The concept of 4

Independent quickset hour hand

More than any other watchmaker, Alpina was responsible for the concept of the modern Swiss sports watch, as it is known today. After several patents to ensure water-resistance and following the development of the famous Alpina "Block Uhr" in 1933, in 1938 Alpina presents the "Alpina 4": the first modern Swiss sports watch. The concept behind the "Alpina 4" was to combine the 4 essential features that defined a sports watch, in one single timepiece:

1. Anti-magnetic, 2. Anti-shock, 3. Water-resistant and 4. Stainless

Such had to be a sports watch, in the vision of the Alpina founder Gottlieb Hauser, to be able to tackle the entire vertical Alpine sports environment, from mountain climbing to alpine lake diving. In 2014, Alpina revived the Alpina "4" concept with its new "Alpiner 4" collection, dedicated to the Alpine sports universe.
