Gmt Gold Collection “Heptagone Automatique”

European Watch Clock and Jewellery Fair 1992 BF 214
This is the selfwinding version of GMT’s “Heptagone” model. Its seven-sided water-resistant case is engraved with the names of the days of the week. Every 24 hours, a special pointer “jumps” from one case facet to the next. The proprietary, selfwinding movement and its solid-gold oscillating rotor, entirely engraved by hand, can be admired through the transparent back of the case. Each watch is individually numbered.
