But what makes the Jacob & Co. Astronomia Dragon Tourbillon even more special is the gravitational tourbillon cage rotating on three axes. While the first axis makes a rotation every sixty seconds, the second axis will make a rotation every five minutes and the third axis will make a full rotation every 20 minutes. jacob and co astronomia dragon price
Below, you can see a video from last year of the Jacob & Co. Astronomia Tourbillon in action. Much of the movement is placed on a series of four arms that rotate around the entire dial each 20 minutes. Those arms also move to create other actions such as keeping the dial to indicate the time in the proper orientation, as well as operating the tourbillon. Taken together, the entire ballet of gear work in the Jacob & Co. Astronomia Tourbillon is almost hard to believe. More so, as much as you may like or be ambivalent to what Jacob & Co. produces, you have to give it to them that they understand showmanship is an important part of the luxury watch industry. jacob and co astronomia replica
Compared to the large sapphire crystal bubble dome over the initial Astronomia design, this new 2015 case makes a bit more sense. We are still looking at computer renders, but I am confident that the smaller pieces of sapphire crystal (which are now divided into a series of windows and one large one over the top) with the additional metal makes for a more plausible, wearable design. According to the brand, the Jacob & Co. Astronomia Tourbillon is 50mm wide and 25mm thick. The case is in 18k rose gold, and there is a version with and without diamonds.
Notice the lack of crowns or pushers on the case? The movement is actually set and would via two “bow-style” fold out crowns on the rear of the case. The movement, which is, of course, the most interesting element of the Jacob & Co. Astronomia Tourbillon, is the exclusive to Jacob & Co. caliber JCEM01, with 48 hours of power reserve and a tourbillon that operates at 2.5Hz. Surprisingly, the movement is produced from just 235 parts – which seems very efficient given the complexity of the concept. jacob & co astronomia replica
