My first Rolex was a 14060 4 lines and the second, a 16610 M serial.
A lot of fantastic input in this subject !
With the experience, a 124060, the real Sub.
There is a Sub and, after, a Sub Date. And like friend said, the DJ, DD, GMT, YM, SKY, ect has date. So you have all the leisure to have a Rolex with date complication.
