Open balance watch

Open balance

— this feature means that the watch face has a transparent window that allows you to see part of the mechanism. Usually, such a window reveals exactly the balance — a special pendulum wheel, one of the most important details of the hardware (hence the name). Such a design detail is mainly decorative — it gives the dial an original appearance. In addition, during operation, the pendulum wheel constantly oscillates — this not only visually "revives" the dial, making it more dynamic, but also allows you to control whether the watch is running (this feature is especially useful if there is no second hand).

A similar function is performed by the Skeleton case (see above); the difference lies in the fact that in Skeletons almost the entire mechanism is made open, and not a separate part of it.
