Vintage 1970s Tenor-Dorly Automatic Jump Hour Digital Watch Swiss 21J Date 42mm

About this watch

A bold space-age "digital" mechanical watch: instead of hands, the hours jump in a framed window while the minutes turn on a rotating disc, read against a central line across the smoked brown dial. The dial is signed TD Tenor-Dorly and "21 Jewels Automatic Incabloc", with a date window at 6 o'clock.

The large brushed gold-tone cushion case measures approx. 42mm. Inside is a Swiss automatic movement whose rotor is marked "Twenty One 21 Jewels, TD, Unadjusted, Swiss", as shown in the photos. It is fitted to a brown croco-pattern leather strap.

Brand heritage

Tenor-Dorly was a Swiss watch brand best known today for its 1970s automatic watches with jump-hour displays. In the late 1960s and 1970s, Swiss makers answered the excitement of the Space Age with mechanical "digital" watches that showed the time on rotating discs, years before LED and LCD watches arrived. Tenor-Dorly's jump hours, with their large cushion cases and smoked dials, are now popular with collectors of retro design.
