Here's a vintage Patek Philippe manual wind tank in 18k yellow gold with a beautiful black onyx dial from the early 70s. Keeps great time and is fully functional. Measurements include a 28x38mm case and a 18mm lug width. On its original Patek black alligator leather strap (buckle seems replaced). Time only. Gold dauphine hands. Clean black dial. Hallmark is on the caseback. Stepped bezel (multi-layer). Black cabochon crown Both the dial and crystal are free from any scratches or marks. Hard to find these obscure examples with these multi-stepped cases. All parts are original including the crown, caseback, dial, and movement. Both the dial and case are in great cosmetic, untouched condition.
