting is that Monro has not stopped there. The polished case facet, unusual handset, crisp white timing track, deep blue dial and frankly enthusiastic lume give it enough identity to survive comparison with the dozens of other capable microbrand divers around the same price.

It is substantial, and the movement is deliberately workmanlike rather than glamorous. Neither bothered me once it was on the wrist.

Most importantly, it is recognisably a Monro. After spending time with both the Urban and the Ocean, that emerging family resemblance may be the brand's strongest trick.

Apparently.
