This is the steel 1930s rectangular dive watch with the 2-pc, slide-out case. Please offer what you have or forward any leads to available pieces if you've seen something out there in the wild.

Thanks - Bill (Squinky)

 

Are you looking for some specific parts? Spare parts for the 19.4 caliber are not so difficult to find. Other parts specific to this ref (case, dial, hands), well...

 

Omega Marine CK 679 case parts, dials & hands - abandoned project watches, etc - yes, I already have many 19.4 movement parts and donor movements are pretty easy to source - thanks!
