You are absolutely right, but these are the only photos I have for now. I will meet with the seller to see the watch personally, but I want to have an idea what this is, before meeting with him.
1. interesting integrated bracelet @nickgr but more importantly here's another view
2.
Do the usual digging/research before you buy though ... didn't see a date example but its the dial that intrigued me

Thank you for your answer. I find both the integrated bracelet and the dial very interesting. In a way this watch reminds me of the modern Aqua Terra Omegas. The watch in the video you added, is very similar so at least both watches are from the same era.
Ok, I bought it and here are the photos of the caseback and the movement I took
Movement is 1010 as @X350 XJR mentioned, and it looks to be in very good condition. Watch so far keeps good time.
Well I googled the both the case numbers 166.0266/366.0866 either show no result or entirely different looking Seamasters. Omega Vintage Database shows no result for either case number. Movement serial number dates the watch to be from about 1979.
