====== Baume & Mercier Clifton Baumatic 5-Day Chronometer ====== The **Clifton Baumatic 5-Day Chronometer** is an [[automatic]] watch from [[Baume & Mercier]] introduced in [[2018]] ===== Overview ===== Introduced at [[SIHH]] in [[2018]], the Clifton "Baumatic" was notable in that it uses a new "[[in-house]]" automatic movement, the first for the brand, with a [[silicon]] [[hairspring]] and [[escapement]], a first for a [[Richemont Group]] company. This new [[BM12|Cal. BM12-1975A COSC]] was developed by [[ValFleurier]], the in-house movement specialist at [[Richemont]]. The basic architecture is similar to the [[ETA 2824]] but it is substantially different in most respects. Additionally, this movement delivers 120 hours of power, exceptional for a [[single barrel]] movement. As noted in the name, this movement is certified as a [[chronometer]] by the [[COSC]]. The watch itself is impressive in design, with a 40 mm stainless steel case, [[cross-hair]] white dial, and faceted lance-shaped hour and minute hands. {{tag>Watch_models Baume_&_Mercier_models}}
