We are proud to offer this rare super early "broad arrow" Polerouter for sale. These broad arrow Polerouters seldom come up for sale publicly; it may be years before a collector has the chance to acquire one in original condition. This particular model features the original radium in the hands and retains the original radium circle on the inside, with open spaces for the hour markers.
This Polerouter carries reference number 20217 and is powered by the Universal Genève bumper movement 138S. In later models, the now-infamous microrotor movements were introduced. Because this model has the bumper movement, the case design had to accommodate the thicker movement, resulting in a thicker case. Although this case measures the same 35.5mm as later Universal Genève Polerouters, this watch wears significantly larger due to its thicker case.
We will leave you with a small read from the 'The Broad Arrow Polerouters' guide writen by 'Hamblar'.
"All of these references are described within the advertisement as having a “Nitelite Marker Ring”, in reference to the radium-containing luminous material that was applied generouslyaround the marker ring. Additionally, they had matching radium luminous material on the hour and minute hands. Often this radium material was removed or replaced during servicing or repair over the 60+ years since their manufacture. As these BA references had lume on the hands and the marker ring, there was no need to have lume pips where we often seem them on the hour markers of Polerouter dials. As such, all BA dials were constructed with “non-lume” dials."
