·Might add that I find this thread a good source, best I found!
Nothing like on the dash but this site is where a lot of "common knowledge" comes from: http://watchexpertise.com/oldlonginespassion/Longines_Passion/Referenze.html Maybe I will do a thread on waterproof 13ZN references.
Ah yes, I remember seeing this one. Agree, with @Radiumpassion, another ref. 5415. Dial and hands look original and I do not necessarily think that it has been re-lumed.
If a 13ZN monopusher ever was featured in a cartoon it would look like that😁
