Since these Mark XI watches were military issued, they were routinely sent in for service to keep them accurate, in good working order, and to keep up with ever changing regulations. As lume standards changed over the years, so did the Mark XI. Almost all original Mark XI dials were relumed as per the MoD. Around 1962, the same time most watch companies switched from radium to tritium luminescent material, the RAF required that there was a "T" in a circle on the dial to show that the lume was made of tritium.
