There is really no way to determine the value of a Rolex without seeing it, opening the case, reviewing the serial number (either numerical, Roman Numeral plus two digit year, or a letter preceeding a number). Also, what type of Rolex model is the watch? I will tell you that when I was in a jewelry store in London the owner admired my 1950's vintage Rolex and offered to swap me for any Rolex in his display case (except the President model). Most of the President models retail for around $16,000 up to about $32K.
The letters in the model number designate the year model, when compared to a model / year guide.
1908

The year is 1992 -the "en" in the model number identifies the year.
Johnson outboard model number J175EXARG, would be a 1994 year model.
A 4 hp Johnson outboard, model number J4REIA, is a 1991 year model.
You listed a serial number, not a model number.
No such model number in the Winchester line.
A 175 hp Johnson outboard, model number J175TXCSA, would be a 1980 year model.
