Informed by legendary Minerva classic timepieces from the 1940s and 1950s, the Heritage model family blends the beauty of watchmaking's history with modern design ideas and quality. The Montblanc Heritage Chronometrie is a really unique watch. It is blessed with the calibre MB M62.00 whose last 38 historical pieces have been seen in the archives of the Manufacture. The historical calibre MB M62.00 is informed by the Minerva Pythagore calibre from 1948 with its very lovable special shape. It was remade in 2003 with more special shapes and unique looks.
