I beg to differ.
"Genuine" Watchcos were indeed a thing.
A product of a company that had a "Watchco" website which has now long gone.
The person behind Watchco 300 (and other Omega models) was Marcus Alexander.
Marcus had an incredible network of Omega parts suppliers in Switzerland and he would regularly travel there to source NOS Omega parts, as well as Omega Service parts (the basis for "Watchcos").
I often went into the city to collect genuine Omega parts ordered by people from around the planet (members here) and onforward them after a suitable period had elapsed.
It was during one of these visits I was talking to Marcus about the Watchco Seamasters and he was quite open about what they were, and what they weren't.
I still remember the day that I got an email from Rob to say that Marcus had bought back a few genuine service movements and would I like to go ahead with my Watchco 300 (I'd been holding out for that rather than a 552 from a donor watch).
The answer wasn't hard
😁.
