The horological company Jaquet Droz has manufactured a unique watch to be introduced at the Only Watch 2009 charity auction.
This exceptional model exposes a white ceramic case with a diameter equal to 44mm and a red enamel dial. The latter reveals off-centered hours and minutes as well as a large seconds counter.
It is interesting to note that the right color of the ivory enamel dial is attainable by means of applying about 10 layers. Each of them should be fired at 800°. For you to compare, black color requires 15 layers and 15 firings, blue color needs 18 or 19, while the red color can be achieved with 22 layers. Each layer coated presents a new complication and every time it is exposed to firing there appears a risk of both breakage and bubbling.
According to Jaquet Droz CEO, Manuel Emch, it took the company six years of dedicated work to finally stabilize the red color. This completely red dial has been fabricated by Jaquet Droz for the first and, perhaps, the last time. The reason for that is an uncommon reaction of the red color to the firing, which results in a lot of breakage.
The exceptional Jaquet Droz Only Watch 09, the grande seconde ceramique, hommage Geneve 1784, Ref J003036207, is animated by an in-house 2663 caliber automatic mechanical movement, set with 30 jewels. The movement features a balance wheel moving back and forth at 28,800 vibrations per hour and offers a lengthy 68-hour power reserve, ensured by double barrels.
The Jaquet Droz watch boasts 30-meter water-resistance. This model is accompanied by a natural white rubber strap finished with a stainless steel folding clasp.
