The ceramic surface gives this RM 55 a brighter perimeter than the carbon versions, while the blue strap prevents the presentation from becoming uniform. That balance is the reason to choose it: the case reads cleanly in a side profile, but the strap still gives the watch a recognizable color cue. Three-quarter photographs should preserve both effects at once.
When reviewing the gallery, look for consistent ceramic edges, a level bezel and a clean crystal boundary before turning to the blue strap. The strongest configuration is the one where the case, openworked dial and strap remain visually coherent from front to back.
Use the side view to judge whether the bright case remains even around its corners, then return to the front image to assess the blue accent against the openworked center. The two views answer different questions and together prevent the strap color from hiding a case or bezel issue.
For a buyer choosing between ceramic straps, this page owns the light-case, blue-perimeter combination. The white-strap version is calmer; the carbon versions are darker. Keep that comparison practical by checking the same attachment points and crystal edge on every candidate.
