In the 1960s', 70's and up through the mid 80's most dealers couldn't give away Daytonas. In 1984 it also seemed the Sub and GMT were the top of the line SS watches as they had MSRPs of around $1,350 and a Daytona was only $1,100. Daytonas were often sold at very large discounts. The original Daytonas were manual wind and the steel models were not certified chronometers. Those were 2 issues that back in the day hurt its sales as most people thought of Rolex as being synonomous with automatic movements and some people thought a certified chronometer means more than it does today. Many people say the Italian collectors were the first to start to become interested in manual wind Daytonas. Some people have said it was the result of people seeing Paul Newman wearing a manual wind Daytona, in a film. Not sure how true that is as I've never seen footage of him wearing one in a film, although there are several pix of Mr. Newman wearing different Daytonas over the years in his personal life and as a race car driver. In any event, I think the second generation Daytona, which had an automatic movement truly changed the Daytona market and it quickly became one of the most sought after watches. Rolex also increased its price beyond that of Subs and GMTs. When I first became interested in the early 90s they had a list price of around $3,850 (Subs and GMTs were around $2,850). Supply seemed very limited as they were only getting a limited number of movements from Zenith, and they seemed to prefer to put them in the newly released two tone models, or the all gold models since the profit margin was much higher on those pieces. I believe the shortage of the then new automatic Daytona caused people to go back and buy manual wind models, which eventually surpassed the value of the automatic watches. The market on Daytonas definitely became softer with the economy colapsing around 2008 and prices of SS Daytonas hitting $9,500.
