I've thought about going on a road trip to see A. Lange & Söhne watches. I've narrowed it down to the two places nearest to me: Wempe in Düsseldorf, Germany and the ALS boutique in London. However, the Wempe is a 1,5h drive, and the Boutique is 5h away. Is it worth the extra time to go to the boutique instead of the Wempe? Any experiences with these shops are also very welcome and appreciated.
