Innovation and invention: Greubel Forsey Différentiel d’Égalité explained Revisit the constant force. The irony is that it was the most basic driving force of mechanical watchmaking-the need for precision-that ultimately led to the invention of the quartz watch, which killed the mechanical watch, or so it seemed. The quartz crisis of the 1970s seemed to be the end of mechanical watches. But mechanical performance has entered its second golden age, not as a timekeeper, but as a work of timekeeping art. Few watchmakers have pursued the ideals of timekeeping and craftsmanship as firmly as Koppelfuss. Although the company founded by Robert Greubel and Stephen Forsey is known for its multi-axis tourbillon, the basic principle behind these exotic structures is older: achieving precision. This is why the Différentiel d’Égalité watch was born, which is equipped with a constant force mechanism called remontoir.replica Patek Philippe Grand Complications Watches Continuous invention The foundation of Différentiel d’Égalité is derived from the basic principles of mechanical watches. It starts from the power source, it is the mainspring, essentially a long and coiled metal belt. After winding, the mainspring transfers energy to the gear when it is released. However, the energy produced by the mainspring varies depending on the state of the wind, from excess power when fully wound to insufficient power when almost wound. One solution is to remontoir-from the remonter, or "end"-John Harrison installed his H2 marine chronometer. Remontoir (or remontoire in English) is essentially an additional spring on the gear train, which helps balance the transferred energy by acting as an auxiliary storage and energy source.Replica swiss watches The mainspring sends energy to the remontoire, which is similar to a smaller, shorter mainspring to wind it up. Then the remontoire releases the power of the escapement in turn, and the mainspring is wound again; Harrison's remontoire opens and opens every minute. But because the remontoire spring is very small, the energy it stores and releases is the same, regardless of the energy of the mainspring. The important thing is that the smaller the time interval between tightening and releasing the remontoire, the more energy is released to the escapement. But this is also the Achilles heel of the traditional remontoire mechanism. When the remontoire is released to charge through the balance wheel, the rapid, small burst of energy delivered by the remontoire may interfere with the balance wheel and hairspring. Then the mainspring winds the remontoire, pauses when the remontoire discharges, and then the process repeats-when this happens, it creates a potential surplus and shortage of energy in the gear train.replica luxury watches At the same time, the winding and release of the remontoire will also consume energy (it needs to wind its mainspring, and some will be lost due to friction), otherwise this energy will flow to the escapement. Greubel Forsey's innovation in Différentiel d’Égalité began with the construction of remontoire within the differential, which means that the remontoire spring is connected to a small group of gears, averaging the speed of its constituent wheels. This creates two energy transfer paths within the remontoire-cum-differential: one is used to charge the remontoire clockwork, and the other is used to run the escapement. The energy transferred to the balance wheel is sent in the form of a short time (with each expansion of the remontoire spring) and also follows the swing of the balance wheel. And because the remontoire is combined with the differential, the interference to the balance wheel during the winding of the remontoire per second is eliminated.replica Breitling Endurance Pro Watches Another advantage of remontoire and differential is its lateral structure in the gear train, which means that the wheels of the differential are stacked vertically, making it more compact than traditional remontoire. The first Greubel Forsey remontoire prototype had a 5-second spring. It was shown as a prototype of Invention No. 5 at SIHH in 2008, installed in a quadruple tourbillon movement. Two years later, it appeared in a newly manufactured movement as an EWT (abbreviation for "Experimental Watch Technology") watch, and was housed in a red gold case. EWT is the name named after Greubel Forsey for his experimental watches and prototypes. EWT Différentiel d'Égalité shows that remontoire is working well at 5 second intervals. However, Greubel Forsey did not directly enter the market, but took a step back in its typical way and considered how to further improve the mechanism. Then came the next innovation, the design of the differential so that it can release and rewind every second. One second of remontoire also has the advantage of being able to reflect the operation of the watch.replica AUDEMARS PIGUET Royal Oak Offshore One second is a natural interval because it can double as a beatless second hand. The infinite second is a number of seconds that moves in discrete one-second steps, just like a traditional quartz watch, rather than sweeping over a long time smoothly like most mechanical watches. The final result is the 2018 Différentiel d’Égalité, which has a jump-free second hand and a one-second remontoire. The non-jump second is connected to the one-second remontoire and is displayed in the small sub-dial next to the tilted balance wheel. Just to its right, on a larger sub-dial, is the traditional scanning seconds hand connected to the escapement. In addition to remontoire, Différentiel d’Égalité has several other important functions that help improve timing. The most obvious is that the balance wheel is tilted 30 degrees from the horizontal. According to Greubel Forsey's research, it minimizes the gravity error when swinging.High Quality Replica watches First, the watch is equipped with a hacking function, or balance brake, a lever to stop the balance wheel, and the hands of the watch. The second function runs at the same time as the brake-the zero-returning second returns the second hand to the 12 o'clock position. Together they allow time to be set in seconds. Although these two functions have been found in other watches (most notably in several Lange watches), no one has performed hacking and zero-seconds as meticulously as Guberfors. In Différentiel d’Égalité, a series of extra-wide, gorgeous black polished steel horizontal planes are cut and reset together with an extra-large heart-shaped cam. The glossy finish applied to the relatively unremarkable hacking reset seconds illustrates the key quality that distinguishes Guberfors from many of its peers-finishing. Its watches have the best hand-finished craftsmanship in the industry, especially for larger independent brands. The largest department in the company is dedicated to manual finishing. More than 20 craftsmen are responsible for decorating and assembling the parts of 100 watches every year. On average, a craftsman only needs to complete the components of five replica men watches. |
