Et merke jeg er lite kjent med. Sett etpar modeller som er interessante men utover det lite kjennskap. Noen som vil øse av sin kunnskap eller sine fordommer mot GP, ja utover en link til hjemmesiden deres
Ser du sett på Mogens Sea Hawk
Har sett mye morsomt vintage fra GP.
Dukker stadig vekk opp på min eBay-turer,
har ikke helt kommet up-to-speed på hva de har i katalogen om dagen men jeg har absolutt godfølelse for dem som brand/manufaktur(?)
Helt enig med Mogens, 1966 fra GP er noe av det fineste man har sett de siste årene :
og chronographen er en av de peneste auto-chrono som finnes :
Girard Perregaux ( dessverre ? ) har lenge vært langt flinkere til å lage ur enn til å markedsføre dem.
Veldig stilig både denne og chronoen (hvit skive + blånerte visere på chrono er vel velkjent MM23? )Helt enig med Mogens, 1966 fra GP er noe av det fineste man har sett de siste årene :
perpetual calender-en er et syn :
Mulig det er en uheldig vinkel, men dag-dato ser veldig flytende ut. Dag-dato på en hederlig Seiko (unnskyld lignelsen) hopper jo over "digitalt" ved midnatt. Er disse girede om fra timeviseren så du på natt mellom lørdag og søndag står mitt emellom Sat/Sun
Ingen dressmann men denne er råflott. Jeg har tidligere lagt min elsk på denne Laureatoen i titan, et syn for guder.GP-s Tourbillon sous 3 Ponts d'Or er et ikon i Haute Horlogerie segmentet :

Jeebus, dette var saker! Hmm, dette må sjekkes ut nærmere
THE GREAT ESCAPEMENT
Girard-Perregaux’s Constant Escapement marks a breakthrough in watchmaking technology.
Words by Kelvin Tan
The back of Girard Perregaux Constant Escapement back.
At Baselworld 2013, easily one of the biggest stories was the announcement of the Constant Escapement from maison Girard-Perregaux. Before we begin to expound the virtues of the Girard-Perregaux Constant Escapement LM, let
us first understand a little about the escapement of the mechanical watch.
Girard-Perregaux Constant Escapement close up.
The part of a mechanical watch called the escapement is the device employed by watchmakers to transfer mechanical spring energy to the timekeeping element of the watch, the balance wheel. A coiled spring is normally wound either by the crown of a watch or by the moving weight in automatic watches called the rotor.
When wound, this spring holds potential energy that needs to be released and changed into kinetic energy as the spring uncoils and the barrel that contains the spring rotates. The energy is then transferred, via gears attached to the barrels, to the balance wheel in order for the balance wheel to oscillate and allow the watch to keep time. It is the escapement of the watch that prevents the spring from uncoiling unchecked and releasing all of its potential energy in an instant. The escapement does this by the use of a locking action on the tooth of an attached gear, subsequently releasing this lock to drive the gear forward. As soon as the escapement reaches the next tooth, the locking action happens again and the cycle repeats until all the potential energy stored in the spring is dissipated. This repetitive cycle of locking and advancement to the next gear tooth occurs at a somewhat constant rate — thereby allowing for accurate timekeeping. The locking and driving motions are what cause the “tic- king” sound of the watch, and expend most of the potential energy of the coiled spring into both kinetic and sound energy.
Sketches of Girard-Perregaux movement.
We’ve mentioned that the release of the energy from the spring in a mechanical watch is only somewhat constant. One of the traditional escapement system’s key weaknesses is the problem of the loss of amplitude. To explain, a coiled spring does not release its stored energy at a constant rate—there is a tendency for the feed of this force to diminish as the spring becomes less and less tensed. It is due to this inconsistency that there is a variance of timing in the rate of oscillation in the lock and release motion of the escapement. The inconsistency is a problem that has plagued mechanical watches since their beginning and, of course, watchmakers have been looking for a solution to resolve the timing errors stemming from this lack of stability.
The GirardPerregaux Constant Escapement isolate.
In 2008, the late President and Chairman of the Sowind Group, Luigi Macaluso, stepped up to the challenge and began promoting the idea of a watch that contains an es- capement capable of providing a constant feeding force to oscillate the balance wheel of the watch. After five years of research, a solution was found and we are now able to marvel at the Girard-Perregaux Constant Escapement LM. Let us now try to grasp at how this watch tackles the problem. With the “constant escapement”, the skilled watchmakers at Girard-Perregaux provide a complex but elegant solu- tion in the form of a mechanism that is placed within the escapement of the watch. This incredibly thin mechanism is a spring-like 14mcr silicon blade several times thinner than a human hair that stores energy up to a certain threshold before releasing it instantaneously upon crossing that threshold.
The original idea for this blade came from a Rolex watchmaker, Nicholas Dehon, who was playing with his train
ticket while waiting for his ride. He saw that if he bent the ticket between his fingers, the card would bend slowly into the form of the letter “C”. Subsequently, when he continued to push inwards but with a slightly opposing force, the card would snap into a mirrored form of “C”. At that time, however, the use of silicon in watches was not as prevalent, and the idea had to be put aside until technology allowed it.
It was Stéphane Oes who finally realised the dream by incorporating silicon into the equation (as Nicholas Dehon had by then left Girard-Perregaux).
Simply put, through an evolution of ideas, the silicon blade is able to cause the balance wheel to drive forward by matching and complementing the dissipating energ y from the spring in the barrel of the watch. The heartbeat-like pulsating motion of the blade acts as a “guide” to ensure that power from the spring as well as the blade itself pumps into the escapement with greater stability and consistency. To fully realise this concept, twin and opposing blades are placed on the escapement itself. Two escapement wheels are then employed, with teeth cut into them to ensure that they oscillate at a stable 3 hz (21,600bps). Similarly, to take advantage of and to power the system, twin barrels with two springs totalling 3m in length are employed; coupled in parallel. Due to these parts working in sync and at an efficient rate, the power reserve of the watch is effectively increased to one week. As a bonus, the in-house GP calibre MVT-009100-0007 that contains the constant escapement has an aesthetically pleasing appeal not found in any other watches before this.
The GirardPerregaux Constant Escapement LM
Certainly it is Girard-Perregaux’s prerogative to show off this new movement in a watchcase fitted with transparent sapphire front and back. And we feel it is only right that Girard-Perregaux enhances the visual feast with the skeletal design approach and a truly fine finish. On the watch, we see a relatively large 48mm 18k white gold watch case and matching dial with a symmetrical design. This design incorporates traditional as well as contemporary elements, with the t wo large spring barrels centralising the hours and minutes register coupled with a linear power reserve display just at the center. The entire bottom hemisphere of the dial is then reserved for the Constant Escapement, which highlights the aforementioned sinusoidal blade, all bright and blue, working in sync with the new escapement. One will also not miss the classic and iconic three bridges of the maison sharing the limelight with this beautiful display of watchmaking prowess.
GirardPerregaux constant escapement movement assembled.
At the end of the day, with the watch as a symbol of man’s ability to find solutions to cross the barriers of engineering in the realm of mechanical watches, it is only fitting that it be named as a nod to Constant Girard (who, along with his wife Marie Perregaux, founded Girard-Perragaux) and Luigi Macaluso. This revolutionary piece from the maison is representative of Girard-Perregaux’s status as a true vi- sionary in the Swiss watch industry. Moving forward, the watch will serve as an example and a way forward for what is promised to be seen in the future models of Girard-Pe- rregaux’s lineup of Haute Horlogerie. For now, we can only dream of being one of the lucky 10 owners of the initial
iteration of this truly amazing timepiece.
