After the preview of Greubel Forsey revealed, QP EQUATION has real first novelty in SIHH 2014. When a fan of Haute Horlogerie feels appointed for perpetual calendar, his pupils dilate at once. If at that point were to come out even” equation of time “fainting is almost assured. In addition to being two of the finest horological complications ever, both embody the challenge of mechanics to the measure of the time in the long term.
For Robert Greubel and Stephen Forsey fantastic Atelier which is based in La Chaux-de-Fonds. Instead of acting towards classical correctors placed on the case middle, just pull out the crown, set “QP” or “H: M” mode by checking that the indicator appears on the dial at 2 o’clock and adjust without going crazy all functions always just turning the crown in both directions, or set the time. It seems little, but considering that most of the watches you see on the wrist — even those that have the snap never have the date set for “one of those” must also distinguish the actual length of the day during the year , have the calendar set well is essential.
Simple outside, inside is obviously very complicated. To move the indications on the dial are a long series of cams with teeth implants furniture: the whole mechanism is integrated into the movement, which only makes it all the more remarkable that it does not increase the size. As already mentioned, the equation of time is tied for life to calendar: where is the first, the finest, if not provided could be the other. The cam that controls the year with leap year cycle is also used to indicate the season, in which QP to EQUATION is visible from the bottom. Unfortunately at the moment I write the material being giuntomi print before the SIHH 2014 in addition to the ones you see there are no other images available.
Equation of time
And ‘one complication or function that allows you to measure mechanically the actual duration of the day , being the Earth’s orbit around the Sun elliptical undergoes in the course of daily changes ranging from a few seconds to a maximum of 16 minutes . By convention, a day always lasts 24 hours, but the real time is the solar time.
Continuing blindly to base myself on the description of EQUATION QP to the bottom you can read the time of the year shown in the four figures, the leap year is visible on the dial with day, date and month. The information is provided due to two discs in synthetic sapphire transparent. The first is driven by the wheel of date and has a minute scale to indicate the difference between solar time and mean time. The second disc, which makes a full turn in a year, is divided into four sections in red and blue to indicate whether the ’ equation of time is positive or negative. To discover it, it should be noted on the dial where the red line (positive difference) or the blue line (negative difference) crosses the scale.
We must say, a choice to represent the ’ equation of time is very unusual when normally only used a hand that describes an area of 8 minutes more, or less. That of Robert and Stephen also allows you to realize the exact point of the elliptical orbit that the Earth is going through seizing equinoxes and solstices and consequently at what point of the season you are or what is missing.
