The self-winding Baumatic movement ensures optimal reliability. In addition to 120 hours (5 days) of autonomy, Clifton Baumatic watches offer great chronometric precision (–4/+6 seconds per day for the COSC-certified models). They resist to the main magnetic fields of daily life. These models only require maintenance service once every seven years rather than three to five years recommended for a traditional watch. Any high watchmaking aficionado will appreciate these remarkable achievements.
