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.
