Here is a 1940’s reference 6020 30mm. (boys’ size) stainless steel ROLEX OYSTER. The 10.5 lignes, hunter style manual winding ROLEX movement was just cleaned and is quite accurate. Notice the perfectly re-done dial with pencil hands and sweep seconds. Note the super oyster crown…(only produced by ROLEX for 2 years). The stainless steel case with ROLEX OYSTER screw back glistens without scratches! These “boys” size ROLEX OYSTER watches were designed for soldiers going overseas in WW2. Their smaller size allowed the soldiers to fight whilst not banging the watch. These ROLEXES are becoming harder and harder to find in clean condition!
