The Clifton Baumatic features the first in house movement from Baume & Mercier. The new movement has been designed with the wearer in mind, with a five day power reserve and antimagnetic to 1500 Gauss. It also has an increased accuracy only losing and gaining -4s/+6s. Due to the increased reliability of the movement, the service life has also been extended meaning the Baumatic collection needs to be serviced every 5 years, rather than every 3.
