Hello everyone, I am Bokey Watch Industry. In this watch review, I will explain the Vacheron Constantin Patrimony Series 43175/000P-B190 Perpetual Calendar launched by MX Factory. The authentic version of this watch is made of 950 platinum and has an official price of 840,000. Now, let’s take a look at how well the MX Factory Patrimony 43175 Perpetual Calendar replicates the craftsmanship of the authentic model.

Review of MX Factory Vacheron Constantin Patrimony Series 43175/000P-B190 Perpetual Calendar:
First, let’s look at the front appearance. The MX factory’s Heritage 43175 uses a sapphire glass mirror, and the overall look is very transparent.

The silver-gray dial, like the original version, adopts a slightly arched design, and the color is also well-adjusted. The color will also change a little under different light angles.


In terms of details, the 12 o’clock position is the month display, which is the same as the original version with 48 small grids. The 9 o’clock position is the week display, and the 3 o’clock position is the calendar display. These three small dials are all treated with orbital patterns, and even when magnified several times, they are clear and regular.



The 6 o’clock position is the moon phase display like the original version, that is, it moves one grid a day and corresponds to the lunar calendar. And the moon phase disk is also three-dimensional. (The low-version is a printed moon phase, and the functions are also different. The sun, moon, and stars rotate with time.)

In terms of the pointer, it adopts a yin-yang pointer design, half frosted and half polished, and the central axis is also solid.

The classic brand logo of Vacheron Constantin is also a good point. It is not too thick. Including the font printing below is also in place.

In terms of size, the diameter of the MX factory’s Heritage 43175 is 41 millimeters, and the thickness is 9.5 millimeters. In terms of thickness, it will be 0.5 millimeters thicker than the genuine product. But it is also the thinnest and closest to the original version on the market now. The 0.5 millimeter difference is also not felt when worn normally, unless measured with a caliper.


In terms of weight, it will be a little lighter than the genuine product. After all, the genuine product is made of 950 platinum, while the MX factory’s Heritage 43175 is made of 316L stainless steel. Therefore, the weight cannot be the same as the genuine product and will be about 30 grams lighter. Original

The shape of the case and the buttons are all restored according to the original version, and the mirror polishing process is also in place. The four buttons also have real functions. Here is a brief explanation. The left button is the week and moon phase adjustment button, and the right is the month button, the time adjustment crown, and the calendar button. It should be noted here! When adjusting any function, first adjust the time to 9 o’clock, and then adjust it so as not to damage the movement.



The back adopts a see-through design. The middle glass is still made of sapphire material. There are also some engravings of brand information on the back cover, and the engravings are also relatively deep. In terms of the movement, the Citizen 9015 movement is used to modify the 1120QP movement. The movement quality is still relatively good. It is just that there is still some deficiency compared to the original version in appearance. But in terms of function, it is not easy to achieve the same function as the original version and it is still an ultra-thin model.


The strap is made of double-sided calfskin and has embossed crocodile leather patterns. The texture will be a bit worse. Friends with sufficient budget can customize crocodile leather with Bokey. The texture will be greatly improved.

The buckle is a double-press folding buckle. This buckle also corresponds to the needle-through method of the original version. There are also brand information engravings on the back of the buckle. Overall, the workmanship is very good.

In summary, the Vacheron Constantin Patrimony 43175 Perpetual Calendar watch introduced by MX Factory performs quite well in most aspects, except for deficiencies in material and movement appearance. If you don’t mind the above two issues, this MX Factory 43175 is still worth purchasing. It is available in several color schemes, and you can contact Bokey for specific details.
