Close -- it's a 14722. The serial no. dates the watch to 1959/1960, it runs on a Cal.520. I have some evidence that the movement was actually manufactured in 1957, since the factory which made the 520 was permanently closed down in 1957. So, maybe, this is kind of a 'birth year' (1957) watch for me

One in a million......... or to bring a Dairy flavour to it ( rather than pepperoni) a fine aged vintage cheese. Wish it were mine.
