Two. Both are Movado, and are actually the same style, but one is gold(tone) with a white face, and the other stainless steel with a black face. I wear the gold far more often, but when I wear silver jewelry, I pull out the stainless steel.
Both are bangle-style, and can be worn casually or with dressy attire. However, I once had a friend tell me that a lady doesn't wear a watch with formal attire because a lady should never be concerned with the time. As silly as this sounds, I actually do avoid wearing watches with formal attire (I just like the look better without a watch).
