I bought this for about £20, but I don't actually know anything about the brand Orly and I couldn't find anything when I looked.
Are you sure it's not pronounced.... If it's running fine and you like it.. it seems a good pickup for 20 quid
Here's another example I've found https://aste.catawiki.it/kavels/11775089-orly-men-s-watch-switzerland-circa-1975
So, the best I've been able to do so far- This page, which is in Spanish, seems to say that ORLY is a brand that was created by the Spanish company Duward. Here's an excerpt (thanks to Google translate)- "The Spanish company, which also produced other series (Progress, Orly ...) and even clocks, started a less glorious course in the late sixties after the death of Carlos Vendrell and the definitive rise to the direction of his offspring."
It arrived. I've given it a shake and it is keeping time but the crown feels very tight. Anyone have any guesses as to why?
