The watch is a little on the light side, guess that's because the case is mostly plastic and the safety clasp is cheap but will last. I love the auto illumination feature which lights up the face when the watch is angled towards you. Gets the atomic time with no problem as long as it is near a window. No complaints, I wear this thing all the time now.
In the future, I will only buy solar watches. This is my second one and the first with the atomic time receiver.
I love the fact that it sets itself and you never have to replace the batteries.
Cons: Its pretty thick on my wrist.
Still worth every penny I paid for it.
If you are a hiker, you may think, as I thought, that it would be a great feature to get a quick bearing without a compass. There's a straight-forward but non-trivial calculation to get the solar azimuth given the time of day and latitude and longitude. From the description of the watch, you would expect it to do that calculation.
However, it appears that the watch does _not_ do that calculation. It produces a linear result which is much too simple, and is off by nearly 40 degrees at certain times of day. It appears to get the azimuth closest near sunrise and sunset and noon, and is off most of the rest of the day.
I was quite disappointed when I found this out. If you never plan to use the solar bearing, you won't care a whit.
[Fortunately, I decided to test it out before hiking without a compass, and I happened to do it at a time that showed up the error very well.]
Here is an example, for a particular day, of the azimuth according to the watch and the correct azimuth from the US Naval Observatory, so you can see what I mean:
(Sorry, I can't format this properly. The last number on each line tells you the error.)

The main reason I purchased a watch with a metal band is that I have had so many of the plastic/resin bands break and the replacements cost almost as much as a new watch. This one seems durable although the band is connected to the body of the watch with plastic/resin. Hopefully those parts will not become brittle and break.
**The body of the watch is plastic even though it looks like metal.**
As other people have mentioned, upon receipt the watch may take a few days to get up to full charge.
Overall, after 11 months, I'm still satisfied with the watch and glad I bought it.
To aid in band size adjustment, I will try to post pictures of some links and the pin assembly and the tools I used to remove the pins. In the pictures, the pin/sleeve assembly is positioned next to the link in the same orientation as when installed in a link. The point of the safety-pin is used to push the small end of the link-pin out of the tiny compression sleeve in the direction of the arrows on the links. Do the work in an area where you can keep track of the tiny parts and find them if you drop them. Use two large paper clips to push the pin and sleeve together when connecting the links.
Another option is to buy a link pin removal tool (Amazon has them).
If you're not good with tiny parts, get a professional to do it.
