This slender movement requires absolutely flawless construction and all the skill of the master watchmaker who assembles and polishes it with painstaking care. Cased in gold, platinum or steel – individually numbered and signed – only a few hundred ultra-slim watches leave Blancpain’s workshops every year, to be handed down as precious heirlooms from one generation to another.
