What time is it? Watches and horology

I saw the Ploprof in Carter-Marsh, put a picture in this thread and a discussion started.

Freddo recommended this site, a collectors guide to the Ploprof, and the author of said site, and others - he's a marque specialist.

I started corresponding with the expert, got further details from Carter-Marsh including the serial number on the movement, and the expert (t_solo_t on Instagram) said that based on at records in the Omega archives that this was a service movement.

I went back to Carter-Marsh with this, who had a hissy fit and told me that the watch was actually a super-rare example, which they'd not realised before, and they'd significantly undervalued it so were removing it from sale (with the inference being it was going to a collector, due to it's amazing provenance).

I mentioned this on the thread, Freddo said that (what his recommended expert had said) was horse-shit, had his own hissy-fit and blocked me.

I didn't buy the watch.
