I have not had this watch very long, but have been impressed with it so far.

It has no problem locking on to the signal from the atomic clock at Fort Collins even though I am in the eastern mountain range.  So far it has locked on every night first try even with me wearing it which is a good thing since I tend to wear my watches 24/7.

Some reviewers talked about buttons that where hard or impossible to push, but that has not been my experience.  Yea they may be a little harder to push than some watches, but remain very usable!

The solar cell is keeping the watch charged at the high level of charge even with use of the alarm and light.

I guess the only negative I could say about this watch is that the keeper for the band slides around somewhat allowing the end of the to pop free on occasion.
