Three questions about the timing of Jacob’s astronomy master
Architecture, imaginative watchmaking.
Jacob & Co. is known for making jewellery (real “Bling”), which is popular in entertainment and sports. Although the New York jeweler’s watch is not suitable for the faint-hearted, technically and conceptually, the complexity is very interesting. It is rare in modern watchmaking. In this case, the top design also has the same innovative movement. .
At this year’s Basel International Watch and Jewellery Show, luxury Jacob & Co. added long Uber complications to one-minute rather than two-minute repeaters. The first is the appropriately named Twin Turbo Furious, which is a decimal repeater with a pair of three-axis tourbillons (a watch can form six axes) and a single-button chronograph, and the second is Astronomia Maestro. Both watches are visually stunning and impressive, but the astronomical drama is completely different.
Maestro is the latest model in the Astronomia series and has become the symbol of Jacob & Co. Oversized watches have a variety of orbital complexities under the panoramic sapphire crystal. Astronomia’s latest appearance is a three-axis orbital tourbillon and a carillon minute repeater.
It was conceived by the watchmaker Luca Soprana and his complex workshop Ateliers 7h38 (by the agency responsible for the development and assembly of all Jacob&Co.’s gorgeous complexity). It took two years. The astronomer’s diameter is 50 mm. 26 mm thick. It is huge, but it should be the size it deserves. The watch looks good.
The case is rose gold, with a sapphire glass window on the strap, which offers a wide view of the movement and striking device. It is worth seeing.
The basic premise of this watch is the same as other astronomical watches: the center of the movement is a four-arm support system, which completes a rotation in 10 minutes, with various complications on each arm.
But among the masters, the combination of complexity has changed. The dial that displays the hours and minutes is located above the central axis, rather than its typical position on one arm, providing a more intuitive time reading. There is a moon phase disc on one arm, which rotates on two axes, one is the rotation of the carriage for 10 minutes, and the other is to rotate by itself in the course of 31 days. The moon is engraved with 288 faceted “Jacobs” diamonds, composed of two halves: a black diamond on one side and a white diamond on the other.
Essentially, on the next arm is a highly sophisticated second hand, in the form of a painted magnesium globe, which rotates around its own axis once in 30 seconds, just like a barbecue spitting water, while rotating around the main axis at the same time . There is a small figure of an astronaut on the opposite arm, which rotates on the same 30-second axis. Both also rotated around the dial for 10 minutes.
The last one is a three-axis tourbillon. It has two cages. Each cage rotates once in 60 seconds and 5 minutes, while completing a 10-minute rotation around the central axis.
In addition to various complications, the spacious case is ideal for the carillon minute repeater. Although the bell of the prototype needs to be tuned, the ventilated space inside the box can still emit a loud and clear sound.
Although the fake watch is large, the repeating device is surprisingly flat, integrated into the back plate of the watch, and the sound of the gong rises toward the crystal.
The minute repeater is activated by the sliding cover installed on the left side of the case. In contrast to the traditional minute repeater with two sets of hammers and gongs, the carillon has three sets. The low-key sounds very small, while the quarter of the bell is struck by the triple bell, and the high-minute is hour.
The gong is the cathedral gong to be activated. It is almost twice the length of the traditional gong, which produces a richer, deeper sound and longer reverberation. One of the challenges of building a cathedral gong is to surround the movement without touching each other, and the case and movement do not touch each other. The three gongs of the astronomer master gracefully hovered upwards on the titanium metal base plate, giving a wide view from the side of the case.
In addition, the minute repeater is powered by a patented tapered ratchet barrel, ratchet and pawl system. It also has a patented double safety system that protects the mechanical device during the timing sequence and disengages the time setting device to prevent damage to the movement when the crown is pulled out. There are a pair of hinge lugs for winding and placing the watch on the bottom cover, and a rotating wheel at the bottom for setting the moon phase. After fully winding, the swiss copy watch will run for 60 hours.
