TAG Heuer Mikrogirder has revolutionized mechanical time keeping with its 5/10000th chronometer. With 7,200,000 beats per hour versus the standard 28,800 beats per hour of a regular watch is amazing that it does not just self destruct. The obviously had to reinvent the wheel in actuality. They devised a watch that re-engineered time keeping without a balance wheel, hairspring and came up with a new mechanical way of mechanical regulation in order to create a time piece accurate to 5/10000th of a second.
