. . . will tell it again.
My pal Scott bought the very same Seamaster about seventeen years ago from an AD. Wore it for a quite awhile as an everyday beater, then one day scratched it on a rock while surfing. Shortly afterwards, he put it up for sale and let go of it.
A few years later he missed his old companion, and searched the usual sources. He came across a 2254 on TimeZone's FS forum. When he took a close look at the photos, he was amazed to find his SM staring back at him! He could tell by the scratch.
He ended up losing a few bucks buying it back from the third owner by paying more than what he sold it for.
