The RM027-01 Tourbillon, The baseplate of this is attached to the case by 4 braided steel cables, each with a diameter of just 0.35 mm. These cables are held taut by an ingenious mechanism of tensioners (located at 3 and 9 o’clock) and pulleys, which act like pylons positioned at the four corners of the movement. Each cable is fixed to the tensioner, and passes over the upper pulley and into the movement, before returning via the lower pulley to finish in the lower flange. Once the watchmaker has threaded the cables, he tensions them by rotating the central tensioner ring using a special tool. Designed to stay in suspension inside its case, the calibre RM27-01 can withstand accelerations of over 5,000 G,  Just to give you some insight of  how much that is, a human can only withstand 46.2Gs, Mindblowing
