Hola,
no mirado que dicen en la web ni que dice la casa WARD. Lo preguntado en Suiza a gente que lo saben.
No entendido nada mal y no lo sabia, que la misma casa se refiere CON SU CALIBRE al 7750 como un tractor basico sin decir que EL 7750 ES LA BASE .
Claro que no dicen que el Valjoux 7750 es la base por que son unos listos, y creo que pueden decirlo, Panerei tambien lo dicho.
Saludos
O igual es que no lo dicen porque quizá no sea la base y efectivamente sea un calibre diseñado de cero. Y, sinceramente, pareciéndose uno a otro como un huevo a una castaña, me da que, o no lo será, o está aún más modificado que un Destriero Scafusia.
Hay otro motivo por el cual les daría credibilidad. Para algunas firmas el tener un calibre propio supone nada más que poner un sello a un rotor. Éstos tienen varios calibres modificados (fechadores más grandes, horas del mundo, monopulsante, horas saltantes) y los habían vendido como tal sin ocultar los calibres base, esto es, ninguno antes los habían vendido como manufactura.

Horas del mundo.

Bespoke ETA 2824-2 Jumping Hour automatic modification by Johannes Jahnke
Así como en las descripciones (un tanto pomposas)...
However, for those of us to whom the true art of a watch lies beneath the dial, it is the work that our Master watchmaker Johannes Jahnke has done with the ETA 2893 automatic movement that makes this such a beautiful watch. To make both time-zones function on a 24 hour basis unlike the usual variant of one at 12 hours and only the GMT hand rotating once every 24 hours, Johannes has modified the gearing of the 2893. Additionally, he has managed to add this to a rotating disc which, in this variant of the C900, has the time-zones indicated by individual airport codes in a window at 12 O'clock. The same disc indicates the geographic location on the C900's magnificent 3-dimensional world map dial.
The modifications, all managed through the single crown function, render the C900 Worldtimer incredibly easy to read and operate – something that every world traveller will appreciate.
We believe Calibre JJ03 is a world first for Christopher Ward, no small feat in itself, and a patent has been applied for which is currently pending.
The Mark I version of our Jumping Hour watch was a finalist in the 00/24 Watch World European Watch of The Year Awards 2012 and the extraordinary JJ01 complication, created by Master Watchmaker Johannes Jahnke, has deservedly been acclaimed by many experts since its arrival in 2011.
For the Mark II version and this special solid Rose Gold Bezel edition, Johannes has further refined his ingenious adaptation of ETA's 2824-2 movement to produce what, in his own words, is probably the most precise jumping hour movement the world has yet seen, and a true collectors piece. Hyperbole is anathema to Mr Jahnke so you can ignore his "probably" probably! Witnessing the remarkably smooth transition of the hours and the perfect alignment of minute hand and hour dial is a delight and glorious affirmation of devotion to continuous improvement.
At the time, Jahnke told me of his latest project - the creation of another monopusher chronograph based on a highly modified Unitas movement. More than six months later, this has come to fruition in the form of Christopher Ward's most sophisticated and complex watch to date, the C900 SP - a beautifully understated, classic-looking chronograph powered by its own, exclusive, monopusher movement.
It is partly for that reason that this new movement has taken almost three years to develop following Jahnke's discovery of a prototype chronograph in 2009 which was based on the well known Unitas 6497 calibre. Jahnke was immediately taken with the thinking behind the mechanism, recognising similarities with the single pusher movement he had developed at Lang & Heyne for the aforementioned King Albert single pusher chronograph. What really excited him about the Unitas project, however, was his belief that it could be extensively improved both mechanically and aesthetically in order to create a superbly clean and functional wristwatch - and one which would also offer instant appeal to horophiles due to the fact that the mechanics of the movement could be clearly seen and understood. Jahnke did not, however, want to realise this new mechanism entirely alone and it is for that reason that he sought the collaboration of Fillon, whose knowledge of creating and manufacturing parts for chronograph movements had become the stuff of legend. The prospect of working with such an industry veteran could have been daunting for Jahnke, who is Fillon's junior by more than half a century, but the old hand instantly recognised the abilities and talent of the younger man who quickly came to affectionately refer to his mentor as 'opi' or 'grandpa'.
Working together, the pair deconstructed the Unitas base and effectively re-designed its chronograph function with hand-drawn, annotated sketches that enabled Jahnke to then reconstruct the module using a CAD programme. The result was an extensively reworked movement with a new main plate, bridges, winding mechanism, centre and second wheels.
