i've bought one for a friend, ownner of a 1563 MH (and to see how it looks...)
it's a very nice aftermarket insert , aluminium made , fully black anodized and probably laser marked, typo seems to be exactly the same as the original.
no tritium , but silver triangle at 12 , it fits by snaping on.
be carefull , they are made for the first generation automatic autavias bezels (1163, 1563...) , not for those with tritium at 12 , but we tried it on a second beneration bezel too and it fits (some 3/10mm less than the original bezel) , but has to be glued on.

hope this will help you!

NB:the seller is very kind and answers all the questions
