3) Look over the bezels for the five models that appear. GWA-1100R-4A is the orange bezel, then they have four black ones listed with (apparently) differently colored detail painting. Figure out which model's black bezel you want, since all should be physically interchangeable.
4) Go to UK-based Casio Watches - Tiktox -- they can get any parts from Casio that PacParts can, and offer free shipping within the UK. If they don't have a part listed (and I didn't see any bezels for the GWA-1100) call them at the number listed and they can almost surely get them!
