·I was polishing my Seamaster Planet Ocean's sapphire and display back this evening. I held the watch between my forefinger and thumb and used a polishing cloth to clean the front and back of the watch simultaneously. I noticed that the sapphire seems to rock slightly, with a noticeable "click" as I pushed it down towards the edges, close to the bezel. Is this normal? I would have expected the sapphire to be solidly fixed to the case and there to be zero movement at all. Am I mistaken?
