Corum Corum Black Ceramic Gold Bridge Watch

Corum Corum’s famous Golden Bridge watch, which combines straight-line transparent art, introduces the black ceramic style for the first time, making its superior and unique structure a more detailed interpretation. The case is made of ceramics, one of the strongest materials. It is made up of a long movement with a complex structure, which shows the subtle chemical effect between the improvement of technology and pure art.

Molding an all-ceramic case requires injecting crystals into the mold at about 980 times the atmospheric pressure, which is a very difficult process. The first challenge in the production process was to ensure that the material was evenly distributed to avoid rough and uneven surfaces, and then placed in an oven and fired at 160 ° C for 30 seconds, making the material with many fine pores still harder. After this process, the ceramic volume will shrink by about one-third to reach the target of 34 × 51 mm size. To do this accurately, you need to fully grasp the firing time, because deviations of a few seconds may cause excessive shrinkage, so that the case is too small to accommodate the movement.
The ceramic Golden Bridge watch injects light aesthetics into the highly precise watch craftsmanship, and the elongated lines of the long movement extend into the elegant barrel-shaped case. This special mechanical structure was first created in 1980, and instantly became a symbol of the Swiss watch industry. Its unique linear structure cleverly meets the requirements of kinetic energy transmission and is definitely a masterpiece in the watch industry. This perfect pure ceramic Golden Bridge watch also sets the crown at 6 o’clock, as if letting its CO 113 manual winding movement stretch out. The watch’s sliding mainspring winding system can avoid affecting the movement due to excessive winding, and the gears and pinions are installed between the main board and the bridge. This clever structure allows the special clutch to adjust the winding and time. More separated. Abandoning the classic scale indication or three-pin one-line design, the watch movement is equipped with a variable inertia balance, which can ensure that the watch remains accurate for a long time. The movement has a vibration frequency of 4 Hz (28,800 vibrations per hour), a power reserve of 40 hours, and two bridges on the bridge to strengthen and strengthen the watch, making it more accurate.

The long movement is placed in a black ceramic case, and the surface, back and sides are made of sapphire crystal glass. 360-degree perspective of the linear movement structure makes people immersed in the charming transparent art. The splint bridge on the upper level is made of 5N 18K red gold and is decorated with a hand-carved Corum logo. It is surrounded by elongated scroll patterns that depict three types of places where the Golden Bridge watch was born. Ferns in the forest of La Chaux-de-Fonds, Switzerland, are exquisitely handcrafted; the main board made of red gold is also embellished with delicate hand carvings, showing the finest traditional watchmaking techniques. The hollow rod-shaped hands on the movement reveal the watch’s design without surface, which makes the transparency more prominent. The elegant alligator leather strap with black PVD coating pin buckle adds a part to the watch. Elegance.
The Golden Bridge watch, made of ceramics, embodies a light weight, exquisite and clear aesthetics, and presents a fascinating spectacle.
