Baume & Mercier has been developing its expertise for 190 years. This expertise is based on the principle of “établissage”, meaning every stage in the creation of a timepiece is controlled in-house, as is the assembly of its various components. This choice reflects the Maison’s strong principles and is a guarentee of the highest quality. This tradition of excellence at Baume & Mercier is based on the design and development of its products at the Maison's headquarters in Geneva, and on the "établissage" process carried out at its workshops in the Swiss Jura, in Les Brenets. This means that watch production is centralized in Switzerland. Baume & Mercier attracts the best talents to ensure it achieves the ultimate quality and respect.
