I am passionate geocachers and therefore traveling a lot and often outdoors. As it goes once through the water, in a cave or a tree, as it has other concerns and respects nature, no longer on a wristwatch. Nevertheless, the clock does not have any visible signs of wear after half a year. The closure has no single time inadvertently opened and button respond like the first day.
Power is supplied by the solar cell is awesome and the synchronization of the time works here without any problems in Vienna. In the first few weeks I checked whether the clock failed to receive a sufficient signal at night every morning, but that was only once in 2 weeks.
Although I got along for years with no watch and had to rely on cell phones and computers, I do not want to miss this gem. It does what I need, I just do not need to worry about it.
Thanks to Citizen that you build such things.
