This a 3d printted mod case for your 14mm Pebble Time Round smartwatch. It allows you to (1) use a 22mm watch band and (2) apply a seiko bezel insert (outer diameter of 37.5 mm. you can find it from amazon). It comes with two parts: the case and 4 buttons. You have to order the buttons from my shop.
PUTTING THEM TOGETHER IS SIMPLE. insert the buttons first and then push your watch into the case. The case will secure the watch in place. No glue is needed and the process is reversable.
