Jacques Launched The World’s First Spherical Tourbillon Watch

Jaeger-LeCoultre, a 178-year-old watch brand, not only asserts itself as a defender of traditional watchmaking technology, but also is one of the pioneers in the field of precision timing technology and design. Today, this watch brand with outstanding quality, innovative concepts and delicate craftsmanship once again presents a masterpiece, launching the world’s first GyrotoubillonI spherical tourbillon watch.

The new watch uses a 45 mm diameter case, which is made of 950 platinum. The crystal bezel is embedded with white TopWesselton diamonds, corresponding to the strap, lugs and crown. The sapphire crystal mirror can be seen through the mirror. Shaped dial, dial with hour, minute and second display, time error display, double-handed jump-back perennial date display, jump-back perennial month display, power reserve display and other functions, and below the spherical tourbillon device. With a hand-stitched crocodile leather strap and sapphire crystal case back, the case back has a leap year display. In terms of power, the watch is equipped with a Jaeger-LeCoultre 177 manual winding movement with a diameter of 36.3 mm and a thickness of 10.85 mm. It has 512 components and is equipped with two combined winding discs. 8-day power reserve. Limited to one.

Perennial date display
The date scale is set in the center of the dial. To avoid interference with the operation of the central hour and minute hands, the date is marked by two jumping hands: the left hand indicates the first half of the month, and the right hand indicates the second half of the month; In the standby position, to avoid confusion with the pointer in operation; at the same time, the two needles are divided on the 16th of each month, and on that day, they are pointing at 16 for 24 consecutive hours, and at 00:00 on the 17th, the left pointer instantly jumps to the starting point. The left hand pointer goes to 17.

Time error display
The earth revolves around the earth all year round, and its orbit is an elliptic curve, and the angle of the earth is slightly inclined, which makes the actual length of each day slightly increase or decrease. The 177 movement of the GyrotoubillonI watch has an engraved sun-shaped hand. The hand is controlled by an outer circular spiral rolling cam. The cam rotates on the bearing at the speed of a cycle every year and detects it constantly. The correct position, the time error is marked on the dial.

Sphere Tourbillon
This tourbillon consists of 90 parts and weighs only 0.336 grams. The outer ring is made of extremely light aluminum alloy, which rotates around the shaft every 60 seconds. The inner device is made of titanium alloy and aluminum alloy. The balance wheel, balance spring and escapement structure, the main axis is 90 degrees from the former, and it rotates once every 24 seconds. The matching Breguet balance spring freely vibrates at a cycle rate of 3 Hz per second (that is, 21,600 vibrations per hour). In addition, the watch is equipped with six anti-vibration devices, tourbillon aluminum outer ring bearings, inner rotating device and so on.
