The Alpina brand

Since its founding in 1883, Alpina has been renowned for its high-precision watches and innovative spirit in Swiss watchmaking. The brand pioneered the creation of robust sports watches designed for mountaineers and adventurers.

In 1938, Alpina launched the Alpina 4, a revolutionary watch combining four essential features: shock resistance, antimagnetic resistance, water resistance, and stainless steel construction. This innovation solidified Alpina's reputation as a manufacturer of reliable watches for extreme conditions.

Alpina continues to distinguish itself with collections such as Seastrong for divers, Startimer for pilots, Heritage for vintage lovers and Alpiner for outdoor enthusiasts, combining tradition and modern technology to offer watches that are both elegant and high-performing.
