Otherwise, the specs of the time-and-date model are similar to the previous generation of the Octo Roma: 41mm case diameter, a bracelet with link a nice combination of polished and brushed link surfaces (now with a system that allows you to easily change straps, so you link can easily swap to the rubber strap that's also included), and the same Bulgari caliber BVL 191. Water resistance is up to 100 meters in both models, an improvement over the previous 50 meters (both models have a screw-down crown).

What It Is: The Polerouter is a handsome Gerald Genta-designed vintage piece that's managed to stay relatively affordable for a long time. It was the young Genta's first major design, having link debuted in 1954. In conjunction with SAS (that's Scandinavian Airlines System), Universal Geneve developed the watch to honor the link new "polar route" that would shrink the distance between Los Angeles link and Copenhagen considerably by flying directly over the magnetic North Pole.
