Dual direct escapement
The watchmaker and watch designer Ludwig Oechslin developed the so-called dual direct escapement , which is also sometimes referred to as a double direct drive , and presented this innovation for the first time in 2001 at the Basel watch fair, implemented in a Ulysse Nardin watch .
It is an anchorless free escapement with two escape wheels . With the dual direct escapement, the force impulse is transmitted directly from the hollow teeth of the escape wheels to the balance . The first escape wheel is driven by a drive from the gear train, the second escape wheel is driven by the escape gear rims. A ratchet between the escape wheels and the balance causes the wheel train to be inhibited while the balance swings freely.
