In watches refers to the ability of a watch to keep consistent time regardless of the power reserve or the amount of winding. A watch with good isochronism will maintain the same accuracy throughout its running time, this is achieved through the use of a high-quality balance wheel and hairspring system, which ensures that the oscillations of the balance wheel remain consistent and regular. Isochronism is an important quality in a watch as it ensures reliable timekeeping and accuracy over an extended period.
