Among the new Montblanc watches unveiled at this year’s SIHH watch fair in Geneva was the Montblanc Timewalker Chronograph 100, a new chronograph Cheapest Replica Rolex Watches capable of measuring elapsed times to 1/100 second. Here are five pertinent things you should know about this innovative new chronograph from Montblanc.
1. It comes from a manufacture with an impressive chronograph pedigree.
The historic Minerva Manufacture in Villeret, which would later become part of Montblanc, was renowned for its expertise in making chronograph timepieces. In 1916, it launched one of the first mechanical stopwatches able to measure times to 1/100th of a second. Later versions of this timepiece also included a chronograph hand that completed an entire 360° sweep of the dial in just one second. The Montblanc TimeWalker Chronograph 100, a modern iteration of these groundbreaking timepieces, applies and updates this technology with its newly developed manufacture Caliber MB M66.25.
2. The watch has one movement but two balances.
Montblanc’s first big challenge in making a watch that measures intervals with 100th-of-a-second precision was that its movement required a balance that vibrates at a frequency of 360,000 vph (50 hertz). In traditional chronograph Quality Replica Watches UK, one balance drives both the time display and the chronograph mechanism. Activating the “start” function creates a connection between the going train and the chronograph, which is severed when the “stop” function is triggered. Conventional chronograph calibers have a frequency of only 2.5 to 4 hertz.
The solution developed by the watchmakers in Villeret was to incorporate two balances into the movement — a large, heavy screw balance, beating at a traditional 18,000 vph (2.5 Hz) to ensure the precise rate of the going train, and a smaller balance, with the much higher frequency of 360,000 vph (50 Hz) to regulate the chronograph function.
Instead of being in constant motion, the separate balance for the chronograph starts to vibrate only when the “start” function is activated by a flexible, steel plate mounted behind the arrowhead of the chronograph rocker. When the “stop” function is triggered, the plate stops the smaller balance and holds it in place until the next elapsed-time measurement begins.
The chronograph function has its own barrel, which stores enough energy to measure intervals up to 45 minutes long. However, this limit can be extended indefinitely by turning the crown counterclockwise while the chronograph is running, thus adding fresh energy to its devoted barrel. The going train for Sale Best Rolex Replica Watches Online display draws its energy from a second barrel, which stores a 100-hour power reserve.
