Blancpain Fifty Fathoms 5071-1110-NABA

The Blancpain Fifty Fathoms Bathyscaphe Quantième Annuel, introduced in 2018, is significant for incorporating a highly practical annual calendar complication into a professional-grade dive watch. This reference features a 43mm satin-brushed stainless steel case, a unidirectional black ceramic bezel, and a classic black dial. The annual calendar displays the day, date, and month, and only requires a single correction per year. Powered by the Caliber 6054.P with a 72-hour power reserve, this model masterfully blends the robust, utilitarian aesthetic of the Bathyscaphe with the convenience of a sophisticated calendar, making it an exceptionally versatile luxury sports watch.
