Hi Fleaman,
Nice vintage collection you got there
I used to have a lot of vintage watches when i was working in UK (a lot vintage time pieces you can get there compare to Msia) I used to have some Omega, Oris and SEIKO.. i sold most of them when I started with modern Rolex (mostly traded) but I still keep 1 Oris (my first manual winding vintage Oris), 1 vintage SEIKO and 1 or 2 UK brand vintage
In my opinion, unless I'm a watch-maker or know how to perform service to the watches, otherwise, it will be hard for me keeping many vintage and honestly, i can't tell if the movement is real (parts) or aftermarket... but then again, i think it's cool if someone wearing a vintage (like your Vulcain) with some good looking design!
Thanks for sharing
