Brand History

Alpina, founded in 1883 by Gottlieb Hauser in Switzerland, began as a union of watchmakers dedicated to creating precise and durable timepieces. The brand gained recognition for its rugged sports watches, introducing the Alpina 4 in 1938, a pioneer in combining antimagnetic, shock-resistant, waterproof, and stainless steel features. Alpina became a favorite for explorers and mountaineers, embodying reliability in extreme conditions. After its revival in the early 2000s, Alpina continues to innovate with collections like the Alpinist and Startimer, blending Swiss craftsmanship with modern design, while staying true to its adventurous spirit.
