Fantastic guide, thank you! On reassembling I did find I had trouble getting the watch movement back in the case. This was because the buttons were catching on the button arms. To solve it I used a flat head to push the buttons out, from the inside, as far as they would go and with a bit of persuassion it all went back in. Thanks again :-)
