Baume & Mercier Baume

A short-lived eco experiment rather than a classic B&M line. 'Baume' launched in 2018 as a separate, online-only sister brand with a sustainability mission: cases and straps made from upcycled and natural materials (cork, recycled plastics, natural fibers), no precious metals or animal products, and affordable third-party movements. The look was clean and minimalist, unisex, around 41mm. It has since been wound down, so it's a niche, of-its-moment piece now rather than a current collection. One for someone drawn to the eco story.
