Fifty Fathoms Grande Date

Share

Since the debut of the modern Fifty Fathoms in 2007, date indications have appeared through a window placed at the 4 o’clock position. Now for the first time, Blancpain has brought its signature instant-change large date complication to the Fifty Fathoms, displayed in two windows located at 6 o’clock.  

Blancpain’s large date mechanism has been a feature of several models in the Villeret Collection. In addition to the enhanced readability due to the large size of the numerals, its design changes the date instantly at midnight without excess energy consumption from the running train of the watch. Those advantages have been brought to the new Fifty Fathoms Grande Date. The large windows have been placed at 6 o’clock, with the date adjustable via the crown.

The new model retains Blancpain’s base caliber 1315, which is 100% in-house like all Blancpain movements. The 1315 is equipped with three mainspring barrels and achieves a five-day power reserve. The use of a non-magnetic silicium hairspring protects the movement from magnetic fields without the need for an inner soft iron case. Thus, the movement of this Fifty Fathoms can now be admired through a clear sapphire case back.

The 45 mm satin-finished titanium case has been fitted with the traditional Fifty Fathoms unidirectional rotating bezel. Fashioned in sapphire, which only diamond surpasses in hardness, the domed bezel offers extraordinary scratch resistance. Consistent with its diving heritage, the new Fifty Fathoms Grande Date is offered with a sail-canvas or NATO strap.
