A new interpretation of Rieussec’s chronograph from 1821
Nicolas Rieussec’s first patented chronograph from 1821 inspired the watchmakers at Montblanc to create the Nicolas Rieussec watch collection with manufacture movements and distinctive styling. The timepiece’s unmistakable appearance combines an off-centre hour-circle in the upper part of the dial and the chronograph’s elapsed-time displays in the lower portion of the face. As on the original from 1821, elapsed time is shown on two rotating discs, above each of which a motionless hand indicates the passing seconds and minutes.
In 2014, Montblanc pays tribute to this great clockmaker with a new interpretation of his chronograph from 1821. The Montblanc “Homage to Nicolas Rieussec” chronograph faithfully replicates every detail of the colour scheme and the styling of the hands as they appeared on the original “time writer”, but relies on innovative materials and technologies to transport the historical device into our contemporary day and age. The new “Homage to Nicolas Rieussec” chronograph from the Montblanc Nicolas Rieussec collection shows the date, indicates the time in two different time zones and also offers a day/night display.
Traditional features – innovative styling
In an unprecedented innovation, the chronograph’s hand is designed as a double index: each of the two tips of an elongated horizontal blued-metal rhombus points to a calibrated scale on one of two rotating discs. Each index is shaped exactly like the ink carriers on the original chronograph from 1821. The two whitelacquered discs – one at the left for 60 elapsed seconds and the other at the right for 30 elapsed minutes – are likewise inspired by the appearance of the original timepiece.
At first glance, the watch’s hour-circle seems to lack hour numerals and to bear only a minute-scale. With
slim black strokes alternating with Arabic numerals at ten-minute intervals, the minute-circle faithfully emulates its counterpart on the original “time writer”, the position of the hands allows precise legibility of the hours.
The hour-circle reveals its special feature in the dark, when an unprecedented technique causes the formerly hidden hour numerals to appear on the dial. The traditionally styled hour-circle is crafted from ultramodern hybrid ceramic permeated with Superluminova pigments. These luminous pigments form the Arabic hour numerals in the characteristic font of the Montblanc Rieussec collection. The digits are invisible in daylight because they’re precisely embedded into the hour ring, with which they share exactly the same colour. But when the ambient light starts to dim, the luminous pigments that fill the numerals – as well as the Superluminova-filled hour-hand and minute-hand – begin to glow, thus assuring perfect legibility and simultaneously giving this watch its characteristic appearance.
The pale, shiny, enamel-like surfaces of the hour-circle and the chronograph’s discs create an unusual contrast with the fine-grained (grainé) texture of the dial. Two apertures rimmed by finely satin-finished gradations offer an unobstructed view of the date display at “3 o’clock” and the finely guilloche-embellished day/night indicator at “9 o’clock”. A skeletonized hour-hand indicates the time in a second time zone.
A monopusher chronograph with a manufacture calibre
Combining traditional watchmaker’s craftsmanship and modern engineering artistry, self-winding mechanical manufacture Calibre MB R200 ticks unseen beneath the innovative dial. A laboriously milled column-wheel controls the monopusher chronograph; the connection between the gear-train and chronograph’s wheels is alternately engaged and disengaged by a vertical coupling, which functions nearly without wear and prevents the elapsed-time hands from jumping when the chronograph is switched on. The double barrel stores enough power for 72 hours of continuous running. The movement’s appeal derives not only from its outstanding mechanical performance, but also from its horological aesthetic. The components are decorated with Geneva waves and have beveled, polished edges. Bright red jewels, blued screws and shiny golden brass wheels complete the handsome ensemble, which can be admired by peering through the transparent pane of sapphire crystal in the back of the case.
The dial is protected by a slightly cambered sapphire crystal that’s been antireflective treated on both its surfaces. The movement is ensconced inside a circular case. The case’s doubly stepped horns angle slightly downward so the 43-mm-diameter watch fits ergonomically and conforms to the anatomy of its wearer’s wrist. A watch connoisseur who notices the unconventional positioning of the chronograph’s button at “8 o’clock” will correctly deduce that this is a monopusher chronograph which can be conveniently operated with the tip of the right thumb. The crown is deeply grooved and embellished with a domed black-and-white Montblanc emblem. A pin buckle secures the alligator-skin strap, which conforms to the curvature of the horns and the roundness of the case.
The Montblanc “Homage to Nicolas Rieussec” chronograph will be available in a limited edition of 565 steel timepieces.
