Do not buy
Color: Green/Black
Do not buy. When I received the watch it did not work and the battery was dead. I bought a new battery and it killed that one as well after about a month.

Inexpensive doesn’t mean cheap.
Color: Black/Orange
After 10 months, zero complaints. Well, I got rid of the horrible NATO strap 🙄. That’s a personal preference. Easy to swap out to whatever you like. Keeps accurate time meaning it’s the same time. I’m not micro analyzing it and the seconds gained/lost. It has a confident look and feel and makes you feel good when wearing it. Sure it’s not high priced but it’s not cheap. Very comfortable, light and not unincumbered. If this is what you’re looking at, you’d be satisfied. Great looking, durable and simple watch. Full confidence.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

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.
