Its specifications make a compelling tool-watch proposition on paper, but the limited order window has closed: the launch price is historical, and current stock or resale pricing has not been established.
What the Green Fifteen is
The Green Fifteen is a collaboration between Christopher Ward and Bark & Jack, based on the C60 Trident Lumière. It was offered for orders from February 5 through February 12, 2026, according to the Christopher Ward launch announcement. Adrian Barker described the design goal in his launch video: “From the very beginning, the goal was simple: to create our ultimate tool watch.” That is the collaboration’s stated ambition, not evidence of independently tested performance.

Specifications and movement
| Specification | Reported detail |
|---|---|
| Case diameter | 41 mm |
| Case thickness | 10.85 mm |
| Case material | Grade 2 titanium |
| Water resistance | 300 m / 30 ATM |
| Movement | Automatic Sellita SW300-1, COSC-certified |
| Power reserve | 56 hours, as listed by Hodinkee |
The dimensions and construction are reported in the T3 launch coverage and the collaboration’s launch materials; Hodinkee also lists the 56-hour reserve and 30 ATM rating in its specification coverage. These are published specifications, not results from an independent test. The 10.85 mm thickness is notably restrained for a watch rated to 300 m, although case diameter and thickness alone cannot establish how it will fit a particular wrist.
What makes the design distinctive
Green Fifteen bezel
The bezel’s minute scale is divided by lume colour: green marks the first 15 minutes, while blue marks the remaining 45. This gives the name “Green Fifteen” a functional reference, rather than making green merely a decorative accent. The minute hand is also described as green-glowing, with the other hands glowing blue. The contrast is intended to make elapsed time easier to read, but no independent legibility test is available.

UV-revealed dial detail
The Bark & Jack logo is hidden on the dial until illuminated with ultraviolet light. A UV torch is included in the launch package, making the concealed mark an interactive detail rather than an always-visible logo.
Engraved caseback
The solid caseback carries a texture inspired by a pocket knife that belonged to Adrian Barker’s late grandfather. It is a personal collaboration detail on a watch whose dial otherwise keeps the branding discreet.

Bracelet, strap and intended use
The launch package included a titanium Bader bracelet with on-the-fly adjustment, a Bark & Jack rubber strap with titanium hardware, and a UV torch. That gives the owner two wearing configurations without requiring a separate strap purchase at launch. The bracelet’s adjustment system is the more relevant feature for changing fit throughout the day; the rubber strap is the alternative for a more water-oriented or casual setup. The launch descriptions do not establish comparative comfort, flexibility, clasp feel, or how either option wears on different wrists, so those remain personal fit questions rather than proven advantages.

The historical launch price was £2,150, €2,850, or $2,995, with the order window running February 5–12, 2026. Those figures describe the original offer, not a current price. The published material reviewed here does not establish present-day brand stock, a reopened order period, resale pricing, or successor availability. Anyone seeking one now should verify the seller, condition, included bracelet and strap, and current asking price directly before treating any listing as representative of the market.

Is the Green Fifteen worth the price?
As a specification-led proposition at its launch price, the strongest case is the combination of a COSC-certified automatic movement, 300 m rating, lightweight titanium construction, restrained thickness, unusually differentiated lume layout, and two included wearing options. The design also has collaboration-specific details that go beyond a logo on the dial. The main qualification is that these attributes are reported specifications and design features, not a firsthand assessment of timing, water resistance, finishing, or comfort. With the order period closed and no verified current market price, value today depends on the actual offer and the buyer’s preference for this particular design.
