A New Aesthetic for the Perpetual Calendar from Montblanc

Montblanc just unveiled its new Heritage Manufacture Perpetual Calendar Limited Edition 100. This watch features vintage aesthetics, being inspired by historical Minerva wristwatches from the 1940s and ’50s, and a beautiful rose gold case.
Invented in the 18th century, the perpetual calendar complication is a highly complex mechanism that automatically takes the number of days in the month, as well as the cycle of leap years, into account. This way, the perpetual calendar automatically corrects itself for short month, including the 29th of February in leap years. This way, as long as a watch with a perpetual calendar is kept running, it won’t require any manual adjustment for decades. To achieve this, the functions draw on a technical memory of 1460 days, representing four years. To this day, the perpetual calendar continues to fascinate and delight watch enthusiasts, making it a very popular complication.

The Heritage Manufacture Perpetual Calendar Limited Edition 100 indicates the hours, minutes, day, date, month, moonphase, and leap year – and is still a very legible watch. This is due to the large subdials at 3, 6 and 9 o’clock. And the new aesthetic, featuring a brown colour scheme, suits this watch extremely well. The sapphire crystal class box continues the elegant vintage look of this watch.
In line with the design codes of the Heritage line, the Heritage Manufacture Perpetual Calendar Limited Edition 100 comes in a 40 mm rose gold case with curved horns. It is water-resistant up to 5 atm.

This watch is powered by the in-house calibre MB 29.22. This movement with its perpetual calendar complication took Montblanc three years to develop and was introduced two years ago. The calibre comprises 378 components of which 259 are dedicated to the perpetual calendar function. The mechanism allows the user to adjust the watch via the crown in both directions, which is unusual. Also, Montblanc has built in a safety feature, that prevents any setting between the hours of 6 pm and 12 pm, when any manipulation could potentially (and very likely) damage the movement. The movement works at a frequency of 4 Hz and provides a power-reserve of approximately 48 hours.

The Heritage Manufacture Perpetual Calendar Limited Edition 100 is equipped with a brown alligator leather strap, which completes the overall design nicely.

The Heritage Spirit Orbis Terrarum: Montblanc’s new World Timer

Montblanc’s latest offering is a World Timer: The Heritage Spirit Orbis Terrarum.
This watch has a round 41 mm by 12 mm case, which is a resonable size, considering all the information presented by the dial. The bezel is polished and the sides are brushed, as well as the curved lugs.

static.squarespace.comThe center of the dial is sapphire crystal, the continents are half dark, half light, because the 24-hour-dial on the outer perimeter rotates on multiple layers and is visible through the sapphire center, showing day and night. The spaces between the cities and corresponding hours are quite generous, so the watch appears to be rather legible. The actual time is marked by rhodium-plated dauphine hands. The different elements on the dial appear to be spot on at first glance.

Inside the Spirit Orbis Terrarum beats the automatic caliber MB29.20.

The watch is available in stainless steel or 18 carat red gold. The price for the steel version (with a leather strap) is about 5.000 €, for the red-gold version it’s about 13.900 €. For this level of aesthetic quality and in-house manufacturing this is very well-priced.
