To recharge the watch you need to pop it out of the band and attach a special recharge dongle which plugs into USB port. I do this several time a week. So far no signs of the band stretching out. Time will tell how it holds up over time.
To latch the band with one hand I insert and tighten the tongue first and then push down on the tab. This watch is extremely light (0.8 oz) and it is waterproof.
