Speesmaster question
Just considering shopping 3510.50, is this original Moon watch? Checking some out on the Bay, should the back say "Certified for Manned Space Flight" around the Seahorse? Is 3510.50 the right model # for the no date, manual wind, Hesalite crystal watch? How is this movement? Tough? Would you guys buy a used one? I've got a couple of TAG auto's that I absoutly love but this watch has been drawing me in lately and there might not be any hope. Any and all correspondence is greatly appreciated.

A dream come true at last !!!! (kinda long)
As some of you may know the 5960 has been my grail for a long time, almost from the time that I was released. Prior the 5960 I appreciated the mechanical aspect of Patek, but the designs left me cold. I knew that Patek was ¡°The Best¡± but I had a hard time appreciating the simplicity of a simple time only Calatrava, and the perpetual calendars were all a little too mature for my taste. It seemed to me that Pateks were designed to be worn by my father or grandfather, not me. All it took to forever change my mind about Patek was one single ad on the back of a Robb Report ¡°Watch Collector¡± issue. I couldn¡¯t believe that was a Patek, the dial was so modern with its minimalistic windows for the calendar, far cleaner than the 5146. The mono counter of the chrono was cleaner than 5070. Even the choice of colors was very different, slate grey with a touch of red and blue. I could hardly believe this was made by the same Patek Phlilippe that made watches like the 5140 that I felt only older men

AP service and parts for old watches
Does any one knows for how long will AP officially or unofficially service their watches and stock the parts for it? 20 years or 30 years? Or no limit? I heard that Rolex guarantee a 20 years time frame but typically can do much better than that. PP and Vc typically service their watches for life as I understand including some very old vintage pieces. This is obviously a concern if I move to the higher end and most costly watches because what I am buying now will becoming old watches in 20 to 30 years time. It will be good to have the assurance that my watch can be serviced at a much later period. By the way, I seldom heard of people talking about Vintage AP watches in this forum as well as others and it's seldom mention in watch magazines as well, only the latest RO or ROOs. Just wondering..

Pam 468 investment
Will the pam 468 be a good investment to make as there was only a 100 produced ?
