920 has had the strap replaced once but is otherwise in good condition and latest firmware. $110 shipped to anywhere in CONUS. Includes charger.

1 735 is from Thanksgiving 2018 ( I bought for me); the other is from Christmas that year (my wife bought for me). Both lightly used as I decided I prefer the 920 display and interface. As I won't be running until November due to foot surgery, my loss might as well be your gain. 735s are $150 each, shipped to anywhere in CONUS. Both include a charger.

Pics on request.
