Blancpain Classic 66228 automatic true tourbillon watch. The size of the watch is 42mm. The front and back are made of sapphire crystal glass mirrors. Through the enlarged floating tourbillon frame at 12 o'clock, you can see the full view of the balance wheel and escape wheel from the dial and feel the beauty of machinery. The tourbillon rotates for one revolution per minute (360 degrees) to counteract the influence of dispersed gravity on mechanical parts, thereby improving the accuracy of the watch. Both the dial and hour markers are made of enamel, which is gorgeous and shiny, and the hollow willow-shaped hands are light and elegant. The overall high-end atmosphere, excellent classic.
