Ludwig van Beethoven is world – renowned for his works – Fifth Symphony(Fate Symphony) in which the four – note prelude is a highlight. The new release – Lange Zeitwerk Striking Time Collection will turn a new leaf in the history of Lange. The wristwatch gives off a high pitch every fifteen minutes and a lower pitch on the hour. Historically, the wristwatch is a first that is fitted with musical sound timekeeping function, yet not by chance for it was intended for the new era in combination of its extraordinary design features as well as watch – *** idea of breaking fresh ground about two years ago. And its mechanical design concept is the very precondition of its integrated automatic sound gear train.In the precision watch***, every quarter timekeeping function which can be started and turned off at any time is rare yet absolutely practical. You just need to press the button at the 4 o'clock position to turn the time announcing device to mute. What's more, the quiet mode can be affirmed simply by seeing whether the mallet deviates from the sound spring through the sapphire crystal. To pull out the crown can reset the mallet so that the time set is available, and the time announcing device won't be started or disturbed by accident.The jumping dial faultlessly embodies the *** style of the Lange Zeitwerk Striking Time, *** the time display clear at a glance. Its case is 44. 2mm wide. Fitted with the self – regulating L043. 2 manual movement, the watch is able to provide a 36 – hour power reserve. Its case is available in either 18K white gold or platinum, and the platinum style is offered as a limited edition of 100 pieces worldwide. In addition to those with black dial matched with white gold case, the 100 limited – edition watches are with rhodium – plated dial. With innovative technology and outstanding timekeeping performance, the Lange Zeitwerk Striking Time certainly will become the observed of all observers. Surely, it is an example of divine inspiration.

The fourth A. Lange & Sohne "Pour le Merite" watch, an outstanding collector's masterpiece, boasts a fusee-and-chain transmission and a tourbillon with a patented stop-seconds mechanism. Both horological complications improve rate stability and precision. The one-of-a-kind regulator dial of the watch reveals a fascinating pivoting segment. It was inspired by a famous historic highlight of the brand. The creation of the Richard Lange Tourbillon "Pour le Merite" watch is closely related to Johann Heinrich Seyffert (1751-1817), a prominent watchmaker, the one who greatly contributed to the progress of precision horology in Saxony. Seyffert's timepieces enjoyed great success at the royal court and among scientists. The famous explorer and naturalist Alexander von Humboldt was also among the admirers of the watchmaker's creations. He used a Seyffert chronometer during his expedition to South America. According to the explorer's notes, the chronometer provided accuracy to four or five seconds a day. When it was kept stationary, its rate accuracy was even better - to less than one second in 24 hours. Even today, such level of precision is truly impressive. The regulator pocket watch crafted by Heinrich Seyffert in 1807 is worth special attention. The watch is a fine reflection of the watchmaker's quest for horological perfection. It presently belongs to the collection of the Mathematics and Physics Salon in Dresden. The dial of the regulator watch is completed with three intersecting circles for the time indications. The caliber of the watch incorporates a fusee-and-chain mechanism providing the constant transmission of power. The timepiece, bearing the serial number 93, served as the blueprint for the Richard Lange Tourbillon "Pour le Merite" watch. The face of the new A. Lange & Sohne watch demonstrates three overlapping off-centre circles. The biggest is the minute circle. The slightly smaller sub-dials are for the seconds and hours. The dial layout has been inspired by the precision regulators, used since the 18th century for calibration by timekeeping services, observatories and manufactories for synchronizing new timepieces. The round cut-out in the seconds sub-dial is traversed by the minute scale and by the recessed tourbillon bridge. It shows off the tourbillon cage. It is interesting to mention that the tourbillon is presented in its entirety only in the period from 12 to 6 o'clock. At 6 o'clock, the dial segment completed with the Roman numerals VIII, IX, and X instantaneously pivots into the aperture, thus *** the hour scale complete. The ingenious switching mechanism is used to generate this motion. It is responsible for the dial segment to be advanced by 90 degrees in increments of six hours. It means that the timepiece tells the time unambiguously during the morning and the evening hours.At 12 o'clock, the hours dial segment instantaneously vanishes and the tourbillon is exposed in all its beauty for the six hours to come. With help of a patented stop-seconds mechanism, it is possible to simply halt the tourbillon by pulling the crown, so the time can be set to one-second accuracy. On the case-back side, the tourbillon is found in a diamond endstone secured in a screwed gold chaton. The same noble setting highlighted the iconic Lange pocket watches relevant to the manufactory's highly-esteemed "1A" quality category. The unique fusee-and-chain transmission, a smart implementation of the principle of levers, is responsible for equalizing the gradually waning force of the mainspring and maintaining the effective torque, this way also maintaining the constant amplitude of the balance, during all 36 hours of the power-reserve. The planetary gearing makes this constant force delivery kept with no interruption even when the timepiece is being wound. The heart of the Pour le Merite watch, the novel hand-finished Lange manufacture calibre L072.1, 33.6mm in diameter, with a frequency of six semi-oscillations per second, a classic screw balance, and a recalculated balance spring, is synonymous to the utmost in precision. The exceptional A. Lange & Sohne Richard Lange Tourbillon "Pour le Merite" watch features a stately platinum or pink-gold case that measures 41.9mm in diameter. It is coupled with a hand-stitched crocodile strap.The platinum version of the timepiece is strictly limited to 100 pieces.
