Nice watch! It is plastic like but it is solar. No indiglo button only a little luminous on the hands so you don't want to wear it in tje dark and expect to check the time. 45mm case is good size for my wrist and the band works good also, Not too long not too short. Overall a good watch with no problems

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.
