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.

Thumbs up!
Color: Stainless Steel/Blue/Stainless Steel/red-blue
Amazing watch with fabulous details for any Snoopy fan. Very slim profile for an automatic watch. Colors pop. I wear this watch in the shower and swimming and it's water resistance is on point. The watch also has light-charge lume, which is a wonderful detail. I own several Peanuts x Timex, but this is easily my favorite.

Beautiful Retro Inspired Automatic watch.
Color: Stainless Steel/Black/Stainless Steel/Red Black
First I'd like to start by addressing one of the other reviews. This is an automatic watch so it is wound by motion but it also can be hand wound via the crown. The myota movement (citizen) is rated for about 40 hours fully wound so if used properly and worn daily (and if set correctly) it should run throughout the night and still be the correct time and date when you are ready to put on in the morning. This watch band style is one that isn't used very much any more and requires a screwdriver or tool to open the wedge on the lower latch to move it to the correct place on the band. This is easier to size than most metal watch bands and is much more flexible. Once you set it to your wrist size it shouldn't fall off and the adjustment shouldn't move unless it isn't set properly. It has a latching mechanism that should snap together and hold tight. It can be hard to get used to putting on at first but after a few times you will know how to easily put it on. I've owned a watch band of this style previously on a watch I wore daily so it was okay for me. I'd say that anyone looking at an automatic watch is probably more of a watch enthusiast and already knows the little nuances of owning one. If you are new to watches do your research first. Otherwise if you want something a little easier get the Timex Q version of this. It comes with a battery powered quartz movement, while it ticks a bit loudly, is a little easier to live with if you aren't accustomed to automatic watches. This is a beautiful Retro Inspired watch, I got it while it was on sale for 120 and it's a steal at that price.
