1. Rolex watches are fitted with a sapphire crystal (the glass face
of the watch) that can only be scratched with a diamond.
2. The ‘cyclops’ date window in a real version is dead centred above the number.
3. The quality of the printing on the dial should be perfect, with indicators and type evenly spaced and no fuzzy edges.
4. The genuine Rolex movement sweeps smoothly round at about 28,800 revs per hour – each second is broken down into eight steps. Even when a fake uses a Swiss-made movement, the second hand’s ticking is usually visibly jerky.
5. Over where ‘Swiss made’ appears, the brand’s logo is
laser-etched into the crystal. In a genuine Rolex, this is made
up of hundreds of dots set at different heights throughout the crystal
(so it doesn’t create a weakness in the glass) and as such is barely visible – to see it clearly you have to look through a loupe (the small magnifying glass used by jewellers and watchmakers).
6. If you remove a Rolex bracelet you should find the watch’s case number and model number engraved on the side at six o’clock and 12 o’clock .
