Watch has 14K (jeweler tested – see last picture) Gold Cap over stainless steel 35mm case (harder to find) and has the 28.5 R-21 Movement with 17 jewels. Oscillating weight is its original and engraved “Submarine” – see pictures 2-4. Watch shows some use and age wear with some scratching on case and crystal and probably needs new crown and stem also some specking/age on dial.
