Founded in 1883 by Gottlieb Hauser, Alpina got its start as the Alpina Union Horlogère, a collaboration of Swiss watchmakers known as Alpinists. Together, the Alpinists pooled resources to develop both movements and finished watches. Alpina became the official brand name in 1908 for its 25th anniversary. Today, Alpina is best known for luxury sports watches, with a broad collection including pilot, outdoor, and dive watches. Over 80 years ago, the Alpina 4 established four key standards - antimagnetic, antishock, water-resistance, and stainless steel – that are still followed today in the Alpiner collection. Frédérique Constant acquired Alpina in 2002, helping the brand continue in-house movement development including its first tourbillon in 2009. Both brands are now subsidiaries of Citizen Holdings.
