Hi all! Just ordered the AW Series 3 Sports in Space Grey. Just have a couple of doubts: while the Series 2 had a cermaic back, with the Series 3, Sport line returned to the composite bac, so I wonder, how sratchable this back would be, teling you antecipatley I am very careful with my gadgets? I, by no means, will be putting it down on a surfec that could scratch it easily, aside being careful enought to clean any dust on the charging base prior to putting it to charge. Being enough careful, will this AW remain presentable for a long time? Othe question, now regarding the charging base: is the surface that contacts the back of the watch rubberized or made with some kind of gentle material?
