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.

It is easy to navigate from mode to mode.

Color: Silver

I have only had this watch for four month. So far I am satisfied with its performance. One thing I like about it is that it only has three buttons. This makes it easier to manipulate. With only three buttons I have no problem remembering how to navigate from Mode to Mode.
