This listing features a classic vintage Seth Thomas Metronome de Maelzel, a timeless musical accessory. Crafted with a beautiful wooden case, this mechanical metronome is a Division of General Time Instruments Corp. product, originally from Thomaston, Connecticut, U.S.A. The iconic pyramid design houses a pendulum mechanism with an adjustable weight, allowing for precise tempo settings from Largo to Presto, with BPM markings ranging from 40 to 208.

The original instruction label, which also serves as the back cover, is present and fully legible, detailing its use and the manufacturer's information, including the Pacific Coast Sales and Service Office in San Francisco. This piece shows signs of age consistent with a vintage item, including minor wear to the wood and some patina on the brass elements. There is a visible crack on the bottom edge of the case (see images), but it does not appear to affect the structural integrity or functionality. It is offered in its original, working condition, ready to be a functional tool for a musician or a charming display piece for a collector of vintage musical instruments and accessories.
