Did Omega make an "Olympic" 3515.20?

Hi, sorry if this is an sophomoric question but I've searched the forums, google and the vintage archive and don't find a clear answer. I live in Japan and this model of watch is showing up a lot lately on amazon Japan, rakuten, yahoo auctions and several other online sites. I like the white face and I had never seen a model like this which makes me wonder if it is legitimate. This link is one of several auctions showing the model (google chrome will translate it for you) http://page18.auctions.yahoo.co.jp/jp/auction/w118251704

Strangely, some of the sites describe it as a "mechanical, automatic quartz" movement. The reference is always given as 3515.20. At this point, I feel like it is a bogus model but the fact that some larger reputable online stores are listing them makes me reconsider. If you have any advice or information, I would be grateful.

Thanks

Standy, Thanks for the response. I did look at the images but what was troubling me was that many of those images went right back to the same sources and region as the watches I see for sale. I searched the forum threads using 3515.20, 3515.20.00, olympic and several other combinations but didn't come up with anything. Since I'm in Japan, it would make sense that I see more of them if it is a Japanese release (the auto date reduced is everywhere here) but do you know anything about the movement? I've seen it described as "mechanical winding", "automatic", "self winding" and "automatic quartz winding". Thanks for taking the time to write back, I appreciate it and if I can do anything for you in Japan, let me know. Mark

I still have a lot to learn. I just read that there is an "automatic quartz movement", used in some Omega watches as well as others. I had no idea. Still processing it and it may be the brandy but I don't believe I like the idea.

I should have included that wikipedia link, that's where I learned that there was such a movement. If it goes low at the auction, I might take a shot at it. I'm looking for reviews now about the combination automatic and quartz movements. I presume that Omega uses the version with the capacitor but details are scarce. Have you ever owned one of these or any other watch with the automatic quartz movement? It seems that the main purpose of the pendulum is to provide power to the quartz movement. I'm thinking it is somewhat like a battery-less quartz movement.

Archer, Thanks for the reply. Here's how the autoquartz got into it: There are quite a few of these going up for auction or available at online stores here in Japan. In the descriptions of the watches, they often describe them as "automatic quartz". For example, here is an
English listing on Amazon which, in the details section, describes the movement as an "automatic quartz". http://www.amazon.com/Omega-Speedmaster-Stainless-Chronograph-Automatic/dp/B00AM0GMHI
