first post of long time lurker. For christmas I got a GW-056 which I have been very happy with. I live in Trondheim, Norway and I think this is quite close to the borderline for atomic synch shown on the maps from Casio. However, when I have put the watch close to a window facing south, it has synched almost every night since December, until a few weeks ago. Now it synchs perhaps once a week and I was wondering if this related to the early sunrise in Trondheim at summer. When it is DST, the watch automatic synchs at 03.00 and this is approximately the same time as the sun rises (sunrise at 02.59 and sunset at 23.41 today). If the watch fails to synch it will try again the next night at 01:00 and lately it seems that the watch synchs more easily at 01.00 than at 03.00, perhaps because it is then still two hours to sunrise?
Could the synch problems be due to the position of the sun or is this just coincidental and there are some other atmospheric conditions that influence the reception? Or is my watch just getting tired?
