Characteristic Beta21: ESAQuartz

WHY IS IT IN OUR MUSEUM? It is a heavy goldwatch with the original Beta21-movement for ESA / ETA, the biggest CEH-shareholder and the most important Swiss movement-maker for decades.

The starting-point of Swiss quartz-watches, ten years before the same company made the record-thin watch Delirium (used by Concord, Longines, IWC & Eterna) and twelve years before the Swatch. Indeed, Ebauches SA (ESA / ETA) was not only the most important participant in Beta21 joint-venture but also is one of the most relevant movement-producers, nowadays.
