UNIVERSAL GENEVE Unisonic Ref. 152102/01 18K – 1970s

A rare and beautifully preserved Universal Genève Unisonic Ref. 152102/01, crafted entirely in 18K solid gold, representing the brand’s bold step into the electronic age of the early 1970s. This example remains unpolished, with sharp lines and well-defined hallmarks, preserving the watch’s authentic geometry and factory finish. The gold case has developed a rich, naturally aged surface, displaying subtle oxidation and warmth that only decades of untouched patina can create. Powered by the tuning fork movement, the Unisonic delivers the smooth, humming precision characteristic of early electronic horology – a fascinating blend of mechanical craftsmanship and emerging technology. The clean, minimalist dial with its date aperture at three o’clock maintains perfect balance and understated elegance, underscoring Universal Genève’s mastery of refined design. Seldom seen in this configuration and condition, this Unisonic stands as a remarkable relic of Universal Genève’s innovative 1970s period – a piece where heritage, rarity, and honest aging meet in perfect harmony.
