How much do the Rolex watches in this thread typically go for?
The Subs go for $4K to $6K on the secondhand market, the Daytona's probably $9K to $12K...add a few grand for tu-tone. I'm not sure about the vintage Subs and such, but they're no cheaper than a new one.
Sorry to debate, Wraith - I do respect your knowledge and taste... but it is far from a dress watch.
It is a steel cased sports/diver with luminous dial markings for such activity. It is most undoubedly a 135.027 Caliber 601 movement that is held in high esteem as Omega's last no frills, pure, dive watches calibers...without so much as a date window! The 600 Seamaster nomenclature ultimately went on to one of the most revered, purpose built diving watches of any manufacture, the PloProf:
Post war Omega was a dynamic and genius marketing firm, in that they made countless hybrid watch designs based on existing parts. They also mixed and matched dials, cases and complications, cleverly using tried and true model nomenclatures such as Speedmaster, Seamaster, etc.
The OP's Seamaster is a derivative of the Omega Ranchero dial...of which there are even "dress" variations, however this is widely acknowledged as the original (and best):
The Seamaster lineup enjoyed looking like everything from a Patek dress watch (namely those sporting "DeVille" dressier nomenclature)
to the stylish (and far more wearable than the PloProf) 300 diving watch.
It is in house branding at it's finest.
While the OP's watch is a beauty, with what appears to be an original dial with gorgeous patina, it really looks best worn casually and can be pulled off casual/dressy (as stated) with sportcoats, jeans etc. It would look peculiar but still cool with a fine suit, ridonkulous with formal wear....where a dress watch is appropriate.
(Not that I myself do not regularly mix these elements)
