Gianni gave quite a good price range in his post - mine was towards the bottom end of that range but then I thought I'd bought quite well.

These manual second generation Carreras are still a reasonable buy in the world of vintage watches, they still quite often go for sub-€1000 (about ~$1250). That would be for one in at least good condition, you might pay more for one in very good and of course more again for a mint one. They are pretty robust and resilient watches too, but bear in mind as with pretty much anything getting on forty years old, they appreciate a bit of care and attention now and again.

A good choice in terms of size too - we've become accustomed to modern watches getting larger and larger and some vintage watches can seem small to modern sensibilities (though I'm fine with a first generation Carrera on my just above-average wrist, some people aren't), but these are a good familiar size.

Feel free to post any other watches you're considering up, someone here will be able to comment on them.
