Undone's 40mm "Enamel" automatic (SKU prefix URB-RTO, "Urban Automatic" print on the rotor) in its 2026 version with a sapphire crystal: the Ambra, Indaco and Mora (listed 2026-07, published 2026-08-20). Their descriptions give "a 40mm polished and brushed stainless steel case", the "Japanese NH35 automatic movement", "double-curved sapphire crystal" and "100m water resistance", and say the dial "is fired at around 800°C, cooled naturally and polished by hand" over a radial sunray texture. Spec table, the same on all three: "Japanese Timemodule NH35 Automatic", 316L steel, sapphire crystal, 40mm excluding the crown, 13.8mm including the crystal, 10 ATM / 100m. The 2025 Azura and Verde, whose listings state a domed K1 crystal, are recorded as Enamel (K1 crystal). The photos show a date at 6 and a see-through caseback. The 20mm lug width is from the Indaco strap photo's file name ("20mm_Leather"). Each listing offers the watch on leather (USD 410) or on a steel bracelet (USD 460, own SKU); the bracelet photos show three links per row; no clasp details are given. No lug-to-lug, weight, lume or crown details are published. The listings carry a "Limited Quantity" badge but no edition size, so the model is recorded as in production. Editions. Ambra (URB-RTO-PLO, bracelet URB-RTO-POB, USD 410 / 460): "golden amber deepens into copper and burnt orange", vintage brown leather strap. Indaco (URB-RTO-VLT, bracelet URB-RTO-VLB, USD 410 / 460): electric indigo to violet with turquoise accents, black leather strap. Mora (URB-RTO-PRL, bracelet URB-RTO-PRB, USD 410 / 460): deep plum moving to berry and pink, black leather strap.
