The Blancpain company
In 1735, Jehan-Jacque Blancpain founded the Blancpain company of the same name in the village of Villeret. The company is engaged in the production of watches, with particular emphasis on the flatness of these. Blancpain is a family-run business until 1932. In that year the representative of the 7th generation died and the company was handed over to his assistant. In the following years, there are repeated mergers with other watch manufacturers.
The Fifty Fathoms collection
Since 1953, the company has been particularly concerned about the marine world. The Fithy Fathoms collection reflects this affinity and thus helps divers, scientists and underwater photographers on their journeys of discovery. The models in the collection are always trying to push the boundaries and create new innovations.
