I'm just a maniac who likes to have his watch exactly like it was when sold for the first time.

This is called in finance PIT for Point in Time, the ability to get an information exactly as it was the day and year it was first released.

: I'm fairly sure TH no longer have MH Bezels for this type and they
: would want to service the watch anyway, so would cost a lot! I
: believe this watch has been to them recently anyway and they
: probably fitted the Tachy Bezel??

: My view would be to enjoy it as it is while it is perfect, many
: Autavias now wear different inserts (as do some of mine) and i
: see no problem with that. See what anyone else thinks.......
