Universal Geneve - Bumper-Automatic Calatrava
We are proud to offer Rare pre-50s Calatrava: Universal Bumper-Automatic.
WHY WE LOVE IT? An early UG automatic -- we date it to 1949 -- and a predecessor of the celebrated PoleRouter.
Made in 1949 and so in a time when Rolex had secured the patent protection for 360°-rotor automatics -- and the bumper automatic was a way to offer a self-winding movement without breaching these regulations.
