Blancpain Perpetual Calendar Chronograph with Moon Phase – Solid 18K Rose Gold – No. 13

This is haute horlogerie at its most complete. Blancpain, one of the oldest watchmaking names in the world, combines two of watchmaking’s most demanding complications in this watch: a perpetual calendar and a chronograph, finished with a moon phase display.

The perpetual calendar automatically accounts for months of different lengths and for leap years. It shows the correct day, date, and month without manual correction for decades. The cream dial is laid out symmetrically: month and leap-year cycle at 12, day with 12-hour chronograph counter at 9, date with 30-minute counter at 3, and a blue moon phase with gold stars at 6. Applied gold Roman numerals, gold leaf hands, and a perimeter tachymeter scale complete a dial that is both highly functional and classically beautiful.

The solid 18k rose gold case has a stepped bezel and a solid case back engraved “Blancpain No 13”, the watch’s individual number. It’s powered by a self-winding automatic movement and fitted with a brown alligator strap. Case size is 42mm.
