New colours and materials for the Fifty Fathoms Bathyscaphe Flyback Chronograph
The two Fifty Fathoms Bathyscaphe Flyback Chronograph models presented by Blancpain each bring a new dimension to the line's emblematic aesthetic codes. The red gold watch with its blue dial stands out for its bold presence on the wrist, while the grade 23 titanium iteration opts for discretion with its anthracite dial. Recently introduced into its collections by Blancpain, grade 23 titanium – also known as grade 5 ELI (extra low interstitials) – is the purest type of titanium available. It notably contains less oxygen than the "standard" titanium used in watchmaking. This reduction in the amount of oxygen improves the metal's resistance to breakage and corrosion. In addition to its unfailing strength, grade 23 titanium is also anti-allergenic and its biocompatibility has made it a favourite in the medical field.
