There is a place for the 5218. As for the vintage Ploprof, I had several problems with the crown, which seems to be the weak point of this watch.
That really is a stunning looking Vintage Omega Seamaster 600 Ploprof.
I'm glad to see it has survived your wrath over the crown issues, as I was getting worried for its future at one point. What is a little issue with a classic vintage watch anyway It's just part of the fun of ownership.

From the perspective of the 600 meters which was was a big achievement.
Not that they invented dive watches but it was a real tool watch that never got traction as a recreational diver tool but a professional tool.
Everyone knows "She sells sea-shells . . .
. . . by the sea-shore" as difficult tongue-twister. Well, try saying "Ploprof" ten times.
