The FHF Part 723 balance staff is a replacement component designed for the FHF Calibre 29 mechanical watch movement.
The balance staff is the precision central arbor fitted through the balance wheel. It supports the balance assembly between the upper and lower jewels and allows the balance wheel to oscillate correctly, regulating the movement’s timekeeping.
This replacement part is suitable for servicing and restoring compatible FHF Calibre 29 movements where the original staff is worn, bent or has damaged pivots.
Professional installation is recommended, as balance-staff replacement requires specialist watchmaking tools and careful adjustment of the balance assembly.
