The most beautiful movement with two colors｜MB&F HM9 Sapphire Vision

Launched in 2018, the Horological Machine N°9, also known as HM9, is one of the most eye-catching and representative fashion replica watches of MB&F. Its unique avant-garde appearance is derived from the design of cars and airplanes in the 1940s and 1950s. It is full of domineering . In addition to the eye-catching exterior design, its internal mechanical structure was described by the brand founder Maximilian Büsser as "the most beautiful self-made movement so far". Therefore, there is a HM9 Sapphire Vision version with a transparent sapphire crystal case, which allows people to see Internal precision structure. Now the transparent version adds two more styles, one with an 18K gold frame and a PVD green movement, and the other with an 18K white gold frame and a PVD blue movement, each limited to 5 pieces.

The first-generation HM9 Flow watch covered the balance wheels with sapphire crystal domes, and placed a magnifying glass above the planetary differential gear, allowing people to glimpse this complex mechanism that controls the timing function. The HM9 Sapphire Vision fully discloses the mystery of the movement, allowing people to clearly see the cooperation between the mainspring drum and the balance wheel, or the differential gear and the dial. high quality watches replica

This series initially launched a total of four styles, and now two new members have been added. The overall design is the same as the previous generation, and the color matching has been changed to a color combination of gold with green, or platinum with blue. The case is composed of sapphire crystal mirror and precious metal, showing a bubble-like curved sapphire crystal mirror case is divided into three parts, a total of five mirrors are assembled precisely, and then joined with high-tech composite materials with patented 3D gaskets The exclusive technology is tightly sealed to ensure complete waterproofing, and the seams with the outer frame are almost invisible.

The new HM9-SV also continues the existing mechanical structure. In order to match the design of the buy replica watches like a spaceship, it retains two independent balance wheels equipped with planetary differential gears. There is a coaxial propeller below each. The rotating turbine greatly enhances the visual effect of the watch, creating the feeling of looking into the cabin from a spaceship.

Two independently oscillating cantilevered balance wheels transmit the timing information to a differential gear, allowing the respective frequencies to be integrated into one. The extremely precise bevel gear rotates and transmits the kinetic energy and data of the movement through 90 degrees to drive the time display on the dial.

As the center of gravity of the watch, the HM9 manual winding movement equipped in the best cheap watches is quite interesting. For a modern watch, it may be a bit out of date to operate at the traditional 2.5Hz vibration frequency, but the watch makes up for the sensitivity of the lower vibration frequency to vibration through the innovative mechanism of the double balance wheel. In order to further reduce the sensitivity to vibration, the watch has added a new shock absorber system, that is, a coil spring between the movement and the case. Laser cut from a single solid tube of polished stainless steel, these springs provide excellent elasticity with minimal lateral movement.

It is also worth mentioning that the twin balance wheels are extremely difficult to adjust, and the standard practice in adjusting replica luxury Watches balances is to measure the rate of oscillation by the beating sound of a single balance wheel. However, the HM9 movement equipped with a double balance wheel device will emit two sets of sounds at the same time, so this method is not applicable. Therefore, since its launch in 2018, each Horological Machine N°9 watch has been adjusted by first separating the balance wheel on one side, adjusting the other side, and then swapping.
