Blancpain Fifty Fathoms 5100-1127-NAJ Description

This is the Blancpain Fifty Fathoms Bathyscaphe 38mm. Its significance lies in offering the clean, modern aesthetic of the Bathyscaphe in a versatile, mid-sized case that appeals to a wider range of wearers and preferences for classic proportions. Introduced in 2017, this stainless steel reference features a captivating sunburst blue dial with a matching blue ceramic bezel, providing a distinct and elegant look. It retains the full 300m water resistance and dive functionality of its larger siblings. The watch is powered by the Caliber 1151, a slim automatic movement with a 100-hour power reserve, which allows for the watch’s slender profile. This model is a core piece in the collection, balancing tool-watch capability with everyday elegance.
