Along with the new Blancpain Bathyscaphe Day Date 70s limited to 500 pieces —featured here—, comes the new Blancpain Fifty Fathoms Bathyscaphe Annual Calendar —Quantième Annuel. This is the first time that this model is equipped with such complication. This year’s Bathyscaphe Quantième Annuel brings new functionality to the sport collection, trying to enhance its use as a daily wearer. Including indications for the day of the week, date, and month shown in rectangular apertures at 12 o'clock and with a gorgeous old-school looking blue moonphase indicator at 6 o'clock, the date indicator takes a prominent spot with its chapter ring and its red quarter moon tipped hand.
