Wren looks beyond the dive watch with its sculptural Vessel Sunray

Wren has built a following through dive watches, but the Vessel Sunray heads in an entirely different direction. Developed over two years with designer Max Resnick, it is a deliberately futuristic integrated-bracelet watch whose broad, sculpted crystal gives the dial a subtle architectural frame. The goal is not to reinterpret a 1970s sports watch, but to explore what the category might look like several decades from now.

The real technical talking point is the sapphire crystal. Wren has matched curved facets on its outer face with inverse facets cut into its underside, a complex construction designed to keep the dial legible even when viewed at an angle. The brand says the first production attempts yielded only five acceptable crystals out of 100, illustrating just how much of the watch's development centred on this unusual transparent component.

Beneath that crystal sits a steel sunray dial whose finish catches the light in fine radial lines. An aqua-blue seconds hand introduces the only strong colour accent, a small visual link to Wren's earlier Diver One Aqua. The 904L stainless-steel case measures 39 by 39mm and only 10.6mm thick, with alternating brushed and polished surfaces that extend seamlessly into the integrated bracelet.

The bracelet was engineered specifically for the Vessel instead of using off-the-shelf hardware. Its tool-free quick-release design allows a switch to an optional black rubber strap, while fit can be fine-tuned through microadjustment built into the bracelet links rather than the clasp. That approach speaks to the same attention to everyday wear that informs the relatively restrained case dimensions.

Inside is a Swiss Sellita SW300-1 automatic movement beating at 4Hz, with 25 jewels and a 56-hour power reserve. The exhibition caseback shows an aqua-coloured rotor, reinforcing the dial-side colour detail. Water resistance is rated to 70 metres, appropriate for daily wear but not the professional diving environment of Wren's earlier designs.

The Vessel Sunray is limited to 150 pieces, priced at US$2,900 and available for preorder with delivery planned for the first quarter of 2027. Its most compelling idea is also its boldest: the watch has been shaped around the optical and physical possibilities of a sapphire crystal, rather than making the crystal an afterthought.
