Hollow the watch may look very cool, seems to be to meet the new trend of the times a different approach. No, it has actually appeared in the world of human watchmaking long ago. It is said that in 1760, several well-known brands are not yet come out of the era, the French watchmaker André-Charles Caron created the first pocket cheap replica watches with a hollow structure; he believes, so that people can see the timing How does it work?

However, if you flip the watch, you will find that the movement has a complete balance before and after the balance spring, balance spring and fixed balance bridge, the so-called “double balance wheel” structure. When the power from the spring is transmitted to the escapement, the two coaxial balance wheels operate in the same direction at the same time, while the balance springs are zoomed in the opposite direction to compensate for the difference in orientation, so that they are like the tourbillons. Eliminate the impact caused by gravity, improve travel time about 30% accuracy. Balance, the 3132 automatic movement of the hollow parts is also impressive. Every chamfer and its mirror finish seen by the viewer must be completed and assembled by manpower one by one, which is not easy. And this is also the most appreciated from the appearance of the place.

But it is also a time-mark, and it is a roman numeral hour-marker full of classical flavors. On the movement bridge, it is both very structurally meaningful and has the function of meeting the needs of reading. It is a very clever way.


Driving watch is 9621 MC-type automatic movement; Although the automatic winding, hollow surface but did not see the automatic disk traces until it turned to the table back and it was also adopted hollow design, no wonder can be hidden perfectly!

Vacheron Constantin
Vacheron Constantin in the 1920s began to create Lou engraved movement, not the earliest, but it is a major brand continues today. The difference from the structure of the movement, which is removed directly from the face plate, lies in the hollowing out of a large part of the material and the carving of motifs on the remaining parts. This is, of course, a very labor-intensive practice, but the process demonstrated is rather delicate, beautiful and speechless.


Openwork is a process of eliminating excess. Vacheron Constantin through craftsmanship exquisite craft, the hollow movement to be perfect.
Lou pattern depends on the brand wants to convey the concept of this Métiers d’Art Lou mechanical watch, for example, is the late 19th century train station hall vault ornaments, station essential large The clock and its Roman numerals are fully reproduced. 18K white gold case equipped with 4400 SQ manual winding movement is actually Vacheron Constantin acclaimed 4400 movement carved, the result of modification.

It can be quickly and massively manufactured, and includes a 12 o’clock direction to decorate the barrel Of the Maltese cross, and the triangular pattern of bevelled above. Chamfer often used in movement modification also appears in the details of the office, mining mirror polishing its lines and matte polished staggered parts, contrast.

Thanks to the 2.8mm thick movement, the watch is presented in a slim 7.5mm size. It is precisely because of limited space, more admirable for such a delicate, flawless creation.
