Identifying the age of a newer Rolex

[padi56]

No matter the serial when properly serviced Rolex watches in general will in many cases outlast their owners.Rolex watches are not like loaves of bread or packets of sausages they dont go off .The most important thing is first condition second the price anyone is willing to pay.Fact you could never tell when any Rolex was made, only a approx date between X&Y years when the case or clasp was stamped.And most all serials overlapped a year or so, now how old the movement inside the case well that could be weeks, months,or years old before they are matched to a case.Rolex sends many hundreds down the COSC to be tested they test so many Rolex has there own machine there.After test sent back to Rolex passed and failed, then stored with movement like the cal 3135 perhaps thousands sat in store till needed for production.
