The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a hand-winding movement, calibre 10FL, which is working nicely. The movement is fully signed with the Wittnauer name.
The case is 10k gold filled with a stainless steel case back, and it is all in very nice condition with just some light surface marks to the back.

The lens has light marks if you look closely.
The signed dial is in its original finish. There is a little marking but not too detrimental.
A new leather strap has been fitted.
The watch comes in a vintage Longines Wittnauer presentation box.

In 1950 Longines bought Wittnauer and marketed some very similar lines of watches under both brand names whilst maintaining separate factories. This collaboration continued for 125 years until Swatch took over Longines distribution in 1995.
