This vintage Vibrograf B 100 watch timing machine is a specialized piece of horological equipment designed for watchmakers to test and regulate mechanical timepieces. The unit features a paper tape printing mechanism, beat-rate selector buttons, calibration controls, and timing adjustment controls. Also included is an Accutron Vibrograf watch-holder/pickup, designed for testing tuning-fork watches such as Bulova Accutron movements. The holder works with the timing machine to pick up the acoustic/electronic signal from the watch and allow the machine to measure timing performance. The Vibrograf B 100 is an excellent collectible piece of vintage watchmaking equipment and would be particularly appealing to horology enthusiasts, watch repairers, and collectors of professional watchmaker tools. Condition: Shows vintage wear including scratches, discoloration, oxidation, and general signs of age and storage. The electrical system, motor, paper-feed mechanism, pickup, controls, calibration, and printing function have not been tested. Paper supply and other consumable components may require replacement. Please examine all photos carefully for completeness and condition. Untested; sold as-is for repair, restoration, parts, display, or collection.
