Hi Mahesh,

Thanks for your help but I am fluent in French as my wife is French 😂😂. "BA" does not stand for boitier acier which means steel case as "BA" is used for their Yellow Gold watches 🤷‍♂️

Need help with the meaning of AP's reference designation...

By: holdemchamp1225 : August 10th, 2019-05:00

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...

bad guess

Boite Acier = steel case but you say it is yellow gold !

Breguet uses BA for yellow gold, BR for rose gold, and BB for white gold, with the later two being understandable [nt]

www.r-l-x.de "We kindly inform you that material code "BA" for the timepieces in 18-carat yellow gold has no meaning. Should you require any further information, please feel free to contact us at your convenience. Kind regards, Carlos Audemars Pig...

Thanks Ron...

Strange that the code BA has no meaning whereas the other codes seem to be logical 🤷‍♂️👍

Thanks for the answer, Ron

But that was a really anti-climatic end to this thread, LOL!
