Second precision Recently, the first Richard Lange Jumping Seconds Platinum 950 watch has been delivered to the Lange global specialty stores and retailers. This watch was launched at the 2016 Geneva watch show, a total of 100 pieces. Lange reinvented the fascinating Science Observatory table with his classic timepiece dial, second-hop device, constant-power escapement and zeroing device. Lange Watch and RICHARD LANGE JUMPING SECONDS with seconde morte For 10 years, Richard Lange has represented a growing collection of watches. The Richard Lange Series is well adapted to keep Lange's traditional scientific chronometer flexible with the times. It pays special tribute to Fernando Adolph Lange, the eldest son of Ferdinand. Born in 1845, Richard Lange inherited his father's heritage and turned the latest observations in contemporary physics, chemistry, and mathematics into many innovative technologies. All patents obtained by him can be reflected in the pocket watch elaborately made by the watch factory. Launched in January 2016, Richard Lange Jumping Seconds adds a watch with the Longue Classic pocket watch to the collection. Newly developed L094.1-type self-made movement with second-second sophisticated functions (also known as seconde morte), and equipped with Lang's patented constant power escapement system. This device uses the switching power of the skip-second device in the gear train to provide new energy for the constant motion hairspring of a constant power escapement. In a separate wheel train between the barrel and the escapement, the constant power unit compensates for the progressive reduction of the power of the spring. This keeps the watch in constant torque and steady amplitude for up to 42 hours of power reserve. Zero reset device makes the watch can be synchronized with the time signal quickly and smoothly. The top of the silver-gray hourglass dial features a striking seconds ring lined with a platinum 950 case measuring 39.9 mm in diameter and elegant in style. Clock circle and the second circle at the intersection of small windows set, ten hours before the watch power is depleted in red, to remind the wearer to watch the chain. Carefully decorated by hand inside the movement, in line with the most stringent Lange standards, and wearers through the sapphire crystal bottom cover, watch movement operation. The Pentagram controls the skip-second device, under a transparent sapphire bearing, and runs on a mirror-polished end piece. In addition, 3/4 plywood hollow Department also allows the wearer to watch the constant dynamic power escapement system constant hairspring, zero device lever, balance spring, the clutch is also clearly visible. Constant Jump Seconds Richard Lange Jumping Seconds Technical Information Additional Richard Lange Jumping Seconds Simple and flawless timepiece dial, hidden in three major technical characteristics: watch named after the second device to ensure that power and stability of the constant power escapement, and reset the second hand reset device . Understanding these three major features provides the foundation for a deeper understanding of the Lange movement L094.1. RICHARD LANGE JUMPING SECONDS Lange pocket watch with seconde morte unit Jump second device The second device is Lange nearly 150 years since the tradition. In 1867, watchmaker Ferdinand Adolph Lange of Saxony created a pocket watch with a seconde morte. Pocket watch with a large sweep second hand, a minute clearly divided into 60 steps. The second hand can start, stop, but can not be reset to zero. The Richard Richards and Amy Innovations, the children of Adolphe Lange and Ferdinando, applied for a patent on their 3/4 splint installation in 1877, titled "Seconds with a second-second movement ". Richard Lange Jumping Seconds, launched in January 2016, has a similar principle of operation to that of the original: In this historic installation, the second-second was controlled by a jerk long lever and a star gear to convert the balance amplitude of six times per second to The second hand beats a grid of power. Modern second-second device The star gear running under the transparent ruby ​​bearing is connected to the escapement wheel spindle, rotating along with the escape wheel at one revolution along the axis every five seconds. Every second, the horns of the star gear release the tensioned levers, creating what the watchmaker refers to as "sudden beats." The lever instantly rotates 360 degrees and is stopped by the next corner of the star gear. This series of moves make the second hand a precise move. Lange homemade L094.1-type movement Constant power escapement system The initial torque of the mainspring but the last paragraph of the torsional torsion weak, the formation of the difference, Lange unswervingly explore ways to solve the problem. Lange has developed four different constant power transmission systems, including the sesame chain drive system started in 1994, and three different constant power escapement systems. The constant power escapement in the Lange 31 maintains the same torque every ten seconds over a 31-day period; Zeitwerk uses a strong mainspring to propel the digital disk instantly, while the constant power carried in Richard Lange Jumping Seconds Escapement system device is to play two major functions: to compensate for the gradual decline of the power barrel, while reducing the amplitude of jumping seconds. This device uses the switching power of the skip-second device in the gear train to provide new energy for the constant motion hairspring of a constant power escapement and the escapement to be viewed through the bridge of the gear train bridge. In a separate wheel train between the barrel and the escapement, a constant power escapement compensates for the gradual reduction of the power of the spring. The constant motive spring of the constant power unit gives the constant torque of the escapement, thus ensuring that the watch is stable in amplitude over a 42-hour power reserve. Free-swinging gossamer as constant motif silk with the Lange watch factory self-made, with the cam fixed balance of coordination, to ensure that the rate of stability. Zero device The zero-resetter, originally fitted to the Sax-0-Mat movement in 1997, is now modified and housed in Richard Lange Jumping Seconds with a clutch of multiple discs. Its function is to use a high moment of inertia to stabilize the operation of large seconds hand, especially in the sudden start and stop the jump phase. The clutch also separates the wheel train when the reset second hand returns to zero. RICHARD LANGE JUMPING SECONDS zeroing device After lifting the crown, the complicated lever system activates three programs in an instant: stop the spring against the balance wheel and secure it, and the clutch disk is separated by the clamp lever, separating the seconds hand from the wheel train. Reset the hammer to contact the heart cam so that it and the second hand advance toward the zero seconds position. When the crown is pressed back to its original position, the second hand will be reconnected with the wheel train, the balance wheel will also be released and then swung again.
