The L'evolution Semainier incorporates all of the features that hallmarked the Collection when it was unveiled last year, including a complex multi-layered dial, bold numerals, crisp double stepped bezel, removable lugs and a ~44mm case diameter. This particular version of the L'evolution Semainier features a stainless steel case and a multi-layered gray dial and straps on using a black alligator leather strap. It also shares Blancpain’s new côtes paraboliques decoration which sets off the extra large jewels of the Blancpain caliber 37R8G automatic movement, all of which is visible through the watch's clear case back.
