Excellent Casio watch, very light on the wrist, very high quality and beautiful, with 5 bar water resistance, and synchronization with the atomic clock for accurate time. In Athens where I live, it synchronizes during the night hours, and I mention this for the friend from Crete. In a word, it is worth its money to the fullest

Beautiful watch, it is an old series from Casio that has been re-released. I would have liked it to be in a more robust construction version. Nevertheless, it is very comfortable on the wrist, as if you are not wearing it at all, definitely suitable for everyday use, but it is also beautiful for going out. It is very fragile to scratches and requires a lot of care. The time is displayed very clearly, the date also shows the day first and then the month, unlike other watches that show the month first and then the day. Of course, you can adjust it if you want it to show the month first and then the day. It can synchronize the time/date with the antenna that the watch itself has. It does this automatically, but you can do it manually whenever you want. It is preferable to set it to manual mode to make the battery last longer.
It supports five protocols, one for each continent basically. For Europe, it supports the protocol that communicates with an antenna in Germany. Specifically, the DCF77. Unfortunately, it didn't catch for me at all; I haven't tried many times, but searching on the internet, I found that the range of this antenna located in Germany does not reach Crete where I live, as it exceeds 2000 km distance from the antenna. The mentioned coverage map is attached in the photo. Since I will be outside of Crete in a few weeks, I will try to see if it synchronizes and will update my comment. I should mention that I tried to synchronize outside the house to avoid obstacles, and at night as suggested. For now, it seems that the problem is geographical/range-related.
