You need to bring it to a watch jeweler to have it resized (just like a Rolex or Pebble Steel :)
Those shopping mall kiosks that offer watch battery/band change would be able to help as well.
We are looking into providing a DIY watch band resizing tool as a stretch goal.
Based on the feedback we have received so far, we have decided to keep the exterior look of the watch band clean of any logos and move any visible logos to the inside of the watch band. In other words, no product logo will be visible while you are wearing the watch.
