Meisterstück Heritage Perpetual Calendar

 
Sharing the Passion for Fine Watchmaking
 
Ninety years ago, Montblanc created a writing instrument that became an icon in the culture of writing: the Montblanc Meisterstück. With functional and aesthetic design, an innovative ink supply and a manually profiled gold nib, this fountain pen is the legendary writing instrument of our time.
 
The Montblanc Meisterstück Heritage Collection is inspired by the ninety-year heritage of the Meisterstück. With classical design, discriminating complications and sumptuous decorations, these elegant timepieces manifest the values of the Montblanc Meisterstück and the traditional features of fine Swiss watchmaking in every detail – thus making them their owners’ lifelong companions.
 
Timeless Aesthetics – Eternal Functionality
 
The grande complication of the perpetual calendar is both highly demanding from a mechanical viewpoint
and an expression of the utmost in the watchmaker’s art. Unlike an ordinary “full calendar”, a perpetual calendar always shows the correct date and requires no manual adjustment, not even at the end of a month with fewer than 31 days and also not at the end of February in a leap year. It accordingly jumps directly from 30 June to 1 July and from 28 February to 1 March, except in a leap year, when it automatically shows 29 February. The mechanism which supports this function requires complexly shaped rockers and cams that mechanically pre-program the variously long months and also add a 29th day to February once every four years. If the mainspring of the Montblanc Meisterstück Heritage Perpetual Calendar is kept sufficiently wound, this timepiece’s calendar will require no manual adjustments until the year 2100. If this watch is left unworn for a longer period of time, its calendar displays can be quickly and easily returned to synchrony with the current date by pressing the inset buttons in the middle piece of the case. The perpetual calendar is powered by self-winding mechanical Calibre MB 29.15., which has a balance paced at 28,800 semi-oscillations per hour (4 hertz).
 
The displays of the Meisterstück Heritage Perpetual Calendar are harmoniously arranged on the dial: the date is shown at “3 o’clock”, the day of the week at “9 o’clock”, and the month at “12 o’clock”. On the inner scale of the month display, the leap-year cycle is shown by a blue triangle and a leap year is indicated by a red “4”. The moon’s phases are emulated in a window at “6 o’clock”; the moon’s age is indicated in days at this window’s upper edge. The calendar’s finely blued hands elegantly contrast with the silver-white, cambered dial, which is adorned with a sunburst pattern. A gold-plated hour-hand and minute-hand harmonize with the 39-mm-diameter case, which is crafted from 18 karat rose gold. A pane of sapphire crystal in the back offers a clear view of elaborately embellished self-winding Calibre MB 29.15. This new classic wristwatch is affixed to a black alligator-leather strap with an 18 karat rose gold pronged buckle. The closure’s curved crosspieces harmoniously repeat the curvature of the watch’s case. This too is another of the many details that distinguish timelessly perfect design in full accord with the traditions of haute horlogerie.
 
Each Montblanc Meisterstück Heritage Perpetual Calendar wristwatch is subjected to a comprehensive 500-hour quality test at the manufacture in Le Locle. Developed by Montblanc, this rigorous examination verifies the accuracy of the watch’s rate, the watertightness of its case, the timepiece’s overall performance and robustness, and the functionality of the individual displays. Only after its examiners are convinced that a watch upholds Montblanc’s strict quality standards do they release it for subsequent delivery. Each watch that passes the 500-hour test is individually issued a test certificate.
