Nautilus ref. 3700 - HOW TO n. 9 - A secret revealed
HOW TO n. 9 - A secret revealed -
Serial numbers matching between case back and bezel.
This is a little secret that we're going to reveal.
The last three numbers of the case serial number must match with the three numbers punched on the back of the bezel.
This is of course quite important to evaluate the originality and correctness of the bezel itself, understanding if the parts were born together in that watch. This is a "virtuoso" performance which only Patek and a few others Maisons can afford - given the limited numbers of production.
And now, let's all go to open and check it
