it is a discounted rep...no longer available by the dealers with the ETA2892A2 mvt + soprod 9040 module...when it was available it was in the 600USD range...now they go (when they appear) on the 2nd hand market from 1000-1500USD based on the mods done (lume,gen crown,DW, cyclops,...)...
there is a version with the asian 21j mvt that is available for 100+$...however this one is not as accurate as the more expensive one!
I have the 027 with the ETA mvt and I can say it is one of my fav PAM's...This year I have in plan to PVD coat it and to add the 028 dial (which I have a spare one) and finally to transform it to a PAM028...
I wish you good luck in sourcing one!
