Over the weekend my wife and I traveled to the National Association of Watch and Clock Collectors Museum and then onto Washington DC to see the new Newseum. The former is a wonderful day of vintage Tall Clock and PW watch viewing. The NAWCC Museum had a special exhibition of Presidential Watches and Clocks going back to George Washington through Richard Nixon. The Newseum is new venue Washington DC and a must see. It chronicles the history of news dissemination from the dawn of man to today's multimedia methodologies. It was fascinating.
Before I left on Friday morning at 10 am, I hand wound all of my IWC's. Upon my return at 6 pm on Sunday, 56 hours later, only my 7 day reserve Portuguese, the 7 day reserve Portuguese PPC and, to my surprise, my new VC Portofino were still running.
I was quite impressed that the hand wound VC Portofino had a longer power reserve than the 3227 Inge, the 3717 Laureus Chorno, the Power Reserve Saint Exupery, the Porsche Design Chrono and an old cal 89. The difference it when each watch stopped was up to six hours difference.
Of course this is not a scientific experiment in any sense. Is it possible that a new watch with a new mainspring will hold its power longer and have less reserve as it ages?
