hey guys, i need some help with the casing of Audemars Piguet cal 2121. I have the movement and the dial of AP cal 2121, but i don't have the case for it. Can anyone help me to find the case for the movement? or tell me where i can buy the case (generic case is okay with me). i really don't know where to find the case, and an original one would cost me a lot and i'm trying to find a cheap alternative. thx a lot.
