The Montblanc Heritage Spirit Perpetual Calendar is the flagship piece of the Montblanc Heritage Spirit Collection. It manifests the values of the Montblanc Meisterstück and embodies the finest Swiss watchmaking in every detail. The high complication of the perpetual calendar always displays the correct date without needing to be corrected by hand, including for months with less than 31 days and for leap years. It is easily regulated by 4 individual pushers. Faceted hands in the classical dauphine shape combine with faceted appliques of different lengths and an applied Roman numeral “XII”. The cambered silver-white dial has been tastefully embellished with a sunburst pattern. The elegant 39 mm case with its contemporary straight lines is accentuated by a horizontally drawn satin finish on the middle piece. The caliber MB 29.15 can be admired through the sapphire crystal case back. The Montblanc Heritage Spirit Perpetual Calendar is produced in-house in the Montblanc Manufacture and certified with the Montblanc 500 hours quality certificate.
