Hola caballeros: Me he permitido repertir un post que puse anoche, por que creo que el título era demasiado "mistico". Este titulo es mas adecuado y deberia explicar en parte la enorme importancia que tiene hablar de un calibre ETA,VALJOUX ,UNITAS etc modificado por cualquiera de los grandes(o pequeños). La implicaciones tecnicas son enormes y por fin creo haber entendido realmente lo que hace Breitling, PAM etc con sus calibres modificados. Debo reconocer ante vosotros mi torpeza por no haberme dado cuenta antes de este "matiz" de tan elevada relevancia.
Me voy a permitir poneros una metafora del mundo automovilistico que tambien me entusiasma: Imaginad un motor de Seat, Renault, BMW etc ..al que le cambiamos el arbol de levas y le ponemos uno doble y de geometria variable, cambiamos las valvulas por unas mas ligeras y de mayor resistencia, pulimos las lumbreras del conducto de admision, alige ramos el cigueñal para ganar en capacidad de subir - bajar vueltas, modificamos el mapeado digital del sistema de encendido e inyeccion por otro mas avanzado, el sistema de lubricacion lo mejoramos especialmente a nivel de culata, punto crítico y para finalizar le ponemos un aceite sintetico de primerisima calidad. ¿Resultado? El motor A de serie alcanzaba 170 caballos a 5,800 rpm y su longevidad estimada podria ser de unos 250.000 kilometros, sin perdidas sensibles de potencia.
El motor B( el que hemos personalizado) rinde en banco de potencia 245 caballos a 6,900 rpm, y su longevidad estimada es de 350.000 kilometros.
A partir de aqui os edito-copio-pego lo que puse en el otro post.
Hola amigos, es tardisimo y no puedo ponerme a traducir el texto sacado de una web no oficial de Breitling. Explica muchas cosas "discretas" que no "secretas de Breitling. Posiblemente si leeis con atencion, por fin podreis entender que es lo que hace cada fabricante con las bases ETA, VALJOUX LEMANIA etc.
Os lo pongo:
Does Breitling make its own movements?
Breitling stopped making in-house movements in the early 1950s. Since then, it has used movements from a number of manufacturers such as Venus, Lemania, ETA, Valjoux and Piguet. Kelek (which is owned by Breitling) develops modules for the base movements, some of which are exclusive to Breitling.
What kind of finishing and modifications go into a Breitling watch movement?
Since Breitling's acquisition of Kelek, the level of finishing and modifications to their movements has increased dramatically. For example, a Breitling caliber 13 enhanced by Kelek tested accurate to +1 second per 24 hours (WatchTime magazine) and is nicely decorated with Geneva Waves and circular graining.
Who is Kelek?
Kelek is a Swiss watch manufacturer founded in 1896 and owned by Breitling. In addition to finishing and modifying Breitling's ETA/Valjoux/other base movements to high standards, Kelek develops in-house modules for them. You can find Kelek's official Web site at www.kelekwatches.com.
There are reports indicating that Kelek has now been fully integrated with Breitling and its new name is Chronometrie Breitling.
Who is ETA?
ETA is a Swiss movement manufacturer owned by the Swatch Group. Its history goes back to the year 1793. The vast majority of Swiss watch manufacturers buy ebauches (raw movements) from ETA. Lower-end manufacturers use the movements as-is, while better firms such as Breitling modify them to their own specifications and requirements. ETA owns the Valjoux firm.
For more information, please see ETA's official Web site.
Who is Valjoux?
Valjoux is a company whose history goes back to the late 1800s. It is well known for its early column-wheel chronograph movements such as the Valjoux 72. In more recent history, the Valjoux 7750 has been used by a great variety of watch manufacturers including Breitling. Another common Valjoux movement is the 7751 which, in addition to the 7750's time/date/chronograph functions, has day and month indicators, a 24-hour indicator and a moon phase indicator. Valjoux is owned by ETA.
What is a 2824?
The 2824 is a mechanical self-winding (automatic) time/date movement made by ETA. It is a very rugged and reliable movement used by many manufacturers. In Breitling form, this movement is accurate enough to pass COSC certification tests. This movement is the base for Breitling caliber 17 used by the SuperOcean and other models.
What is a 2892?
The 2892 is a mechanical self-winding (automatic) time/date movement made by ETA. It is a reliable and fairly thin movement considered more refined than the 2824 workhorse. This movement is known for its great accuracy and is used by many different manufacturers. It can be fitted with a chronograph module.
What is a 7750?
The 7750 is a mechanical self-winding (automatic) time/date/chronograph movement made by Valjoux. It is a rugged, reliable, accurate and thick chronograph movement. Breitling caliber 13 is based on this movement and has proven very impressive in accuracy tests at an average of +1 second per 24 hours. Caliber 13 is used in many Chronomat and Navitimer models as well as in the Avenger.
Por fin alguien es claro dando los matices que explican muchas cosas, por lo menos para mi. Y con absoluta seguridad este nivel de modificaion e implicacion tecnologica es aplicable a muchas marcas que amo especialmente, como Omega, Panerai, Sinn etc etc
Seguro que alguno de los miembros profesionales del foro nos puede matizar y profundizar mas aun en el tema, pero para mi esta zanjado. Por fin un poco de iluminacion en medio de tanata oscuridad.
Un abrazo y buenas noches.
Un abrazo.
