High jewelry meets high watchmaking. Now, I know many of you aren't necessarily into jeweled watches - many of you focus more on the inner beauty of the watch - and its movement. Personally, I'm starting to see the appeal of jeweled watches - from a practical perspective, they're more scratch resistant! Let's take a look at the new Vacheron Constantin Overseas Tourbillon with a diamond bezel.

The Vacheron Constantin Overseas and even the Tourbillon is a popular watch on our forum. Many of our members have the Overseas model and some even have the Tourbillon model.
Vacheron Constantin now endows the Overseas Tourbillon model with a diamond bezel. Sixty diamonds go into this bezel!
You'll notice that the diamonds are set without any visible prongs. That's because this is an invisible setting. How does an invisible setting work? Take a look at the diagram below...

There is a metal "rail" which the diamond slides into - a groove is cut into the diamond as well to secure it to the rail. From the top, it looks like there is no setting whatsoever. But now you know how it works, underneath there is a system of tunnels with rails and grooved diamonds sliding on the rails. Now that you know the secrets to the invisible setting, you realize it's an easy concept. But in reality, it's very difficult to execute. Especially when you factor in curvature into the setting and different sized stones, and stones not of square or rectangular shape (many of the stones in this watch are trapezoidal).

So, this is where most WatchProSite readers care about - the engine room!
This is one of my favorite Vacheron Constantin calibers and one of my favorite Tourbillon calibers. Why? 1, it's got a large balance wheel diameter. This is a large Tourbillon - a larger diameter Tourbillon has more mass and therefore greater stability. 2, it's got a wonderfully traditional and slow beat of 18,000 vph. This slow beat is very pleasing to look at - some other tourbillons on the market oscillate at a faster beat, a faster beat requires a smaller wheel diameter, and the combination of smaller balance wheel diameter and faster oscillation speed can look almost violent. 3, the engineering and dimensions, the movement is thin. 4, there's 80 hours of power reserve! And 5, it's a wonderful automatic winding system with a peripheral rotor that doesn't block the transparency of the Tourbillon. What a great job Vacheron Constantin did with this movement! I would say it's one of the best Tourbillon movements on the market! The movement finishing is also wonderful. That Tourbillon cage in the Maltese cross - Vacheron Constantin's logo is done beautifully. And the Tourbillon's bridge is black polished.
Christian Selmoni, Director of Style and Heritage at Vacheron Constantin has this to say about the movement:
Calibre 2160, one of the thinnest tourbillon movements on the market at just 5.65 mm, is a genuine technical feat. For the Maison's watchmakers who developed this calibre presented in 2018, the challenge was to integrate a tourbillon regulator into an ultra-thin self-winding movement. This type of construction entails twin difficulties. The presence of an oscillating weight and the integration of a tourbillon cage generally imply additional movement thickness. It was therefore necessary to work first on the architecture of the tourbillon itself and then to design a high-efficiency peripheral rotor winding system to achieve an 80-hour power reserve. The watchmakers at Vacheron Constantin were able to respond perfectly to these constraints with ultra-thin Calibre 2160, which is also aesthetically pleasing thanks to the meticulous attention lavished on the decoration.

16 diamonds are set on the clasp. In total, 3.6 carats of diamonds are set throughout the watch! 60 diamonds on the bezel and 9 diamonds on the dial means there are 85 diamonds in total!

Watch brands are heading more towards jeweled watches. Many brands are expanding their in-house jewelry departments and some brands are buying external jewelry companies whom used to supply the watch industry with jeweled components. What are your thoughts on this trend? And what are your thoughts on this specific Vacheron Constantin Overseas with the Diamond Bezel watch?
