Sihh 2019: Switching The Balance Frequency In Exchange For Ultra-long Kinetic Energy Vacheron Constantin Vatican Constantinelle Twin

Generally speaking, a perpetual calendar watch with a bracelet design has a power reserve of about three days, which is a very good level. However, VACHERON CONSTANTIN’s new work of 2019 Traditionnelle Twin Beat perpetual calendar can provide The ultra-long kinetic energy of at least 65 days greatly exceeds our imaginary limit of the perpetual calendar watch’s kinetic energy. The key factor that can promote this arrogant kinetic energy is that the brand has set up two balance wheels and two balance wheels in the same watch. The output vibration frequency is fast and slow, and it can also be switched freely. The 65-day kinetic energy mentioned here refers to when switching to a slow balance wheel, such a magical state can be achieved.

In order to solve the innate disadvantage of the kinetic energy storage of the complex watch on the bracelet, Vacheron Constantin developed the Traditionnelle Twin Beat perpetual calendar, inspired by the early ‘scheduled’ timepieces in Japan.

Vacheron Constantin did not have such an amazing idea. The brand was actually inspired by the ‘irregular’ timer used in the Edo period in Japan from the 17th to the 19th centuries. China’s twelve Earthly Timekeeping System divides day and night into six units, but each unit will be slightly adjusted due to the different seasons and the length of the day and night. Therefore, timepieces of that era often had one or two balance-wheel-like devices. It is convenient for users to freely switch the vibration frequency of the timepiece. Vacheron Constantin is from this flexible mechanism to create the Traditionnelle Twin Beat perpetual calendar. At the same time, the release of this watch also solves the market’s long-standing complex kinetic energy. It’s a disappointing defect, and it’s no wonder it makes people feel refreshed.

The dial of the watch displays perpetual calendar information such as hour, minute, date, and month, and can also detect different balance wheel modes and power reserve days in different modes.

The Traditionnelle Twin Beat perpetual calendar is made of rare platinum. Vacheron Constantin has adopted an open face design, so the machine plate on the face plate can be exposed to radial patterns and sandblasting. In simple terms, the face plate is divided into two blocks, of which gold The quality dial is decorated with hand-engraved carvings, and the outer ring is set with a sapphire crystal outer ring. The time display function of the watch is mainly divided into the lower half of the date, month and leap year display (the central axis of the faceplate is the time and minute display). As for the fan window at 9 o’clock, it represents two different vibration frequencies, reminding you to wear The user has now switched to which vibration frequency, and the concentric dial in the 12 o’clock direction of the faceplate represents the number of days of different power reserve that can be obtained by switching between different vibration frequencies.

The model uses a patent-pending mechanical system that instantly switches between active mode (5 Hz, 36,000 vibrations per hour) and standby mode (1.2 Hz, 8,640 vibrations per hour)

The wearer can switch the vibration frequency of the balance wheel by pressing the handle of the case at 8 o’clock, which is 5 Hz (36,000 times / hour) in normal state, and another so-called ‘standby mode’ 1.2 Hz (8,640 times / hour). Hours), a little unexpected is that the two balance wheels actually rely on the same barrel to provide kinetic energy. Vacheron Constantin specially developed a manual movement called 3610, which has two balance wheels in structure, but they will not It works at the same time. Only when the switch is activated, the two balance wheels can be switched with each other through the two differentials on the tooth and barrel. Because the slow balance wheel in standby mode has higher sensitivity, it The hairspring must also be redesigned. Its cross-sectional area is only 0.0774 × 0.0159mm, which is almost as small as 1/4 of another 5Hz balance spring. This also allows different frequency balance systems to coexist in harmony, even Cooperation with each other.

Driven by two main barrels, this is an efficient way to distribute energy and the only way to configure a single power reserve display

The use of 5Hz vibration frequency is mainly for the daily wearing situation. In this mode, the Traditionnelle Twin Beat perpetual calendar actually has 4 days of kinetic energy, which looks inconspicuous, but it is relatively relatively for the complex watch on the bracelet. Outstanding. However, if the watch owner does not expect to wear the watch for a period of time, it is necessary to press the button to switch to the ‘standby mode’ of 1.2Hz. Once the watch is switched to standby mode, the system will run as usual, but Because it relies on a low-speed balance wheel to operate, it can fully save up to 65 days of kinetic energy. In this way, even if the wearer does not wear the watch for a long time, there is no need to adjust the time after re-wearing. Collectors will know how convenient it is.

In standby mode, the brand’s homemade 3610 QP movement can be slowed down to ensure a minimum power reserve of 65 days.

In addition, in order to achieve the purpose of energy saving, Vacheron Constantin made improvements to the structure that used to consume a large amount of kinetic energy during the jump of the turntable display system. The date, month and leap year display of the 3610 movement are all designed for instant jump. A spring-loaded dual gear load system makes the instant jump mechanism only need 1/4 torque of the traditional jump display system, which is not only visually stunning, but also helps to extend the kinetic energy of the watch. Through the new double balance wheel switching design, the Traditionnelle Twin Beat perpetual calendar shows the infinite potential of fine watchmaking. It can also be seen that Vacheron Constantin’s efforts to create a more ideal wearing experience.
