In 2026, the Polerouter Hardstone UGPO006 was launched within Universal Genève's Polerouter Signature series, marking a contemporary reimagining of the iconic Polerouter, first introduced by Gérald Genta in 1954 for Scandinavian Airlines' early polar expeditions. This model showcases a 39mm case made of 18k rose gold, featuring the signature twisted lugs that are synonymous with the Polerouter collection. The dial is made from tiger's eye, a natural material known for its unique fibrous composition that creates a captivating chatoyant visual effect. It integrates the classic crosshair design associated with the Polerouter and is bordered by a sunray-finished inner bezel, enhancing the dial's intricate texture and depth. The watch is driven by the Universal Geneve caliber UG-110, a self-winding mechanism that utilizes a micro-rotor for its automatic winding. The Hardstone variations bring back the artistic stone dials into the Polerouter narrative, merging the traditional design elements of this classic model with luxurious materials known for their decorative qualities.
