Hello Another very rare el primero and a many years old grail will be part of my collection soon, the Espada El Primero 01.0040.418, which is the same model as the Espada El Primero A7817 (manufactured from 1971 to early 1973) , with a triple date complication in moon phase. The only differences are as follows: the new logo was used on the dial and its back is plain (without star) with the model code 01.0040.418 and the mention "sub sea". Together with the 300 under ref. A7817, this means that a total of 800 Espada were manufactured. Watch very rare and for the advised connoisseur. This one is ultra full set Here are the photos of the seller, I will post mine as soon as it arrives Have a nice week end Sincerely Georges.
