SIGNED BERGEON AND BREVET S.G.D.G. ON ADDITIONAL CUTTERS AND CUTTER CHUCKS, CIRCA 1900

The present watchmaking tool is preserved in very good, fully functional overall condition and mounted on a wooden box with front drawers containing accessories. Its rarity is further enhanced by the additional box with 24 smooth axles.
