Im new to the forum so may have posted the same question the wrong location earlier. so forgive me if you see it for the second time.
I have just this week bought a new Rolex Date Just 41mm. When i measure the diameter of the watch with my ruler, it measures 39mm. clearly this is not a great way of measuring the diameter of a watch but i cant see how it can be out be 2mm. Can someone help or advise please?
