Thanks everyone for the answers. The bezel, excluding the numbers with the liquid metal, looks very beautiful (it is also ceramic, correct?). If the bracelet is also very well made it seems very difficult to distinguish it from a gen (except for the light reflections on the numbers of the bezel), I have seen a Seamaster 300 up close only once and I don't think I would be able to distinguish it so easily. I had read a few posts before a "problem" is also that the lumen is inserted under the dial on the rep while the gen lumen is filled in the cutout and not inserted as the representative ". I was not able to understand what it means. I see this difference. I am still undecided between the Aqua Terra black dial and this Seamaster 300 specter, for this reason I have many doubts and questions.
