Need help with the meaning of AP's reference designation...
Does anyone know what the "BA" stands for in the reference number used by AP. I know a watch with "BA" is in Yellow Gold as "OR" (or rose) is rose gold and "ST" is stainless steel. Just no idea what the letters "BA" signifies in terms of being yellow gold?
Any ideas?
