S.H.
路I'm trying to find something useful concerning vintage Tissot watches and these days, google is chock full of commercial links, FS ads, etc... a real bazaar of bullshit but I'm coming mostly empty of interesting bits of info.
Here is what I found so far:
A catalog of vintage PR516s / technical watches from the 60s-70s :
http://chronomaddox.com/tissot/manual/tissot_technical_watches/tech_wide.html
Something for older Tissots:
https://www.fratellowatches.com/vintage-tissot-information/
Not much else... I'd like to find something with more depth concerning the pr516 lineup, its history, something about the various refs, bracelets numbers, bezel variations, etc.
Feel free to post here your links or your docs! Also, did anyone here order an archive extract from Tissot?
