Last year Jacob & Co. replica presented a very interesting watch with an extravagant movement, which they called the Astronomia Tourbillon. In 2015 Jacob & Co. The Astronomia Tourbillon returns with a new case design in a version that is completely in the style of the brand and inlaid with more diamonds, called Jacob & Co. Astronomia Tourbillon Baguette.
In last year’s model, most of the movement is on levers that rotate the entire dial every 20 minutes. These levers also move to provide other functions such as time display and tourbillon operation. Looking at the entire gear ballet at Jacob & Co. Astronomia Tourbillon, then doubts arise – can this really be? Whatever their attitude to what Jacob & Co. produces, they have to give it their due – they recognize the need and importance of an element of entertainment in the luxury watch industry.
Compared to the large sapphire dome in the original Astronomia, the new case on the 2015 model has been slightly reimagined. There are smaller sapphire crystal areas (which are now split into a row of windows and one large one at the top) with the added addition of metal to create a more palatable and more wearable design. Jacob & Co. Astronomia Tourbillon have a case size of 50 x 25 mm. The case is made of 18k rose gold, there is a version with and without diamonds.
There is no crown and buttons around the perimeter of the case. In fact, the movement is set and wound up by means of two bow-shaped folding levers on the back of the case. The movement, which is, of course, the most interesting element in Jacob & Co. The Astronomia Tourbillon is an exclusive JCEM01 Caliber with a 48-hour power reserve and a tourbillon that runs at 2.5 Hz. Surprisingly, the mechanism consists of only 235 parts that seem to work with great efficiency given the complexity of the concept.
Technically speaking, due to the fact that the tourbillon moves around the entire dial every 20 minutes, it can be called a triple-axis tourbillon. The other axis is the normal centrifugal axis, which can be seen from the tourbillon stand, and which also unwinds in the connecting arm. It is located opposite the time dial to balance the weight. The other two levers are equipped with a prototype hand-engraved titanium globe, while its opposite arm has a rotating diamond ball that makes a full revolution every 60 seconds.
Jacob & Co. claim that the spherical diamond uses an exclusive cutting technique that was developed by the brand itself to create a diamond with 288 facets. This rounded diamond is designed to represent the moon. Despite the fact that the Jacob & Co. The Astronomia Tourbillon looks like it had astronomical complications in it – it really is just a concept. The mechanism was designed with aesthetic pleasure in mind, not strict functionality – and in that it excels.
Jacob & Co. The Astronomia Tourbillon Baguette depicts the night / space sky on its dial with baguette-cut diamonds. The dial and lugs are encrusted with diamonds. The total number of stones is 342, with a total weight of 16 carats.
