Temporal Works
Temporal Works is a watch brand co-founded by Mark Cho and Elliot Hammer, the pair behind the watch collaborations of The Armoury, the menswear retailer Cho founded with Alan See in 2010, which operates in New York and Hong Kong. Cho's earlier watch collaborations include H. Moser & Cie., Unimatic and Paulin. Temporal Works launched its first watch, the Series A, on 4 December 2025, selling only through The Armoury's website and shops; Cho has described the aim as making the "navy blazer" of watches, something easy, versatile and wearable. The brand's own pages describe its design as international and say each watch starts from a blank slate, with an emphasis on form, finish, colour and comfort. They do not say where the company is based, so the New York and Hong Kong link comes only from its retailer.
The Series A is made in Japan by a single production partner that Temporal Works does not name. It is a slim manual-wind watch with a 37 mm monobloc case in 316L steel, 10 mm thick, 45.88 mm lug to lug with 19 mm lugs, inspired by the space-age forms of the 1960s and 1970s and finished with textured surfaces (Zaratsu polishing on the Sector). It has a closed screw-down caseback, dual anti-reflective sapphire crystal and 50 m water resistance. The movement is the Swiss Sellita SW210-1 b D4, hand-wound, 18 jewels, 28,800 vph, with about 42 hours of power reserve and a stated accuracy of plus or minus 20 seconds a day. The hands are faceted like fountain-pen nibs, with two polished sloping sides and a matte top. Straps are by Jean Rousseau, and a custom 19 mm tapered steel-mesh bracelet designed by Staib is sold separately for $250. Each watch is $2,500.
The range grew quickly. The first Series A models are the Sector, a two-tone dial with oversized brushed quadrants and a toothed minute track in black or navy, and the Fortune, an unadorned glossy red lacquer dial. The Rambler, released in 2026, puts the same case in a bead-blasted finish with a six-segmented lumed dial, pilot-style hands and an orange seconds hand, in Black Sesame and Red Bean colourways on olive canvas or grey Alcantara straps. The Romanesque, the model pictured, was designed with London designer Lee Yuen-Rapati from a 2022 drawing in his One Hour Watch series, which reduces Roman numerals to simple vertical and horizontal strokes. It has a two-layer "sandwich" dial in which a silver-white opaline top layer is laser-cut to reveal a glossy midnight-blue layer beneath, two hands, and a light grey pebble-grain calfskin strap; it is limited to 50 pieces at $2,500 and was listed for pre-order with shipping in November. The Armoury's listings for several earlier Series A variants showed them as unavailable when checked, and the brand states no edition sizes for the other models.
