About this entry

73% of key specs known. Missing: lug-to-lug, weight, hardening, crown.

The Carbono Watch, sold under Undone's licence as Atlassian Williams Racing's watch maker (published July 2025), is a chronograph on the Time Module (Seiko) VK64 meca-quartz: centre chronograph seconds, a 60-minute counter at 9, a 24-hour register at 3 and a date at 6. Its case, tachymeter bezel, pushers and crown match the 41.8mm Tachikoma's in the photos, but the Tachikoma is a VK63 at 12.7mm, and the 41.8mm Urban Sport (VK64) has a K1 crystal and 30m, so it is recorded as its own model. Spec table: "Japanese TMI VK64 Mechanical-Quartz Hybrid Flyback Chronograph" (the VK64 resets instantly but has no true flyback), 316L steel, sapphire crystal with AR and AF coating (side not stated), 41.8mm excluding the crown, 13.3mm including the crystal, FKM rubber strap, 10 ATM / 100m; the text repeats these figures. The photos show a black-coated case, luminous hands and indices, and a see-through caseback printed with a helmet design and "AW28", marked "pressure tested to 100 meters"; the 22mm lug width is read from the strap photo ("UNDONE 22mm" printed on the strap), not a stated spec. The listing is customizable: buyers choose one of the drivers' helmet designs for the caseback and add their initials and a lucky number, at the one USD 380 price point the store data shows; it is made to order, with no returns or discount codes, and comes in a themed box. No lug-to-lug, weight or crown details are published. On sale on 2026-10-30. Its Atlassian Williams Racing sister, the Miyota 9122 FW47, is a variant of the Urban Automatic. Editions. Carbono (USD 380): celebrates the team's drivers Carlos Sainz and Alex Albon; a carbon-textured dial split into metallic and transparent blue halves "symbolizing two drivers united as one team", subdials after their helmet designs, their race numbers 55 and 23 at the matching minute marks, black-coated case with blue pushers, blue FKM rubber strap.
