Case, movement, and dial signed

C&I USA Rivet Bracelet stamped '71

Untouched and all original gilt dial with attractive patina

Small areas of radium loss to the 6 and 9 numerals, as well as the 11 and 1 markers

The hands were previously unstable and damaged and so have been relumed to match the dial

The watch nonetheless reads high on the geiger counter - around 1800 pcm confirming the radium to the dial 

The case is evidently unpolished, as (especially) an early Explorer should be showing a life-lived, and shows wear from age - the serial and ref. numbers are clear and visible, the lugs and bezel remain thick and correct

Service history unknown, the watch though is running strong with an amplitude of 220 running at approximately 3 seconds per day
