There's a Tiffany's store in the Oriental Plaza shopping mall in the middle of Beijing, next to the Grand Hyatt. This week I went in to find out how much it would cost to have the crystal of my watch replaced (it cracked recently when it fell out of my pocket, and now there are several lines running across it and a 4 mm hole in it). The staff made some inquiries and told me that it would cost 1500RMB (approximately US$220) and take over six months, as the watch would need to be sent to America.
There's a great watch repair stand in Grand Central station that replaces watch crystals in a matter of days, at very reasonable prices. If I can't get a good watch repair recommendation here I'll be taking my watch to NY to be fixed. I'm not sure when exactly that will be, but on my next trip to NY you can expect me to find my way to Grand Central.
Maybe I'll combine the visit with a slice of Junior's Cheesecake in the basement.
