Conclusion / Condition:
Great vintage piece with a relevant back story about micro rotor movement between Universal Geneve:
Buren patented the first micro-rotor automatic watch movement (the Intra-matic) in 1954. They subsequently licensed the technology to companies such as Bulova and Hamilton. Universal Geneve applied for their patent in May of 1955. The microrotor movement in the Polerouter series was nearly identical in design specification to the Buren Intramatic. Buren won a patent infringement case, and U.G. had to pay Buren royalties for each microrotor it used until their patent was granted. During that early period, UG was apparently required to label their movements as "patent pending", and, as a result of the dispute, were not able to record the actual patent until May 15, 1958.
