Granted that all good diver watches must have a unidirectional bezel. Granted that all good diver watches should have a luminous pip/pearl/marker at the 12 o'clock central. But for Tudor Pelagos, you could reset of the bezel pip back to 12 o'clock in complete darkness or with your eyes closed, as there would be a slight pressure resistance when the bezel goes a full circle. I tried that on Rollies, Seikos, etc and have yet to find the same feature on their diver watches.
It was also a tell-tale sign for people in the know to separate the genuine Pelagos from the replicas, as the replicas were replicated closely to the genuine yet were unable to have this feature. I've seen a replica being sold on Mdh (marketed as genuine), where the seller was letting go below the normal market price as he informed that his "genuine" watch was missing the box and papers and from checking, it really did look pretty close to the actual item (which I owned), but the bezel turn was simply like a normal diver watch. When I explained to the seller, only then did he revealed that he bought it very cheap but thought it was real, as he had previously compared it to an actual item in an AD. So beware of unscrupulous sellers selling replicas on Mdh sometimes...
