When launched in 1953, the first Fifty Fathoms quickly stood out thanks to its practical features, entirely designed for professional diving. Among the decisive criteria that contributed to its renown were broad luminescent hour-markers and hands contrasting with a black dial and unidirectional rotating bezel, as well as a steel case with a soft iron inner cage intended to protect the movement from magnetic fields.
In 2007, the Fifty Fathoms was updated and enhanced with a date placed between 4 and 5 o'clock. Today, Blancpain is offering a new version of this Fifty Fathoms Automatique model which combines its ebony-black color with a satin-brushed titanium case.
Robust and highly resistant to impacts and corrosion, titanium also has a low density that makes it particularly light. This major advantage, which distinguishes it from steel, has enabled Blancpain to produce a large-diameter model, offering all the technical guarantees of a diving instrument without having to feel them weighing on the wrist.
The case measures 45 mm in diameter and 15,4 in thickness and is water-resistant to 300 meters. Its ratcheted unidirectional rotating bezel is fitted with a scratchproof domed black sapphire insert. For enhanced visibility, its markers, dial hour-markers and hands are made of Super-LumiNova®, a coating that strikes an ideal contrast with the sunburst black face of the watch.
The sapphire crystal case-back provides a beautiful view of the Blancpain 1315 caliber. Its five-day power reserve is ensured by the use of three series-coupled barrels housing high-performance springs. Its silicon balance-spring protects it from the negative effects of magnetism without the need to isolate it behind a metal cage and its meticulous finishing combines straight-graining, beveling, circular-graining and circular satin-brushing techniques.
