A rare 1965 Universal Genève Polerouter Date in exceptional unpolished condition. The twisted lug case retains sharp, original lines with honest light wear, and the silver sunburst tritium dial is pristine. The steel dauphine hands and tritium markers have developed a rich pumpkin-orange patina — exactly what collectors look for in a well-aged example. Freshly serviced.
History
The Polerouter story is really two stories: one about who invented the technology, and one about who made it famous.
Buren Watch Company won that first race. Their chief engineer Hans Kocher filed the patent for a "planetary rotor" — the first micro-rotor — on June 21, 1954. By integrating the oscillating weight into the same plane as the wheel train rather than sitting on top of the movement, Buren built the thinnest automatic watches in the world. They successfully sued Universal Genève for patent infringement and went on to license the technology to Hamilton, Bulova, and IWC, eventually forming the foundation for the iconic Chronomatic Calibre 11.
Universal Genève independently developed their own micro-rotor and filed for a patent 11 months after Buren, in May 1955. They lost the infringement case and paid Buren a royalty of 4 Swiss francs per watch — early Polerouters (Caliber 215) were even engraved "Patented Rights Pending" to navigate the legal situation. But none of that diminished what Universal Genève actually made.
In 1954, Universal Genève tapped a 23-year-old Gérald Genta — years before his work on the Royal Oak and Nautilus — to design a watch for SAS (Scandinavian Airlines System) to commemorate their pioneering polar flights from Los Angeles to Copenhagen. Flying over the North Pole posed a real problem for timekeeping: the extreme magnetic fields wreaked havoc on mechanical movements. Universal Genève, already known for anti-magnetic work, was SAS's official watch supplier. The first Polarouters were presented to the flight crew upon landing at LAX, with the SAS logo on the dial. Only a few hundred were ever made.
The watch was officially released in 1954 as the Polarouter, renamed Polerouter a year later. In the late 1950s, a steel Polerouter was priced the same as a Rolex Explorer. The line ran until 1969.
Buren invented the micro-rotor. Universal Genève made it iconic.
