Enclosure and Wristband for FitBit Force electronics

This is a replacment enclosure for the FitBit Force I have. I needed to open the device since the LiPo battery seemed to have died (it turned out that water found its way into the "sports" smartwatch (what did they think when they designed a fitness tracker which isn't waterproof???!)). Since opening this device means breaking it, I needed an new encolosure for the electronics.
Also I'm still trying to figure out how to make the charger connection, the opening to access the pins is there, but the original charger connection is molded into the metal part of the old housing and therefore its not likely that I'll get it out in one piece (besides the fact that it needs the metal housing as a mechanical clip). Thinking of using a 2 mm spaced female header with some two component glue soldered to the board with small wires.
