This watch has lasted years through many, many trips into a hot spa pool.  Never even noticed it had a date function, but these never seem to work right--so the smaller the better--can't even see it.  The band is the only problem, and there are not any on Amazon that are good replacements.  Its 16 mm. and I just ordered a one-piece replacement that is women's 12-16 mm. in black velcro.  The only other band was a fusha one for $30 (too much) (in nylon).  Leather is fine if you are not getting it wet.  I'm the only one who has shown up in the spa with a watch on consistently.  The band is very funky.  My band never was nice looking, looking dirty even after many trips to the pool where it got actually very clean.  However, the watch was always comfortable, although stiff.  I wore it until the little gizmo that holds the band end in broke.
