Etna “Light Jet”

Swiss Watch Fair 1972 BF 210
This watch incorporates its own light source; it not only serves to light the dial but, with its powerful beam, for map reading, finding keyholes and so forth. A tiny bulb is lodged in the case in such a way that its light illuminates the entire dial. The power source is constituted by twinned 1.5 V batteries hidden under the bracelet links. This model is available in various versions: selfwinding, ladies model, chronograph or alarm watch (ETNA “Light Jet”)
