二手rolex上行驗錶有咩要注意??

Hi,
1)驗錶要幾錢到(隻錶係 16570 Explorer II)?驗錶有d咩重點要注意?
It depends. Go to a bigger center like RSC , but
I have no idea if there are any in HK.
Rolex elected to start numbering with a letter prefix (e.g. ... In 1994, Rolex started yet another sequence with the letters: W, T and U, then A, P, and K in subsequent years.

Your Rolex watch was made in Jan , 2000 .

Hope it helps.
Bye bye
