That's a beautiful watch and looks very similar to the ref 2867. As ConElPueblo mentioned in the other thread you must get a new tension ring. A new crystal with part no. 063PZ5202 would fit the 2867 so it might be also compatible with your watch. A lot more dial real estate is going to be uncovered! Edit: The difference to the 2867 is of course that the latter is with date. Size-wise they are the same.
Congratulations, that is a beautiful watch (as are your others as well), and a fantastic story to boot. Well played Sir.
Good news indeed, but I find it such a shame that the first thing one reads is the enormous disclaimer at the top of the page! Talk about putting a downer on it
