Good, inexpensive work watch
Color: all black watch
Bought as a working watch so I don’t wreck my good watches. It’s been working just fine and holding up well while not taking very good care of it. Keeps accurate time. Glass has stayed clear. Black finish looks good and is holding up well. Seems to hold up with steady pounding. Stop watch buttons are a bit crude and will mess up your time when your hand gets pushed back against it during hard labor. However, I have not babied this watch at all.

Color: all black watch
It’s not an ugly watch, but I did not think the watch looked as nice in person This watch lost several minutes over a few months. It is light and feels cheap. However, it was not expensive, it’s comfortable to wear and beauty is in the eye of the beholder.
