This Fifty Fathoms Bathyscaphe Flyback Chronograph is the quintessential stainless steel version of the model, first introduced in 2014. Its significance lies in the debut of the advanced in-house Caliber F385 within the versatile Bathyscaphe case. The F385 is a high-frequency (5Hz) integrated flyback chronograph with a column wheel and vertical clutch, representing a major technical advancement for Blancpain. Housed in a 43.6mm steel case with a black ceramic bezel and black dial, this reference offers a classic, robust, and highly capable luxury dive chronograph. It has become a core model in the collection, perfectly balancing historical design cues with modern, high-performance watchmaking.
