European Watch Clock and Jewellery Fair 1987 BF 112
The double-face wristwatch: this novel approach is based on a patented system featuring a centre axis and spring-mounted stops. The watch’s appearance can thus be totally changed in a flash. Pictured : 18K yellow gold case with mother-of-pearl dial framed by a diamond-set bezel. The other face has a pair of dials providing the time of day in two timezones. Quartz movements. Other models are available : white and yellow gold cases, mechanical and quartz movements, moon phases, with or without diamonds... (GMT Gold Collection)
