C60 Trident Lumière ‘Green Fifteen’ x Bark & Jack
Christopher Ward x Bark & Jack: A Dive Watch That Knows Exactly What It’s Trying to Be
Collaborations are everywhere at the moment, and if we’re being honest, plenty of them feel like exercises in logo placement rather than meaningful design. This one, thankfully, doesn’t.
The Christopher Ward C60 Trident Lumière ‘Green Fifteen’ x Bark & Jack comes from a long-standing relationship rather than a sudden marketing brainstorm. Adrian Barker has been reviewing Christopher Ward watches for years, long before collaborations became a currency of the YouTube age. So when this one finally landed, it felt less like a surprise and more like an inevitability.
Rather than reinventing the wheel, the project sensibly starts with the C60 Trident Lumière, easily one of Christopher Ward’s most mature designs. It’s slim, technically impressive, and refreshingly self-aware in accepting that most of its owners are desk divers rather than saturation professionals. That honesty is arguably the Lumière’s biggest strength — and it’s exactly where Barker’s input makes the most sense.
The titanium case remains largely untouched, and that’s no bad thing. At 41mm wide, just under 48mm lug-to-lug, and only 10.85mm thick, it’s one of those rare modern dive watches that doesn’t feel like it’s trying to overcompensate. The Light-catcher case, helium escape valve, polished chamfers, and bolt-on crown guards strike a good balance between refinement and genuine tool-watch credibility.
Where things start to shift is on the dial. The ‘Green Fifteen’ opts for a matte black finish with a softened granular texture that pushes the watch firmly into utilitarian territory. The raised chapter ring adds depth without fuss, and the switch from baton indices to spot markers is a small but meaningful change. It’s all about orientation and legibility here — less jewellery, more instrument.
Branding is handled with surprising restraint. The Bark & Jack logo is present, but only visible under UV light, with a torch included in the box. It’s a clever move: the collaboration is acknowledged without hijacking the dial. You can wear this watch without feeling like you’re advertising someone else’s channel, which frankly shouldn’t be a novelty, but here we are.
The bezel is the star of the show, though. Inspired by classic military dive watches, it features full-minute markings and a bi-colour lume setup: green for the first 15 minutes, (hence the name) blue for the rest. The Globolight minute hand mirrors the green tone, while the hour and seconds hands glow blue. From a functional standpoint, it makes perfect sense, the first 15 minutes are the critical window for dive timing. From an aesthetic standpoint, it looks properly brilliant in the dark. Sometimes form and function really do align.
Flip the watch over and things get unexpectedly personal. The caseback carries a multi-finish Bark & Jack logo surrounded by a textured pattern inspired by Adrian’s late grandfather’s pocket knife. It’s a small detail, but it adds a layer of sincerity that’s often missing from collaborations. This isn’t just a watch designed to sell, it’s one designed to mean something.
Inside, the COSC-certified Sellita SW300-1 keeps things sensible, offering a 56-hour power reserve and proven reliability. No drama, no gimmicks, exactly what you want in a watch that leans so heavily on real-world usability.
The watch comes on Christopher Ward’s excellent Bader bracelet with on-the-fly adjustment, alongside an exclusive Bark & Jack rubber strap. Made in France, the strap combines a fabric-style texture with a rubber lining and titanium hardware. It’s practical, comfortable, and doesn’t feel like a token inclusion.
At £2,150 / $2,995 / €2,850, this isn’t an impulse buy, and the limited order window means you’ll need to be decisive. Deliveries aren’t expected until March 2026, which will test the patience of even the most committed fans.
Here’s the thing: this doesn’t feel like a watch designed to chase hype. It feels like a watch designed by someone who has actually worn, criticised, and lived with dive watches for years — and wanted to fix a few things rather than shout about them. That’s rare.
Will everyone love it? No. The price, the wait time, and the fact it’s quietly purposeful rather than flashy will put some people off. But for those who value legibility, restraint, and honest design over empty theatrics, this might just be one of the most considered collaborations we’ve seen in a while.
It’s clear that Adrian knows exactly what he likes, and this feels about as close to his ideal watch as you’re likely to get. A distilled expression of what Formula truly stands for. There are familiar nods to other references woven throughout the design, and rightly so. Taste doesn’t exist in a vacuum, and when you know what works, there’s no shame in refining it rather than reinventing it.
This could genuinely be the Christopher Ward that ticks every box for me. I already thought the Lumière was an excellent watch, but this feels like a meaningful step beyond that, more refined, more assured, and elevated by a considerable margin.
In a sea of collabs that try to be everything at once, the ‘Green Fifteen’ succeeds by knowing exactly what it is, and, just as importantly, what it isn’t.
