Notes

Reference 6240, the first chronograph with screw-down pushers, was produced from 1965 to 1969 in stainless steel only and can be considered the forerunner to the 6262, 6263 and 6265 series of watches. This watch is illustrated in ?Rolex, Collecting Wristwatches?, by Osvaldo Patrizzi, 2001 Edition, p. 447.
