Why do you need the parts number, there's only one moonshine bracelet, your AD/OB will know what you want.
Hi,
You are right, the OB will know which Moonshinegold bracelet to order if they know which watch you own, but there are two different Moonshinegold bracelets produced: one full brushed with the Apollo 11 50th LE and the other that fits to the Panda and Greendial Speedys. They are not interchangeable as RJB from fratellow stated.
