New vintage purchase

Start here.

Take a look at posts of folks that fell into the vintage collecting world like @DigitalDivider and @Deeperblue .

There are plenty of watches that fall within your criteria. I have no idea what you like or what vintage watches interest you.  I looked at your profile and I still haven't a guess.

All vintage purchases are a gamble. If you pick enough winners you forget the losers. Here is a loser:

I can't get it to run. I will probably sell it and move on.  Here is a winner:

It has just a few imperfections and the mechanical movement is accurate to within 30 seconds a day (good enough for a 40 year old watch). The best part is that the watch cost less than the strap.

Narrow your focus. Why vintage? And, what watch?

I would add two things to the excellent advice from @Aurelian; quartz is no guarantee in the vintage market, and look for watches with a good number of pictures.

I have actually had better luck with mechanical movements in vintage purchases than I have with quartz movements. Just because a vintage watch has a quartz movement, that is not a promise the movement will not need servicing.

It has been my experience that sellers with watches in good condition are not shy about providing plenty of pictures of the watch, from a variety of perspectives. A watch with only one or two blurry pics is probably not going to be in very good shape. A lot of pics is no guarantee of condition, but it is a pretty good indication.

Lastly, just take a chance.

These four were under $200 for each.

These three were under $100 for each.

I do have a number of lemons in a drawer, but definitely have a net positive in the vintage market.

p.s. here is a good post by @WatchYourIntruder on accepting blemishes/imperfections in vintage watches: https://www.watchcrunch.com/WatchYourIntruder/posts/embracing-damage-23678

I have to attack this sideways. On what are you basing the aversion to servicing? What is your experience with that? Is cost or availability a larger concern?

Unless one is in a truly remote area, I'd say to start with whatever reasonably priced thing catches your fancy, working or not, because you really want to find a watchmaker sooner rather than later. What better way to audition them than with some low-end basket case? Once you find affordable and competent service, your world gets larger.

I'm not into vintage watches, so I may be totally wrong, but it was my understanding that it could be harder to get a vintage quartz serviced than a vintage mechanical. Hopefully one of the vintage experts can chime in.

Thanks @digitaldiver, @OscarKlosoff, @Aurelian for the sound advice 

I'm averaging around 50/50 with my vintage purchases.  Oddly enough my most accurate and cool vintage was the cheapest.  I bought a Q Timex from the 70s and all I had to do was change the battery and the watch works great.  The best vintage purchase I made was a fully serviced Hamilton Myron. The watch is beautiful and works great.  For the Quartz I paid a whopping $10 and for the Hamilton $160.  You will find plenty of watches in your price range.

So far I've had 2 out of 28 that had unexpected issues. 

I feel Luck! I had one show up today. I kid you not! This is how it was packed in the USPS bubble sleeve. Not enough Zip-Tie's... The watch was free riding in the bubble pouch.

Just starting on the vintage trail.
