Undone's 40mm "Enamel" automatic with an enamel-inspired sunray dial "forged at 800°C, cooled naturally, and polished by hand", first released in 2025 as the Azura and Verde (listed 2025-08, published 2025-12), each "engraved /250". The SKUs (URB-RTO) and the "Urban Automatic" print on the rotor place it with Undone's Urban watches, and the retailer Ocarat sells it as the "Urban Enamel"; it is unrelated to the Miyota-powered Urban Automatic. This model is the K1-crystal version: the Azura and Verde spec tables give "Lens - K1 Crystal" and both feature blocks say the dial "sits beneath a domed K1 crystal", while the 2026 Ambra, Indaco and Mora listings give a "double-curved sapphire crystal" in their text and tables, so those are recorded as Enamel (sapphire crystal). Ocarat's listing of the Azura states a domed sapphire crystal; Undone's own pages are followed. Spec table, the same on both listings: "Japanese Timemodule NH35 Automatic", 316L steel, K1 crystal, 40mm excluding the crown, 13.8mm including the crystal, 10 ATM / 100m. The Azura's feature block names an "NH36 automatic movement", but its spec table and caseback photo say NH35 and its dial shows only a date (at 6), so the NH35 is recorded. The Azura's table lists a "Rubber Strap", while its text and photos show a vintage blue leather strap, which is recorded. Both feature blocks mention luminous markers. The photos show a polished and brushed case and a see-through caseback. Each listing offers the watch on its leather strap (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, lug width, weight or crown details are published. Editions. Azura (URB-RTO-BLU, bracelet URB-RTO-BLB, USD 410 / 460, 250 pieces): navy dial "made for depth and stillness" with red accents, vintage blue leather strap. Verde (URB-RTO-GRN, bracelet URB-RTO-GRB, USD 410 / 460, 250 pieces): green dial with yellow accents, vintage green leather strap.
