Les Secondes au Centre Retour-à-Zéro

Limited jubilee edition with two newly developed watch movements: Montblanc Collection Villeret 1858

In 2008. the {$Title} Collection Villeret 1858 Les Secondes au Centre Retour-à-Zéro represents the launch of a group of exclusive timepieces designed to commemorate the founding of the Minerva manufacture 150 years ago. and from which the current “Institut Minerva de Recherche en Haute Horlogerie” has evolved.

As an interesting innovation. inspired by the company’s garde-temps philosophy Handbags Replica. the Montblanc Collection Villeret 1858 now includes two new. specially developed movements with a “Retour-à-Zéro” function that makes it easier to set the time exactly to the second. It is probably the first automatic zero-resetting mechanism with a large. solid central seconds hand. When the winding crown is pulled out Replica Watches. the seconds hand is automatically returned to zero and locked in this position while the hour and minute hands are set to the correct time. If the crown is pushed back into the case on the last tone of a time signal. the watch restarts exactly to the second.

The automatic resetting mechanism requires subassemblies that are similar to those found in a chronograph. The seconds hand. for instance. is mounted on a large fourth wheel. which is connected to the drive wheel by a horizontal clutch. On the other hand. the winding stem needs to be linked to a lever mechanism. When the crown is pulled out. the mechanism first releases the horizontal clutch and then. with a hammer. moves the large fourth wheel on the seconds hand via a cam to the zero position and fixes the seconds hand in this position.

Each of these steel levers is carefully chamfered HandBags Replica. and has hand-shaped sides and fine. satin-finished surfaces. As with the chronographs. the “Mise en Fonction” for the zero-resetting mechanism is carried out meticulously by hand. every single part of each movement being aligned with the others to tolerances of a hundredth of a millimetre.

The new movements are known as the 16.18 calibre for the “Grande Seconde au Centre Retour-à-Zéro” model with its 47 mm case and the 13.18 calibre for the slightly smaller 41 mm “Seconde au Centre Retour-à-Zéro” model. Theyare classic slow oscillators and feature large. heavy screw balances with a frequency of 18(Replica Marc Jacobs).000 beats per hour (2.5 Hz). which breaks down time into fractions of one-fifth of a second.

The plates and bridges are made of rhodium-plated German silver. the bottom plate is circular-grained on both sides. while the bridges are chamfered by hand and decorated with circular-graining and Geneva stripes (Côtes de Genève) on the top surface. All the pinions have polished faces. arbors and wings. Like all the other calibres in the Montblanc Collection Villeret 1858. these two movements will also be limited in the course of the next few years to 288 (2 x 144 = 2 x 12 dozen = 2 gross) before production is permanently discontinued. The tools machined specially for these movements will then be stored away. so that original spare parts can be made at any time Fake Handbags. as required.

Limited editions in platinum and gold

As a tribute to Minerva’s foundation in 1858. the watches in the {$Title} Collection Villeret 1858 Les Secondes au Centre Retour-à-Zéro will be produced in a strictly limited edition in accordance with the 1/8/58 formula: Unique watches in platinum. editions of eight watches in 18 ct. white gold and 58 pieces in 18 ct. rose- gold. The white and rose-gold watches feature hand-guilloched gold-leaf dials with the typical grooved patterning that creates such a fascinating play of light. As an additional exclusive feature Replica . the unique examples in platinum have black mother- of-pearl inlays Replica Handbags. which. depending on the incident light. shimmer in all the colours of the rainbow. The cases are polished on all sides and have a convex bezel holding high-domed sapphire-glass with sharp vertical sides. Closing firmly over the screw-in sapphire-glass back cover is a hinged cuvette that is released using a patented mechanism invisible from the outside and mounted on the horns for the wristband.

On the outer surface are the engravings “Edition Limitée”. “Montblanc” and “Fait main à Villeret” (handmade in Villeret). The inside of the cuvette bears the inscription “Demetrio Cabiddu Maître Horloger”. the name of the Technical Director at the “Institut Minerva de Recherche en Haute Horlogerie”. who oversees the development of the mechanical movements found in these watches. The movement can be seen behind the sapphire-glass back cover. with its gold-plated engraving: “Minerva Villeret”.

There too. of course. is the {$Title} symbol. signifying the highest mountain in Europe with its six glacial tongues. It can be found as an inlay. made of genuine mother-of-pearl. in the winding crown of the new watches.

As precious as a movement: The hand-guilloched dials of the white and rose-gold models

The watches in the Montblanc Collection Villeret 1858 Les Secondes au Centre Retour-à-Zéro feature solid-gold dials. whose hand-guilloched decoration bears witness to another watchmaking tradition. A finely grooved clou de Paris pattern runs around the edge of the dials on the white and rose-gold models. while the centre is decorated with a guilloche in the form of the Montblanc symbol. On the unique platinum models Replica Watches. the edge and centre of the dial are set with black mother-of-pearl(Christian Dior HandBags Replica). while a delicately guilloched circular pattern decorates the rhodium-plated gold surfaces between.

Classical guilloche work is a machining technique used to apply a regular grooved pattern to a metal surface. which creates an enchanting. shimmering effect. Although created using a machine. it is still considered to be a classical watchmaking craft. because the turning motions and the positioning of the cutting template are carried out by hand. The more delicate the desired guilloche. the more precise the individual steps in the operation of the machine need to be. This is why it takes so many years of experience before a craftsman has the skill to guilloche dials like those on the {$Title} Collection Villeret 1858 Les Secondes au Centre Retour-à-Zéro with the required degree of accuracy. Only dials like these can rightfully be called “hand-guilloched”. If a dial is simply referred to as “guilloched”. we can assume that it has been carried out entirely by machine without the artistic craftsmanship of the true guillocheur. By contrast. the dials used for the gold watches in the Montblanc Collection Villeret 1858 Les Secondes au Centre Retour-à-Zéro can be proud to bear the inscription GUILLOCHE MAIN SUISSE.
