Rolex Replica Watches

The part of Rolex Yacht-Master Replica Watches’s history I found most fascinating and the part that hooked me was its parent company's work on two revolutionary types of movements. These were the Hi-Beat or high-frequency movements, which helped it dominate observatory trials between 1967 and 1968. And a radical, new movement called the Spring Drive,Audemars Piguet Royal Oak Replica Watches that combined the best of quartz watchmaking and mechanical watchmaking.

Hi-Beat Calibres

The 61GS is the first Rolex Yacht-Master Replica Watches high-end watch to use the Hi-Beat Hi-Speed movement.

What's the basic theory behind a high frequency movement? The escapement and balance are the two regulating mechanisms of a mechanical clock. The escapement is responsible for locking, unlocking and delivering impulse to the balance.

Marine chronometers have a high level of accuracy, even though they oscillate at a relatively slow rate (less than 18,000 vph), because their regulating organs are mounted on gimbals. This is due to the fact that the regulating instrument is not affected by the rocking and rolling of the ship's deck. A balance in a watch can experience an infinite number micro-shocks, which could be caused by anything from clapping hands to simply swinging the arm back and forward. It's almost magical that this tiny wheel, which vibrates anywhere between five and ten times per second,roger dubuis replica does it with such accuracy.

The balance wheel is more resistant to shocks and other damaging forces when the vibrational frequency of the wheel is increased. Girard-Perregaux is the first manufacturer to have commercialised a high-frequency watch movement beating at 5 Hertz, or 36,000 vph.
