Hands-on tourbillon history 6 Harry Winston (Harry Winston)
Like its predecessors, Histoire de Tourbillon 6 is clearly a classic watch. Many magnificent works may not see the most wrist time. But this does not make them appear so exaggerated. This watch basically consists of two separate parts. They can be recognized geometrically as a circle or a square. Like every part of the Tourbillon History series, every part of the Tourbillon 6 History Edition explores and develops the concept of the tourbillon.
The sphere on the left side of the case is part of a three-axis tourbillon, which means three different spins. The balance wheel cage rotates every 45 seconds in the second cage, and the second cage rotates every 75 seconds on its vertical axis. The pair is housed in a third spherical cage that rotates every 300 seconds. Who remembers the prime decomposition here? [45 = 32×51] [75 = 31×52] [300 = 22×31×52], which gives us 22×32×52 = 900 seconds (or 15 minutes). The balance wheel takes a long time to complete its rotation, which is neat. Complete four full spins in one hour, less than 100 times a day!
On the right at 1 o’clock is the karussel (carousel). For those who are unfamiliar, karussel and tourbillon are similar because they are designed to counteract the effects of gravity by rotating the balance wheel and escapement. The main difference between the two is that karussel relies on other gears to rotate, while the tourbillon is independent. Histoire de Tourbillon karussel spins at a speed of 30 seconds. Below it, the second chronograph function for hours and minutes can be individually set via the crown (the second crown-note that there are two). copy watches
The interesting mechanism of the second time zone is the interaction via buttons at 2 o’clock. Once activated, the button resets the hands to zero, so it can be used as a 12-hour chronograph, which is an interesting concept of long-term engagement.
The case is made of titanium, with a thickness of 55 mm x 49 mm, with high titanium content and high palladium content. Once again, we realized that its size does not fit the average cuff. The finishing is the same as Harry Winston’s expectations. Round ball brush, polished side of wine barrel.
Shown on the back is the PVD titanium alloy bridge. The surface is sandblasted and can be wrapped with dual coaxial barrels. The HW4701 manual winding movement contains 683 parts and moves each balance wheel at a speed of 3 Hz (21,600 vph). The power reserve of the tourbillon is 80 hours, while the power reserve of Kassel is 70 hours.
The Histoire de Tourbillon 6 (Tourbillon History) produced by replica Harry Winston is an important successor to the historic exhibition of Histoire de Tourbillon (Tourbillon).
