A Fifty Fathoms 'Barakuda' featuring tritium and red two-tone indices for improved legibility. Born of the collaboration between Blancpain and the French Navy with the aim of providing a more functional diving tool, the Fifty Fathoms featured numerous novel innovations now common to the category. The Barakuda dial variant was produced in only 150 examples, a number of which served as military issued equipment. This example sports engravings from service in the Polish Navy despite being first engineered for Germany's. With its high-legibility red indices, utilitarian appearance, and issued pedigree, the Barakuda has proven incredibly alluring now, decades later, for collectors.
