Collecting watches is hardly a full-contact sport, but there are perils for hapless buyers. As collectors we are victims of desire: we see pieces out in the wild or here on Monochrome-Watches.com and lust sets in.

What if your desire takes you beyond the new and pre-owned case into the realm of rare and vintage watches?
