I haven't read the entire thread. But the mid case on the OP watch is not correct for a 145.022-69

Here we go with the "original" ref. 1067 bracelet with 516 end links back from restoration:

@ortope I have just made a detour to the address listed on your guarantee (St Médart en Jalles) because I had a little doubt.
that's what I thought, that's the address of the Ariane Espace rocket fuel test center.
Did the original owner have company accommodation there at the very beginning of the founding of the group ?
it also explains the address of the jeweler in Toulouse, another city with important Aerospace industries.
your watch would then be directly linked to the space adventure.

do you know the history of your watch to confirm or not this hypothesis?
