Croft 39
GMT.

Thirty-nine millimetres, a dial called Pacific Pulse, and one extra hand that makes an awfully good watch even better.

39MM.

It looks like a 39mm watch. It wears like a 39mm watch. You'd be surprised how often that isn't the case.

First impressions

This is my kind of size.

I like a proper dive watch. I just don't think it needs to be the size of a small kitchen appliance to qualify.

The Croft is 39mm, and I mean genuinely 39mm. It looks and feels exactly the size it claims to be. No oversized case trying to convince me it's compact, no awkward proportions. Just a solid, well-judged watch that immediately felt at home on my wrist.

Then there's the colour. I thought the photographs on the listing looked good. Having the watch in hand, and subsequently pointing a camera at it from practically every conceivable angle, only made me like it more.

But the dial wasn't the main reason I wanted this one. We'll get to that extra hand shortly.

Design & case

Well built. No nonsense.

Brushed steel is doing most of the work here, and rightly so. The broad numbered bezel gives the Croft its tool-watch character, with a few polished edges to catch the light when the angle is right. Those little changes in finish are particularly satisfying through a macro lens.

At 47mm lug to lug and 13mm thick, it has enough substance to feel like a dive watch, but the footprint remains sensible. The case and bracelet look like they were designed to belong together, rather than introduced to each other at the last minute.

Spinnaker specifies a screw-down crown, sapphire crystal with anti-reflective coating, and 150m water resistance. I've not taken it down to the seabed to check. I live in Scotland, not Atlantis.

Everything about it suggests a watch meant to be worn regularly rather than treated as a delicate little ornament. That's exactly what I want.

Dial

Pacific Pulse. Turquoise to the rest of us.

Spinnaker calls it Pacific Pulse. I'd probably have called it turquoise. Admittedly, that doesn't sound quite as dramatic on a watch box.

It is a lovely colour, though. In the studio it goes deep and rich. Outside, against old leaves and driftwood, it suddenly looks brighter. There's enough blue in it to feel properly nautical, with those small orange GMT details providing just the right interruption.

The pale applied markers, broad luminous hands and framed date window are nicely balanced. There's plenty of information here, but it doesn't feel like somebody has crammed a noticeboard onto the dial.

And under magnification? The blue, the steel edging, the lume and those orange details are a treat. You know me. Give me a decent dial and a macro lens and I'll happily lose an afternoon.

The GMT & movement

The reason this watch matters.

A good-looking 39mm dive watch is already a tempting proposition. The GMT is what turns the Croft into something I'd choose over plenty of others.

Having a second time zone available at a glance is genuinely useful to me. The extra hand and 24-hour bezel add functionality without turning the dial into a puzzle. It's the sort of complication that earns its place rather than simply making a specification sheet look impressive.

Underneath it all is the TMI NH34 automatic GMT, a familiar Japanese movement that makes far more sense in a watch like this than some exotic piece of engineering I'd be frightened to knock against a doorframe. Spinnaker lists 24 jewels and a 21,600 bph beat rate.

I haven't put it on a timegrapher or conducted a controlled accuracy test, so I'm not about to invent one. What I can say is that the movement choice inspires confidence. Rock solid is the phrase that comes to mind.

Bracelet & strap

One box. Two completely different watches.

I rather like the Croft on its steel bracelet. It has the purposeful finish you'd expect, and with the blue dial it's easily smart enough for everyday wear. This is how I've been wearing and photographing it.

But there's a second personality waiting in the box: an orange rubber strap. And that's not a small detail. The colour picks up the GMT accents and promises a completely different, more playful look without the need to spend another penny.

A good watch should be able to change its mood. Steel for everyday, orange for something a little louder. Spinnaker has sensibly included both options from the outset.

The manufacturer describes it as rubber; I haven't verified the precise compound or photographed it fitted yet, so I'm not going to pretend otherwise. The option alone is a welcome touch.

On the wrist

A mainstay, not a visitor.

The big test was never whether the Croft could look good against a piece of driftwood. I can make just about any watch look interesting with enough patience and the right bit of rotten wood.

It was whether I'd actually want to wear it afterwards. The answer has been a very definite yes.

It sits naturally, doesn't demand wrist space it hasn't earned, and feels reassuringly substantial without being cumbersome. Crucially, it really does wear like a 39mm. That matters to me.

I own watches that are more expensive, more unusual and arguably more impressive on paper. But this is exactly the kind that quietly becomes a favourite, simply because I keep putting it on.

Value

£180. I think I did rather well.

I bought mine for £180. I won't pretend that didn't make the decision considerably easier.

But the thing about finding a bargain is that it only stays a bargain if you actually want to keep what you've bought. A watch that looks good in the listing and spends the rest of its life in a drawer is just an expensive way of filling a drawer.

Here I get the size I want, a dial I genuinely enjoy, a dependable automatic GMT, sapphire crystal, meaningful water resistance and a second strap for a completely different look. That's a lot of reasons to keep reaching for it.

Not everyone will find one at my price, of course. Even allowing for that, it feels like a coherent, well-specified package. And the GMT is the feature that earns the Croft its place.

Verdict

This one's staying.

Some watches are a brief fascination. They arrive, get photographed, enjoy their fifteen minutes of glory and quietly move on.

I don't think the Croft is going anywhere.

It's an excellent dive watch in what I consider the ideal size. It wears exactly as it should, the turquoise-blue Pacific Pulse dial is lovely, and the NH34 is a sensible, reliable choice. The spare orange strap is a bonus, but the GMT is what takes the whole thing from very good to brilliant.

It looks and feels like a watch that will last, and more importantly, like one I'll still want to wear. A proper long-term mainstay of the collection.

And no, before anyone asks, it isn't for sale. Nae luck, pal.

Review disclosure: I bought this watch myself. It was not gifted or supplied by Spinnaker, and the brand had no input into this independent review. Opinions are based on my own experience; technical specifications are attributed to the manufacturer.

One More Thing

Someone volunteered for the depth test.

I mentioned the 150 metres of water resistance and apparently that was all it took.

Five minutes later a very small diver appeared, fully kitted out, orange flippers at the ready, insisting he'd like to carry out his own inspection.

I pointed out that I wasn't actually planning to test the watch at 150 metres. He seemed disappointed.

He's been put in charge of the diving department anyway. Nobody else applied.
