Hi...Thanks for looking.  You are looking at a New Casio Tough Solar Watch that I have "Modded" with

Strap Adapters to Except a Quality "Nato" Beautiful Green Strap. I also added a Quality Compass with Great Visibility that slides

Perfectly onto the Nato Strap. 

I tested the Accuracy of this Compass against an I-Phone Compass Today in the Woods and it was "Dead On"

The Compass did not seem to be effected by the Strap or The Watch in any way, so I was happy about that.

This Casio AQ-S810W  Modded Watch is the perfect blend of sporty and luxurious style. With a sleek Black Case,  and Arabic Numerals (Very Easy to Read), it's sure to catch everyone's eye. The watch features an Added Quality Compass , quartz movement powered by solar energy, and is water-resistant up to 100 meters. In addition to its impressive features, this watch has been Customized with a Unique Beautiful Green Custom NATO Strap. The Watch has a Tactical Military Look! The watch also includes a Backlight, alarm, day/date display, and chronograph function. This Casio AQ-S810W is the perfect choice for anyone looking for a high-quality, stylish watch that has been Customized/Modded with an Accurate Quality Compass and Quality NATO Strap.

I encourage you to watch the YouTube reviews on this Great Watch! Here is one from a guy named Green Craft.
