Whenever I get a free minute anywhere I happen to be, I try to make time to visit those under the radar watch shops. I'm not talking about the Tourneaus of the world - more like those tiny vintage camera and watch shops that sit on the eighth floor of a church in the Ginza district of Tokyo. While in San Francisco, I had the pleasure of visiting the offices of vintage Rolex specialists HQ Milton - and it happens to sit on top of a pawn shop in the Mission. But believe me, it's not what it seems.
