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.

Don't waste your money.
Color: Silver
Don't waste your money and time on this piece of junk. The clasp on the band would not secure the watch to my wrist and you could not adjust the clasp. Watch kept falling off my wrist. I guess the price on the watch should indicate the cheapness.
