Movement

Available in steel or red gold versions, the Fifty Fathoms Automatic houses an all-new mechanical movement
entirely developed by Blancpain and exclusive to the brand. The self-winding Calibre 1315 is derived from the
hand-wound Calibre 13R0 presented in October 2006. Stemming from a lengthy quest for simplicity, precision
and performance, it was conceived right from the outset to equip watches with a resolutely sporting vocation.
Blancpain has fitted it with an extremely dense bimetallic rotor ensuring excellent winding efficiency.

In addition, this movement features most of the characteristics that made the 13R0 such a truly exceptional calibre,
including its free-sprung balance with no index and no swan’s neck, equipped instead with regulating screws
placed around the rim of the balance. This screw-based system provides ideal for a sporty watch, since it avoids
the potentially detrimental effect of shocks that could modify the position of the index or the swan’s neck, thereby
disturbing the rate.

To ensure accurate and efficient adjustment, Blancpain has equipped it with square-headed gold micrometrical
screws, enabling the watchmaker to easily visualise the corrections he is making. Governed by a concern for
optimal sturdiness, the balance is crafted from glucydur, which is heavier than the titanium used in the 13R0.
