The vintage explorer I ref 5504, different versions were produced, matte, lacquered, etc ... A true collector reference. This one is among the first with a gold-scripted lacquered dial, swiss only chapter ring and exclamation point from 1959, strong patina on the 3_6_9 explorer markers, the rarest configuration for explorer I ref 5504. The watch has its orignal radium hands very rare and it s gilt dial is not relumed all radium active on the geiger!
