A rare and fascinating example of experimental Swiss watchmaking from the 1970s, this AGON Saltarello Digital Swiss belongs to the short yet significant era of mechanical digital jump-hour watches, developed before and during the advent of quartz movements. Before quartz technology became dominant, several Swiss manufacturers explored alternative solutions to offer a “digital” time display while remaining faithful to traditional mechanical watchmaking. This led to the creation of the so-called “saltarelli” or jump-hour watches, in which time is displayed through rotating discs driven by a mechanical movement. Produced in relatively limited numbers, these watches are today highly sought after by collectors, both for their historical significance and for their distinctive space-age design, emblematic of the period. The AGON offered here is a genuine witness to this crucial transitional phase in Swiss horology.
