Description
Alpina, founded in 1883, has been a pioneering force in Swiss watchmaking. The Alpiner 4 collection, first introduced in 1938, revolutionized sports watches by establishing four essential criteria that remain crucial to this day. The AL-525BR5AQ6-SR model continues this legacy while incorporating modern innovations.
Design Elements
Case Architecture
