I was hesitant about this watch, but it's about 20X more than what I imagined..........the spring bracelt/band is VERY comfortable and the watch never comes loose........i have an 8.25" wrist and it fits very well, plenty of room for larger wrists too.  Just the industrial look of this skeletonized mechanical with the band is unreal.  First day wearing it, a woman made a comment about how great it looks and she never seen anything like it....(from a sales lady who sees thousands of customers a day in a high traffic tourist area).......  Great job Android!!!
