This watch is a complete disappointment. Right out from the box, I adjusted the time per the instruction manual. After finshing adjusting the watch, I pushed the crown in (two clicks). The second hand started movement after almost 10 seconds. From then on, the second hand was stopping and going by itself. Within less than anhour, the watch was behind almost 25 seconds. It is a piece of junk. I would not advise anyone to buy this watch.

Rough dial, pretty watch

Color: Mesh Strap watch balck

Great looking watch, the dial is rough on the skin, it should be refined some to not have sharp edges.
