Before you adhesive everything back together, now is a good time to test that everything works as it should, and that your Pebble boots/vibrates etc. You can also see me reusing photos here, since I wasn't planning on making this guide when I replaced the battery in my watch - this just sort of happened later!

Also, installing that LCD Ribbon cable is a pain. Be prepared for that, and take your time as always. Use a spudger to press down and seat the connector. I found it easier to get the connector seated by moving the display to the right (2nd photo), and you can also get a side on view of the connector to check if the pins are lining up as well.

If you haven't got a plastic spudger, I'd highly recommend you grab one and use it to press down on the connector to seat it, otherwise you can damage the connectors (I've done it before, learned the hard way).
