The ultimate balance of power

Surplus power display (power storage pointer) is a simple structure, although the invention is very great. It can not only remind the wearer in a timely manner to the chain movement, but also through effective compensation and incentive to improve torque when going down due to error. Power of authentic, objectively reflect the winding state, we found it the perfect?

The ultimate balance of power

Mechanical watches from all the functionalities have momentum (winding) output, and power protection to ensure accurate directions, otherwise they are just the same disk as vase decoration.

Clockwork's energy will weaken along with the operation of the movement, according to principles of leverage moment: when winding is on full, its maximum torque (maximum torque lever), so the front springs to lower the power output required. Running for some time, closely set in the winding axis of winding will slowly release its energy decreases. When the energy is running out, winding the end of the minimum torque (minimum torque lever), then the output power also will become smaller, and thus increase the transmission power required to maintain the movement to run. Quantitative change in the process of torque (on a full winding walking too fast down the energy walking Pianman), movement of the travel time the average Ins and Outs of accuracy entirely. With modern metallurgy techniques improved, more high-quality metal element is applied to the production of movement of the mainspring, the mainspring of the metal by changing the elasticity and resistance to fatigue, with excellent stability as far as possible the physical characteristics of the output torque. Watchmaker or polished smooth winding through the box wall in order to reduce the resistance clockwork release, or reduce the pendulum frequency, relative power in order to obtain the corresponding extension of the swatch torque range.

Even more complicated watchmaking division will carry spare parts - by Cam will "ratchet" clause box round gradually elevated from the German Stackfreed institutions, excessive winding through the gear carried on the balance cyclical loading and unloading of French constant power plant Remontoir, and Lange watch in paragraph 31, 2007 power lychipin institutions. However, these three structures failed to win the favor of all. However, sesame chain mechanism may be an exception. Whether 16,17-century pocket watch, English astronomical clock, or sailing the 20th century astronomical clock, we can see the shadow of sesame chain.

The first Sesame chain mechanism can be traced back in 1525 produced by the Jacob Zech clock. Back in 1490 Leonardo da Vinci had drawn sketches of this institution. As GH Baillie in his standard book "Watchmaker and Clockmakers of the World World Watch Production division," the book says: "Perhaps there is no mechanical problem can be so simple and perfect solution." Sesame chain system is able to release the winding output torque to overcome the inconsistency during the installation, the movement perspective, from Sesame chain link with the winding wheel like a cable box and the tower at both ends of the faithful, firmly fixed in the splint. The chain driven by the mainspring round pagoda, one end of the link chain round the bottom of the pagoda maximum radius, the other a hooked outer box springs. Cone-shaped pagoda round the outer wall has spiral grooves entrenched to the top of the tower, the chain box chain release from the primary winding volume wheel to the tower, winding on the expiration of sesame chain has Raozhi minimum radius of the apex. Clockwork maximum torque at the moment, the tower round the smallest leverage efficiency. Movement began to run, reverse the winding box will be set in the tower of sesame chain wheel drive slowly over, gradually release the power when the main winding slowly decreasing, is volume of sesame chain of transmigration from the pagoda to the process of winding box, The longer lever slowly, so that the length of the lever - that is the effective radius and sesame chain winding is inversely proportional to increased torque, the result ensures a constant torque sesame chain axis, thus ensuring a balance wheel swing constant.

"Pour le merite" Lange products is a sign of the top sophisticated equipment, are now turned into a synonym for sesame chain. Because each one can mark "Pour le merite" logo works, have strong support Sesame chain drive system.

Perhaps there are some watchmaker successfully developed a sesame-chain systems, but for now, be in addition to public recognition of inventors - Lange, the only watch handed down from father Breguet brand reached such a high achievement.

To keep the old technology as black wall hanging in a museum's statement, Lange decided to revive the traditional sesame chain. But Lange's practice to perfect it? The new "Pour le Merite" is undoubtedly the best answer to this question. This is a push to the extreme precision work, and this is the traditional craft from Lange.

Lange's followers know, this used to balance the mainspring torque transmission gear bike called pocket edition of the institutions, the Glashütte watch industry, is no longer new. When Guenter Blumlein and Walter Lange Lange in 1994 for restoration of the watch, Pour le Merite Tourbillon is the comeback of one of four works is the first time Sesame chain to a watch in miniature. This miracle should be attributed to the efforts of Renaud & Papi, and the love he think-tank advisors.

Today, the sesame-chain system has been completely transferred to the Le Locle Lange watch factory production, the move to further consolidate the Lange form can not shake the position of the top watchmaker. Clearly, Lange watch will have to wait until everything is ready, after expanding aggressively. Sesame chain linear grinding process used for decorative purposes only, grinding process of the formation of flash can also help link the bite. Small parts of each link should have its greatest effect. Richard Lange watch Sesame chain organization will be hidden in almost perfect design, the making of this idea even more mysterious (new watch with a three-enamel disk). Unlike his contemporaries, that a large window through dial tourbillon designed to highlight the rhetorical approach, Lange sesame chain is expressed in pursuit of precision, restrained, and the looming through the bottom cover. At this moment, watches are not only tools to pass the time reported, but to give time in this stage to talk to you alone.

Lange watch and Renaud & Papi in the 90's to watch when the first chain of design Chi Ma, also added three preventive measures to ensure the correct operation of institutions. First item: the mainspring fully tightened on the chain process is terminated before the leveraged institutions as a way to prevent the sesame chain crack; the second item: the improved braking power structure, aimed at winding power consumption before the complete cessation of movement operation; third: planetary gear stage to ensure the on-chain transfer of power to the movement to ensure the watch on a chain in the process of continuous power transmission.

As early as 1890 to 1945, the Lange form a total of more than 5,000 pieces produced by a marine bell sesame chain organization. Richard Lange in 1887 because of health out of business, but he remains as a consultant and submitted a number of new designs, including Sesame chain system equipped with a keyless pocket watch precision timepieces, and thus he made when the meter precision Lange title worthy of the name. Increasing prosperity in the simple style of today, people's curiosity gradually cooling tourbillon, tourbillon watches on the consumer is no longer too keen, Richard Lange Pour le Merite appearance can be described as the right time, the design of even more low-key luxury very valuable.

Do not invented just because Lange sesame chain system would only concern its work, there is an eminent watchmaker has produced a sesame chain - that is, Breguet (BRUGUET). However, the 7047 Sesame chain tourbillon watch more highlights seem to be taken away tourbillon body, after all, is the originator of this technology, as sesame chain, Breguet had only a small amount of pre-production, but handed down much. In addition, due to the blockade Breguet internal data, we can not know whether this is he sesame sesame chain chain.

Such pieces of double-tracking needle Tourbillon Chronograph, Tourbillon is accurate protection, to strive for improvement, it still Lange equipped with a constant power transmission system.
