Universal Geneve Unisonic, Ref. 852100, Tuning Fork
Sale price  $975.00 Regular price  $1,250.00

A quiet disruptor from the early 70s, the Unisonic represents Universal Genève’s leap into the electronic frontier. Powered by the Caliber 1-52 tuning fork movement, this piece hums rather than ticks, driving a smooth, sweeping second hand that melted the hearts of many at the time. This example features a beautifully preserved cream dial with sharp baton indices, a framed date window at 3, and the subtle UNISONIC signature that set it apart. The stainless steel case remains crisp with strong edges and is paired with its original signed UG bracelet, a rare and complete package. At a time when tradition met experimentation, the Unisonic was Universal Genève’s answer. One that is a clean, confident blend of mid-century elegance and 70s innovation. It hums! It floats! It's history in motion!
