[Case] The size of the watch is 44mmX15.5mm. The exquisitely polished watch case is noble and generous. IWC is proficient in IWC’s original polishing skills, with smooth lines and pleasing effects. The knurled crown is re-engraved in place, retaining the original beauty of the original, and the operating feel is comparable to the original. [Best selling point] The tourbillon flying in the sky at 9 o’clock can offset the negative impact of gravity on the balance wheel, thereby effectively offsetting the deviation of the time speed, making the watch extremely accurate. The IWC factory perfectly reproduces these 81 parts to constitute the tourbillon device, which is placed in a circular window at 12 o’clock just like the original product. The rhodium-plated escape wheel and the nickel-silver stationary wheel splint are both painstakingly hand-cut. The parts are exquisitely polished, including a large number of polished inner corners and bevels, and the details are comparable to genuine products. [Strap buckle] The strap is made of top-grade Italian small leather, with a soft and delicate texture. The hand-sewn silk threads have clear lines and are even and regular.
