This black dialled 19ASD just went for $1920 (before 20% buyers's premium) at this morning's Auctionata listing. https://auctionata.com/intl/o/110670/longines-conquest-switzerland-c-1956?search=longines&cat=shop Apart from the nicely patinated original dial and original crown, the case looks polished and there's no enamel on the caseback medallion. Someone really went all "ashleyed" out on this one! @LouS, you'll probably make a fortune if you listed your pristine 19AS!
According to my internet translator, that watch is "not working, needs service". Not sure what would be wrong with it. Just be careful, gatorcpa
this GMT coke is also fully overprice... https://auctionata.de/o/109870/rolex-gmt-master-ii-ref-16710-schweiz-um-2000 please consider 25% premium and no box and papers!
