Customer Reviews

Good build but rather complex to configure
The watch feels well build but the strap is a bit slim for such a nice watch.

The configuration is a nightmare. Firstly it will almost certainly need a few hours in the sun to get the functionality working.

Then setting the time and knowing what you are doing is very complex, as there is no digital concept, so it all revolves around the glyphs at the edge of the watch and bezzels. I would dread loosing the manual as it's vital to actually knowing what mode you are in. (Took me 2 1/2 to understand stand it).

But once it is configured, it just tells the time like any other watch, with an indefinate battery lifetime if exposed to light sources, and auto time updates that somehow work. I am stil not sure if it is updating the time though!!!!

The digital G-Shock are much easier to understand/configure.
