Examine the Rolex print under magnification and you will find that a genuine Rolex is superb and has a convex appearance with no bubbling and sharp corners. Fakes often exhibit bubbles and less defined edges. This includes the date magnified by the bubble.
Rolex Second Hands move smoothly without jerks. A jerky motion indicates an internal Quartz movement, and the only Rolex with a Quartz movement is an Oyster Quartz, therefore all other models should be display a smooth motion. The smooth movement comes from the 5 - 6 ticks a second of a Rolex, unless its one of the mechanical 1960s model or of course the OysterQuartz.
A Rolex date movement is sharp and occurs on the stroke of midnight without lag.
Rolex movements have different coloured wheels and rotor. Fakes often do not go this far and movements are stamped ETA.
Rolex always number the head fixing bracelet end pieces and edges of the bracelets are always smoothed. Fakes do not have this attention to qualty.
Rolex engraved numbering has a continuous smooth and crisp movement throughout each number or letter. Fakes exhibit evidence of multiple starts and stops under magnification.
Engraved between the case lugs at the 12 oclock position. This 4, 5 or 6 digit number refers to the model which should correspond to the model of the watch.

If you can open it up to see inside and if the seller does not allow this it is very likely to be a fake and they know what your decision will be if they do.
Feel all edges for smoothness both inside and outside, as Rolex pay particular attention to chamfering and smoothing everything including the screw heads.
Often overlooked are the boxes themselves, these are very expensive items and the box should reflect this attention to detail.
Update 24th Oct: However, as it was recently pointed out to me by a reader of this guide, few people will risk opening up a £4000 watch even if it is genuine. The way round this would be to consider reputable jewellers photographs or authentication. A good practice for the sellers to adopt as well, as the item would be taken much more seriously.
Update 29th Oct: After a recent message from another eBayer, I have to add that a genuine Rolex is not co-branded and Rolex do not print anything other then ROLEX on their recent watch models. Athough early watch models bore the name of retailers, and as such are highly collectable, Rolex never double-namded their products with Disney or anyother other manufacturers of any products. If you are in possession of any of these watches then these are replicas, and a recent writ has been issued by Rolex for the use of the trademark name.
Although this is sound advice, the less experienced of us should finally seek expert advise for verification.
