Hi all
As promised here are more pictures of my 5402ST Serial A-3x.
I purchased it indirectly from the first owner, a gentleman from Berne / Switzerland. It was at the AP workshop for a movement overhaul. They also did an incredible job in giving edges, shine and matte surfaces back to the case (see two pictures below "before" and "after"). Dial, hands etc. original and un-touched. And the cream on the cake from stay at the AP spa is the very nice Certificate of Authenticity confirming the correct movement number for the case.
This one will spend - for obvious reasons - quite some time in the bank safe, but my A-81x and my black A-12xx "Karl" get a bit more airtime.
Enjoy
