HS9 Series 1, obtained from its original owner, an RN Fleet Air Arm pilot. He and the watch went into the drink during the Falklands. Happily, they both came out running strong!
Just in. 1948 IWC Mk11 with correct non-Inca movement. Complemented with a custom fixed bar strap from Matteo Torre (torrestraps).
A beauty! IWC is a brand I have never owned, but if I were going to have one example, and I may some day, this reference would be it.
