Ive had two versions of this watch, the leather strap version and this metal version. The only weak point on my old watch was the leather strap. This thing is simple, elegant, and practical, couldn't really ask more from a watch. It holds up pretty well and doesn't scratch too easily (if you have a labor intensive job you might want a glass protector). I've had mine for a couple months now and it only has a few very faint scratches but that's just because im rough on my watches lol. I would recommend this to literally anybody

A great buy

Great value! It was listed at such a low price that I expected it to be a piece of junk, but I was wrong. It's a fine watch that really should sell for more than I paid. It looks and feels like a much more expensive watch, keeps good time, and has an easily-adjustable stainless steel band.

Great budget fancy looking watch

Looks like a fancy watch from afar with none of the associated cost or maintenance. Exactly what I wanted. However the crown is kind of exposed and flimsy looking, so be careful to not get it caught on anything. Adjusting the band length is kind of fiddly, give yourself some time and good lighting to work on it. Also the connections are kind of flimsy so don't expect to be running around in the jungle with this thing.

Band included is for a fat wrist.

Surprisingly good quality for the price. Hard to read in dim light. If it lasts I'd buy it again.
