Notes on the Tourbillon
A: after receiving the watch, the first manual winding about 90 times, the correct way of winding is to adjust the handle is not pulled out of the case, to the 12 o'clock direction twisting, (such as 1 lap 360 degrees, about 56 laps) until the clockwork all tightened in the middle can be. (Note: the clockwork fast all hold tight in the middle, this time on the clockwork need to be careful strength, once hold tight resistance is very big, big enough to screw, that is, on the full, can not force on the clockwork, in order to avoid screwing off the heart or the clockwork on the explosion, resulting in damage to the movement.) Full winding, this time the watch continuous running time can last about 72 hours, but because after 48 hours, the degree of looseness of the clockwork is larger, this time the clockwork torque will fall, will affect the precision of running time, it is recommended that in 48 hours or so, you can manually give the clockwork on the full chain again to get the best precision of running time, it is best to get into the habit of winding up and down the clockwork every day. The tightness of the winding can be directly observed by naked eyes.
Second: After winding the watch, the crown will be pulled out to adjust the time, and then gently pushed back to the centre of the handle.
Third: Tourbillon watch is an extremely complicated precision mechanical timekeeping device, it is recommended to be limited to daily wear, avoid using it in intense sports, avoid violent vibration or rubbing against hard objects. Do not wear the watch for seawater swimming or diving, so as to avoid corrosive seawater loss of watch colour and waterproof ring and other parts! Cannot operate the crown under water. Keep away from magnetic wall field equipment, such as stereos, magnetic sports equipment, etc.
