After much hand wringing I decided to go for this one.
I couldn't really stretch the budget to get a nice Constellation and this Seamaster looked too good to pass up.
Ebay listing: Omega 24 Jewel Model 552 Automatic Seamaster Serial 18212407 Circa 1961 | eBay
I know Seiko much better than I know Omega, despite being a fan of their 1960's watches for many years.
I figure I can always resell it at a later date if my dream watch ever makes an appearance.
I'll know more once received, but can anyone more knowledgeable than I out there give me their opinion on this one?
