AION inside Bucherer is the World’s Largest Rolling Ball Clock, according to Guinness. This place sells every luxury watch under the sun. I had a good time drooling as I display-shopped. If that’s a little steep for you, go to a higher floor(7?) for Swiss Army knives and other more affordable souvenirs. Someone mentioned to me that London was actually a better deal for Rolex watches(after figuring out tax and all that), but then you wouldn’t have your Rolex straight from Switzerland.
