Dear watch aficionado.
Here a nice and rare example of a Universal Genève Compax from 1941 in a 46mm case and with the rare silver satin big radium dial by Cadran Stern:
The backside of this original, untouched dial bears the punch mark and code of the dial manufacturer Stern Frères, a master dial maker of the period, famous for their quality and magic of their dials due to little, yet important details in manufacturer. The blank plate is silver galvanized with a vertical satin finish. The recessed subdials are decorated with a fine snailing done by hand with a laze. The plate is covered with a mat transparent lacquer called "sapon" (only on the front, not on the back), which protects against oxidation. Finally all inscriptions are applied by pad printing using different clichés. For the application of the luminescent radium, Stern sent the dial to an external supplier. Only 2 companies existed in Switzerland to do this work. The Lanzett blued steel radium hands were most likely made by Fiedler Geneva, the renowned manufacturer of hands and sole supplier of Stern Frères in this period. The minimal oxidation, especially seen on the contact with the bezel and on the back are natural signs of aging that underline the untouched original condition of the object.
