Movement and Service
This Universal Genève Polerouter, an early model fitted with the original Caliber 138 SS bumper automatic movement introduced in 1948, offers a glimpse into vintage Swiss watchmaking. Unlike the later 215-27 micro-rotor versions, this bumper-style movement—though less efficient than full rotor automatics—was found to be in very good mechanical condition. Featuring anti-shock balance jewels and an indirect-drive sweep seconds hand, it demonstrated the durability of quality mid-century engineering. During servicing, the movement underwent complete disassembly, careful inspection, and thorough cleaning as part of a full vintage watch repair process. Once reassembled and properly lubricated, it performed reliably and kept accurate time, preserving both the function and heritage of this classic Universal Genève timepiece.

The Universal Genève Polerouter was designed (by known designer Gerald Genta) to commemorate Scandanavian Airlines Systems polar flights from North America (LA, New York) directly to Europe. The name ”Polerouter” originated from the original name idea of Polarouter (flight route over the north pole). The original antimagnetic pieces were issued to the SAS’s pilots who flow this particularly challenging route. This model then went on to become a successful family of timepieces for Universal Genève. For more information on the history visit A Brief History of the Universal Geneve Polerouter
