Once in a lifetime. Trying the George Daniels Spring Case Tourbillon for size while listening to the Derek Pratt for Urban Jürgensen Grand Complication. Thank you @phillipswatches and @lmcommunications. And then there was the Omega Speedmaster ‘Flightmaster Prototype’ and the Vianney Halter titanium double balance prototype... one-of-a-kinds for sale this weekend at Phillips Geneva. #georgedaniels #derekpratt #urbanjurgensen #omega #speedmaster #vianneyhalter #telegraphtime #watchpro #britishinstituteofhorology #bhi
