Inspired by historical Minerva classic wristwatches from the 1940s and 1950s, the Heritage product line combines the elegance of watchmaking's past with today’s bold design codes and technology. The Montblanc Heritage Perpetual Calendar Limited features a brand-new manufacture movement, the caliber MB 29.22, which indicates the hour, minute, day, date, month, moonphase and leap year in an extremely legible way thanks to its large counters at 3, 6 and 9 o’clock. The self-winding movement with a 48-hour power reserve is also equipped with a very practical dual-time function and a 24-hour indicator, which are particularly useful when traveling. The Montblanc Heritage Perpetual Calendar comes in an elegant 40 mm case made of stainless steel which is highlighted by refined curved horns, a domed sapphire glass box and a distinctive silvery-white dial.
