The upper chord is to transfer energy to the original moving system, and the pulling needle is the mechanism for cocking the pointer. This mechanism includes not only the movement of the hour and minute hands, but also the display parts of the additional mechanism carried by the drive core, such as the calendar and the weekly calendar. By the crown, the stem, the vertical wheel, the clutch wheel, the clutch lever, the clutch lever spring, the pull gear, the compression spring, the setting wheel, the span wheel, the hour wheel, the minute wheel, the large steel wheel, the small steel wheel, the pawl, Pawl spring and other components. The automatic winding is composed of a heavy hammer, a heavy hammer support, an eccentric shaft, a ball, an automatic rocking plate, a ratchet, a pawl, and an automatic upper plate.

As one of the few accessories for men, the watch shows the mature qualities, refined style and vitality of men.

In addition, in order to prevent interpretation errors, the device must also be provided with a design that prevents inadvertent inadvertent rotation. It is best to assemble a timed rotating inner ring for diving with a detailed minute scale. The device that controls the rotating inner ring should also have a corresponding safe start design. The time, the rotation of the inner circle, the movement of the movement, etc., must only be clear in the dark and deep sea environment. greubel forsey art piece edition historique


Usually this distance (the straight distance between the watch and the eyes) is set to 25 cm. Among them, fluorescence processing is the most commonly used solution for major watch manufacturers. In order to ensure that the core components and straps of the watch do not change under the salt water immersion environment, the waterproof gasket, bottom cover and mirror surface of the diving watch should be adjusted accordingly. The common practice is to increase the thickness. The NIHS standard stipulates that the watch case of a diving watch should have a waterproof depth of more than 100 meters.The second problem with the evolution of watches is the way the escapement is. The pendulum is still too large, and it is greatly affected by the ground and cannot be tilted, so it cannot be carried. He replaced the original pendulum with a gossamer. This formed a small clock that was powered by a spring and used a hairspring as a speed governing mechanism. It also provided conditions for making a bag that was easy to carry. . In the 18th century, various escapement mechanisms were invented.

In 1726, Gallo perfected the escapement of the I-shaped wheel. By the 19th century, pocket watches had become widely popular. The difference between the mechanical watches and the 19th century is not. Big.Professional diving watches are equipped with anti-magnetic protection, because the extremely sensitive balance spring is likely to destroy its accuracy due to the influence of the magnetic field. The anti-magnetic protection device protects the movement from magnetic fields, vibrations and temperature changes, ensuring accurate timekeeping. In addition, the temperature change test of the watch is required, and no steam condensation phenomenon is found to be a good diving watch.
