I recently purchased this charging station which had an area to charge an Apple watch:

I wanted it to work with my pebble time, so I designed this adapter for it. You can see a video for it here:

There may be other bamboo charging stations available with a similar watch area with the round hole interface like the one here. Also, you could print this without the round peg on the back side and glue just the square portion to almost any other stand.

And don't mess with the cheap chinese charging cables as a replacement for the official ones from Pebble - they are complete garbage.
