Fit in pocket
Color: Dark Gray, Style: Classic
Bought as a gift. My husband really liked it, held all his cards. The leather was very nice. Color was very soft gray and I liked it better than the normal black or brown. Wallet fit well into his back pocket.

Great Wonderful!!
Color: 6617：Blue Dial and Gold Silver Strap
I've now purchased about 3 of OLEVS watches.. The fit great.. Band is so easy to ajust. I'm super careful. So I took great care and time on the first OLEVS watch. So it took me about 15 mins. Now about 6 from start to finish.. Don't hesitate due to fitting the band. You get to custom fit it to you. And it's easy...real easy. Best of all. You get to keep the adjusting tool they provide...
