Luv the watch overall. But the dial is dark and sometimes difficult to read despite the light option.

This is a great watch with a touch of Royal Oak. Good for everyday use and also dressy. Watches Direct by far the most competitive sale price.
a great watch, however, i have no idea why casio always have issue with legibility
Love the watch. Arrived on time. Only issue is that the image displayed on this product page is wrong. Model number is correct though. It's gold colored not rose gold. And the dial is black.
Very solid build with some amazing features such as tough solar and Bluetooth. Gorgeous watch, even better in person
I love it so much, that I don’t want to scratch it. So I have stored it, so it stays new for a long time. Comes out on special occasion.. 😆
It's a real shame that the watch straps are NOT interchangeable... I would prefer this Gold watch to have a Black Leather strap with Gold stitching.... ALL Gold is a little to ' in your fave' IMO....
The all steel dark casioak moves more in the direction of good looks than absolute practicality for the following reasons; not so great legibility in poor lighting conditions, you'll need to use the lighting button to get a reading, ditto the digital display. But this is the stealthy version of the more blingy models and I was prepared for that compromise - very happy. The price at watch direct was the best for the oz market, so a great buy.
