You won't find many watchmakers as committed to sustainability as Baume – where possible, the Swiss house uses natural or recycled materials, like the plastic cups that have been given a new life as the casing of this limited edition 'Ocean' watch. It has a distinctive anthracite dial that features a multitude of layers and textures achieved through sandblasting and snailing, while the crown is relocated to 12 o'clock – a historical feature from the parent brand. This model is fitted with a SEAQUAL® canvas strap derived from upcycled marine plastic.
