About this entry

53% of key specs known. Missing: lug-to-lug, lug width, weight, hardening, AR coating, crown, lume.

Undone's pilot chronograph after the French Type 20 ("Iconic Pilot Watch"), tagged in the store as part of the Urban line ("urban_type20"). It is recorded apart from the 40mm Urban (VK64) because Undone states a larger case (41.5mm) with its own fluted bezel and side profile (photo filed as "TypeXX_side"), and apart from the 41.8mm Urban Sport (13.5mm, tachymeter bezel). Spec table: "Japanese TMI VK64 Mechanical-Quartz Hybrid", 316L steel, hardened domed K1 crystal, 41.5mm excluding the crown, 12mm including the crystal, 3 ATM / 30m. The photos show the VK64 layout (24-hour subdial at 3, 60-minute counter at 9) with no date window, the dial printed "Chronograph Flyback" (the VK64 resets instantly but has no true flyback), and a plain solid caseback. Whether the bezel rotates is not stated. No lug-to-lug, lug width, weight, lume or crown details are published. The listing (2023-11) is customizable through Undone's configurator, which the store data shows as USD 285, 305 and 325 price points without saying which options they cover; the USD 285 base price is recorded. It was on sale on 2026-10-30. Editions. Special Edition (USD 285; no SKU shown): "21st-century renaissance" of the Type 20 with a satin black PVD case and "big-eye" subdials whose lume glows blue, blue Arabic numerals, black Cordura strap.
