The Bohème timepieces feature polished cases with slightly curved and faceted horns, sculpted onion crowns and bezels set with sparkling diamonds. The dials are crafted with traditional decorative techniques, such as guilloché and gem-setting, and include leaf-shaped hands, floral Arabic numerals, minute scales with raised dots and internal hour rings, all enhancing the refinement of each model. The moon phase complication is a recurrent feature in the Bohème product line, displaying the portion of the moon that is lit by the sun and that can be viewed from Earth. This romantic and practical complication is one of the earliest horological complications and continues to delight women today as it did centuries ago.
The new Bohème Manufacture Perpetual Calendar welcomes a brand-new in-house perpetual calendar, the calibre MB 29.22, that indicates the hours, minutes, day, date, month, moon phase and leap year in an extremely legible way thanks to its large counters at 3, 6 and 9 o’clock. The movement took three years to develop and is composed solely of wheels, in contrast to most perpetual calendars that use levers. This enables the user to adjust the watch via the crown in both directions, making it far simpler to set.
In addition to this, another new safety feature developed by the Montblanc movement engineers prevents the user from setting the watch between the hours of 8 pm and 12 pm, when any manipulation could damage the movement as the correctors are locked. The new Montblanc Heritage Perpetual Calendar is powered by a self-winding movement with a 48-hour power reserve and is also equipped with a very practical dual-time function and a 24-hour indicator, which are both very useful when travelling. Housed in a new 38 mm case set with 58 diamonds, the new Montblanc Bohème Manufacture Perpetual Calendar comes in a choice of steel or red gold and is certified by the Montblanc Laboratory Test 500. The gold version is limited to 100 pieces.
