It actually came from Rolex Forums not WUS, one of the most active Omega communities at the time back in about 2009 was TRF and Trev and I met there as I had a 1680 sub and Trev had I think a 116200 Datejust.
It was a bit embarrassing at times being Omega fans in a corner of Rolex forums but the people were great and we enjoyed it. One of the difficulties though is we had people posting their new Planet Oceans and replies from people like “no bad but it’s a shame you didn’t save up and get a Submariner” as the perception of many people there was you only buy an Omega if you couldn’t afford a Rolex.
There was actually a thread like that I relied to saying something like “you know a lot of people just want an Omega and prefer it to a Rolex especially with the new Calibre 8500 being more modern than the Calibre 3135” and I ended up getting a pm, not rude necessarily but basically a mod asking me if I was trolling or trying to start trouble. This was in the Omega sub forum I might add. Trev was a very talented creative designer and I was a backend / server guy so between us we decided to start work on a dedicated forum and registered the domain.
A guy not long after suggested creating an omega forum and did, while we were still doing development and design work in 2010 but it was a bad service covered in ads and quickly died off.
We launched in March 2011 and it was initially just a group of around 30-35 of us from the TRF Omega subforum and very slow with repetitive what is my watch worth questions and I’d often be googling like mad to help answer them as there were no others at the time. It actually makes me laugh sometimes when people say what is my watch worth threads are too common now because the first 100-200 threads on this site from early 2011 were nothing but that!
