Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.

Great material. Sadly no pocket
The fit is not tailored. So if you are slim around the waist it will feel baggy. But enough material to tuck in or go around a large waist. The material is not stiff. Wash and dried on warm. This has been worn 2 times. If you take it out of dryer and hang up, the wrinkles come right out! The only drawback: No pocket. My wife didn't notice when she ordered, we threw package away otherwise would return, because it was a little pricey. But nice clean look!
