Create a full ceramic case, is a real subtle movement, involving about 980 bar pressure is injected into the mold crystal. The first challenge involves ensuring that the material is uniformly spread in order to avoid any of the obtained roughness of the surface texture. The next step is a 30 seconds in an oven heated to 160 ℃, porous material to harden still firing.
This will lead to a very tricky phase ceramics about a third of the volume shrinkage, to reach its final 34 × 51 mm in size. Arduous task that requires time to fully grasp the firing, because a few seconds too excessive contraction may bring the case to the caliber too small to accommodate.
Ceramic Jinqiao instill air is a high precision light aesthetic achievement. Slender silhouette, eye-catching and elegant rectangular tonneau movement extends along the length of the case. This mechanism is first created in 1980, quickly established itself as the icon of the Swiss watch industry to meet its extraordinary ingenious vertical axis implied by building energy transmission challenges. Impeccable pure ceramic Jinqiao even lined up at 6 o'clock position of the crown, as if to form an extension of their hand injury CO 113 movement.
Skid systems avoid forcing the spring winding mechanism, and a specific coupling clutch has been developed to separate the winding wheel and a clever pinions are mounted between the main plate and the architecture of the bridge, wherein the setting from the time. Caliber than the classical index, or modulating system, but with variable inertia balance, to ensure excellent long-term accuracy. Beat frequency of 4 Hz, with a 40-hour power reserve, showing the two pillars of the bridge and protect and enhance the rigidity - and thus more accurate motor function.
Combines excellent linearity and transparency, the legendary Golden Bridge appeared in a black ceramic version offers an extremely complicated explanations, and its unique architecture. Bread exercise heightened complexity of the case material to shape one of the toughest, which reflects a subtle refinement of chemical reaction between the technical and aesthetic purity.
