From the time I bought my 245 replacing the 235, I noticed that the buttons are very hard to press, produce a very strong "click" sound, they seem to have two levels of pressing, and also the pressing is inconsistent: sometimes it is clicky, sometimes not. In comparison to my old 235, they feel very bad and the quality seems worse. Maybe it has to do with the mechanism for the water ressistance, but still, the feeling is very bad: the watch feels cheap because of that.
Did you notice the same in your device?
