In my research about Rolex FAP ,I had lots of doubts especially about the all polished casebacks.
I Actually spoke toa person in Argentina who Bought sold and serviced them them in lots from the FAP in Peru.
.
Hé confirmed Rolex Daytona , Submariner ( i suppose he ment 1680) and 1500 model
However they polished lots of the FAP logo out , because it was hard to sell with Perú on the caseback .
.
One my biggest doubts was the polished casebacks on all the FAP Rolex .
.
Later their italian clients wanted FAP back on the casebacks . .. because the numbers where inside and FAP became fashionable .... They had to put the stamps back in . ... Argentina mid nineties to two thousand.
.
He told me , it is very difficult to fake the F.A.P stamp .
.
Hé also confirmed the gloryhole point and the numbers in the caseback .
.
When I asked about the stamp itself , original is pantograph stamped never to his knowledge acid etched , or drilled .
The discussion was about Fuerza Armada Chile having the same Caligraphy and why and showed him a picture , hé immediatly said that is fake , because it very difficult to make the correct panthograph stamp and no where near the same quality .
.
And was stamped in Peru and not by Rolex in Switserland .
.
And hé mentioned lots of Rolex FAP on the market is fake.
Now the challenge is finding the correct stamp.
Again my humble apologies
