This 60's Technos Sky Diver was made by the ecole d'horologerie in Porenturry, Switzerland, and was a test watch, which was made by student watchmakers of Porentruy (Jura watch Valley)
 
The dial on this watch is unreal, the patina, with double lollipop is pure candy for the eye, and the large lume plots against the gloss black dial really pop in the sun.
 
The case is nice overall, and has had maybe one polish over time, but is still in thick condition. The bezel is in great shape, as is the overall condition.
 
This is one watch that won't come around again. Grab it whilst that radium is still hot !
