Interesting to note the advancements made to the 5550P. The 'clean' room reminds me of a highly infectious disease centre or a top secret biological testing area instead of a process in watchmaking.
I like the watch in it's entirety and kudos to Mr. Stern for not putting a premium on this new technology. Acquiring one from an AD however,may pose a bit of a hurdle, like the other Advance Research pieces.
cheers
