Any vintage watch shops in London, Brussels or Amsterdam?

[JParm]

Headed there in a few months and I want to see if anyone here has had success with vintage watch shops in those 3 cities? I'm looking for places that won't break the bank per se, but have a decent enough catalog to warrant a visit while on vacation.

Also, any other recommendations on shops to visit that are unique to the area (leather, clothing, shoes, etc) would be much appreciated!
