I read they are value I bought this one for 15$ number on the back is 6393 p with I think is 1986 and the p means it was given to an employee. Anyone have any idea what I should sell it for on eBay??
First number=Year of manufacture, Second and third numbers=Week of manufacture, Fourth number=Day of manufacture.
This code is often followed by a letter P. This simply indicates that the watch was made in Gretchen on the main production line near Biel.
Don.....
PS: Some watches are stamped with the letter P.The letter P ( not to be confused with the one following the date code) means that the watch was sold to a member of staff working in the factories (Personal edition).
That's a very nice swatch for $15 . I believe it is called a "skeleton swatch " so u might try that search term . I have a wristwatch book that has a couple dozen Swatches in it , but it doesn't have that one , some go for $100's to $1000's
Good Luck !!
