Wren’s latest Diver One has the kind of community pull that microbrand collectors tend to notice quickly.
The Diver One Obsidian marks the brand’s second collaboration with Ben Cook of Ben’s Watches, bringing a darker visual treatment to Wren’s core dive watch platform.
It’s a limited release with a Swiss automatic movement, a black DLC-coated case and bracelet, and the first 100 pieces individually numbered.
At a glance
- Wren has released the Diver One Obsidian as its second limited-edition collaboration with Ben Cook of Ben’s Watches.
- The watch uses a 41mm black DLC-coated stainless steel case, Sellita SW200 automatic movement, ceramic bezel and 200 metres of water resistance.
- Pricing is set at $1,195, with shipping expected around December 18 and the first 100 pieces numbered.
A darker take on Wren’s core diver
The Obsidian name does exactly what it suggests, giving the Diver One a blacked-out character without turning it into a caricature of a tactical watch.
The case and flat-link bracelet are both black DLC-coated stainless steel, while the ceramic unidirectional bezel keeps the look cohesive and functional.
At 41mm across, 47mm lug to lug and 13.3mm thick including the box crystal, the Diver One Obsidian sits in the familiar modern dive-watch zone.
Those proportions should make it substantial enough to feel purposeful while staying within the range many collectors still consider wearable.
The Ben’s Watches connection
This is the second time Wren has partnered with Ben Cook, the founder of Ben’s Watches, on the Diver One platform.
That repeat collaboration matters in the microbrand space, where limited editions can often feel fleeting.
Wren founder Craig Karger is also well known through Wrist Enthusiast, which gives the project a distinctly enthusiast-led feel rather than the air of a detached licensing exercise.
The result is a watch aimed squarely at collectors who follow smaller independent brands closely and enjoy releases shaped by online watch communities.
Swiss movement and dive-ready hardware
Inside the Diver One Obsidian is the Sellita SW200, a Swiss automatic movement with roughly 38 hours of power reserve.
It’s a sensible choice for this segment, familiar to collectors and widely used across independent and established watch brands.
The watch is rated to 200 metres of water resistance and uses a sapphire box crystal, pairing vintage-leaning geometry with contemporary durability.
Swiss Super-LumiNova BGW9 appears on the hour markers, hands and bezel markers, with a blue-green glow that should suit the monochrome case treatment well.
A hydraulic press caseback engraving of a wren adds a brand-specific detail on a watch that otherwise leans heavily into clean, functional diver cues.

Who this release is for
The Diver One Obsidian will likely appeal to collectors who want a Swiss-made diver from a smaller brand with a clear point of view.
It’s also a natural fit for anyone who follows Ben’s Watches and prefers collaborations that feel connected to a real watch community.
At $1,195, it sits in a competitive part of the microbrand market, where buyers tend to care closely about movement choice, finishing, proportions and personality.
Buyers outside the United States should also account for any applicable duty or VAT.
For Wren, the Diver One Obsidian strengthens a developing identity around enthusiast-driven watches with enough specification to be taken seriously.
For collectors, it’s a sharp black diver with a credible movement, practical water resistance and a collaboration story that feels more grounded than most.
