High-end watch maker Vacheron Constantin’s Watches & Wonders Geneva 2021 news continues. Previously, I introduced the Historiques American 1921, which celebrated its 100th anniversary this year, in detail (>> Link to related Time Forum report). This time, some of the new models from the Les Cabinotiers collection, consisting of one-of-a-kind one-of-a-kind timepieces, gathered together with the Maison’s know-how in fine watchmaking. gathered in one place.

Cabinotier Amilary Tourbillon Perpetual Calendar, aka Planetaria, is a double-axis tourbillon and perpetual calendar (retrograde date/day/month), northern/south moon phases and day/night It is a model with a grand complication specification that is huge at a glance even with an indicator. This is the latest update to the wristwatch version, which puts the Maison’s time-honored calendar and astronomical know-how into one movement. As replica Vacheron Constantin named this year’s theme ‘Le Temps Celeste’, it is expected to focus on the Maison’s long-term astronomical complications through a series of timepieces.
Celebrating its 260th anniversary in 2015, the Ref. As Vacheron Constantin introduced the 57260, it is not difficult to present the type of astronomical clock you want if you really want to. Cabinotier Amilary Tourbillon Perpetual Calendar – Planetaria is a symbolic model that opens this year’s ‘celestial time’ theme, and Vacheron presents the reason for the existence of mechanical astronomical clocks and new possibilities for modern people living in the 21st century. It can be said to be a constantine-style answer.
The Cabinotier Amilary Tourbillon Perpetual Calendar in Pink Gold – Planetaria has a case diameter of 46 mm and a thickness of 20.20 mm, which makes the fake watches stand out from the outside. It is an unavoidable part because it brings together so many different complications. A completely new caliber has, of course, been developed and equipped for new types of complication combinations.
The first thing that catches the eye of the in-house manual caliber 1991, completed after about four years of research and development, is the large-diameter, three-dimensional tourbillon cage exposed under the bubble-shaped sapphire crystal on the left side of the openwork dial. The Maison refers to this as the Armillary Tourbillon. It is said to be named after the celestial sphere-shaped observation device (Amilary) invented by Antide Janvier, a French watchmaker active at the end of the 18th century. The Amilary Tourbillon is the iconic model Ref. The 57260 was first introduced in the form of a wristwatch through the Maître Cabinotier Retrograde Armillary Tourbillon released in 2016 the following year. Come to think of it, Cabinotier Amilary Tourbillon Perpetual Calendar – Planetaria shares many similarities with its predecessor, Matre Cabinotier Retrograde Amilary Tourbillon, in terms of unique layout and functionality. This is a passage that can sufficiently infer what caliber the new caliber 1991 is based on.
As it is based on the 1990 caliber of the previous Matr Cabinotier retrograde army tourbillon, the design of the signature military tourbillon remains intact. The double-axis tourbillon cage, which rotates once per minute along two axes, is made of ultra-light aluminum alloy, and the escape wheels and levers that transmit power to the balance vibrating at 18,000 beats per hour (2.5 Hz) are diamond-coated ( The tip of the pallet fork uses real diamonds instead of artificial rubies!) It actively percussions the problems of continuous friction and lubrication to ensure isochronousness.
Also, if you look closely, you can see that the shape of the balance spring is unusual. I used a spherical and thick balance spring applied to marine chronometers in the past, and the combination of a multi-axis tourbillon and a spherical balance spring is very similar to that of Jaeger-LeCoultre’s Hybrid Mechanica series belonging to the same group. It must have been that there was no technical exchange?!
