Speedmaster Back query
Any reason why the Speedmaster Pro has it's central disc made out of what appears to be an alloy of some sort while my other Speedmaster (Triple Date) has the same material (SS) for it's central disc as the rest of the case?

Question about Guillermin Co in regards to a 1948 ref 96
I recently received my ref 96 back from service and got the Extract from the Archives as well, it was my grandfather’s watch and its been passed down. My dad always thought he bought it in the early 50s, but according to the extract from the archives it was purchased in 1948, which is pretty cool because my grandfather had to flee the Czech Republic and then fought during the war so he had nothing, and he must have done fairly well in the three years from the end of the war to when he bought this.My question is does anyone have information on Guillermin & Co? I see here on the Extract from he Archives that it says the case “112” was provided by Guillermin & Co, and there is no registered case number from PP. It also says that the type of watch is movement only. Does this mean that the movement was purchased by Guillermin & Co, and then cased by them and sold as a Patek Philippe? Any info would be nice, I am just trying to get some info about this watch as

help reorganize the collection - 5167?
getting a litle bit bored with my collection and after adding a 5980, been trying to find reason to get another Patek. I'm quite sure already that my red sub, AP ROO Ti, and the Patek chrono will be for keeps. I'm looking to flip a PAM194 subzilla and an IWC Ingeneiur 3227.What do you guys think? Would the aquanaut be a worthy addition (I know this is a Patek forum!)? Less is more, quality than quantity? Signs of getting old (over 40 now). I'm still inclined with sports watches though and these 4 watch rotation will keep me happy for the time being.Need help. Watch nut alert!
