Blancpain Fifty Fathoms 5071-1110-B52A Description

The Blancpain Fifty Fathoms Bathyscaphe Quantième Annuel, reference 5071-1110-B52A, was introduced in 2018, marking the first time Blancpain equipped its Bathyscaphe line with an annual calendar complication. This model successfully merges the robust, professional specifications of a true dive watch with the practicality and elegance of a sophisticated calendar function. The watch features a satin-brushed stainless steel case, a unidirectional ceramic bezel, and a meteor grey dial. The integration of an annual calendar, which only requires a single adjustment per year, into a watch water-resistant to 300 meters, represents a significant technical achievement and enhances the versatility of the Bathyscaphe as a timepiece for both adventure and daily wear. It is powered by the Caliber 6054.P, which offers a 72-hour power reserve. This reference is significant for its role in expanding the identity of the modern Fifty Fathoms collection.
