If you like Soviet watches you'll probably enjoy this index of movements: https://17jewels.info/ I collect mechanical watches and have a fair number of vintage Soviet watches in my collection - Rateka, Vostok, Poljot, etc. Cheap, reliable, and often with striking designs. (Today's watch is a Poljot - Russian: Полёт, literally meaning "flight", is a brand of Soviet/Russian wristwatches, produced since 1964 by the Firs…
Any recommendations for where to purchase these vintage watches? I've always thought they were beautiful but never sure where to find legitimate sellers (despite googling a bit)
To get started just enter "soviet vintage" into the search-box. Once you have some results click on "Filter" and you get the option to set "Location: European Union", "Max Price: €100", etc.
There are a lot of regional variations, so I use chrono24.fi, for example. But the content is the same - I think it's just the default location and currency that changes based on TLD.
The site has been around for many years and is well-regarded, but even so I don't think I've ever paid more than €1000 for a watch there. Just in case.
Edit: Main thing to pay attention to are the dimensions of the watch. Watches from the 40s-80s tended to be smaller. So you'll find diameters of 34mm, 36mm, etc. Most people prefer larger watches these days. For me 36mm-42mm is fine, but that's because I have thin wrists. But I know looking at photos can be misleading in terms of diameter/dimensions so read the details.
Edit #2: This is what I'm wearing today, which cost me around €70 - https://tinyurl.com/dd7bnthx
