These watches are quite interesting and the 3 sub-dials versions are quite rare. What is most rare of these is having an original dial from the 50's on a snap back caseback. The watch is very clean with minimal signs of polish and overall the watch is very solid. The dial is clean with the Serif Swiss Made signature at the bottom and no visible flaws overall.
