I've tried a couple of tool watches that I picked up at the "Sales Corner". They were all nice in their own way but I'm ready to admit that the watch I've really been hankering for is the 856 (non UTC) on a rubber strap with a small clasp.
I did join in another thread here a while back and voiced my opinion that by the time you pay VAT refund fees and customs and get your new watch home to the USA that the savings are pretty modest and probably don't make up for not having a USA warranty. However I've been wrong about a few things in the past. Just search for my handle and the phrase "catch-and-release" to confirm my fallibility in the watch department.
So...if you bought your Sinn in Germany and saved a bundle would you please share your experience? I'll by flying through Frankfurt in about 10-days and could probably just squeeze out the time before my connecting flight to Vienna to visit the Sinn shop.
