pretty good watch
Color: Silver
Cheap but pretty tuff. No it isn't my old tried and true Timex but is does wear well and servives even at work. I pack a lot of material in my hands all day and no watch goes without scratching but this watch has taken it so far. No time loss and the date stays curent so no complaints from me about it.
