Suppose if every single piece is genuine Omega, they would probably know that it was a diy, but the customer could argue they had it serviced x-number of times til Trigger’s broom looked original.
Better yet, simply that they bought it in good faith like that as all parts were Meggers inside.
isnt a frankenwatch a watch that has some genuine parts and some fake parts assembled together?
is it a frankenwatch if Omega itself accepts to service it?
