Possibly my highlight of all of Baselworld 2012, was this sublime pocketwatch by one of the greatest watchmakers of the past 100 years, Derek Pratt. Completed in 1987 for Urban Jurgensen's late owner Peter Baumberger, it is one of if not the best pocketwatch I have ever seen in 25 years of being in this field.
Made for Urban Jurgensen in 1987, with a remontoir.
