Anchor escapement is, an increase in amplitude of swing causes a slight increase in period of a pendulum due to circular error, and that this can compensate for the decreased period due to isochronism. Due to this effect a carefully adjusted anchor escapement with polished pallets might be more accurate than a deadbeat. This has been confirmed by at least one modern experiment. Anchor escapement In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each
Escapement was recognized as a disturbing influence on the isochronism of the balance. Purchasers no longer buy mechanical watches primarily for their accuracy, so manufacturers had little interest in investing in the tooling required, although finally Omega adopted it in 1990. Although a highly ingenious escapement design, the Daniels coaxial nevertheless still needs lubrication to the lever pallet pivots. In addition, because of its geometry the impulse wheel can only have a limited number of teeth, thus it is necessary to have an extra wheel and pinion in the wheel train the pivots of which also need lubricating. Therefore, the advantages
