Well one would ask, How do you know it is an original crystal?
Are you asking me or Warren? If me, that shot is from a member who bought from an AD we all know. I've got a few shots of my vintage watches too, and they all look close to the shot I posted of the Speedmaster's symbol.
Would you really want a car with 50-year old windshield wipers or the orginal oil filter inside?
Depends if you're gonna drive it or not. 😉
