bracelet adjustment

Recently picked this up and honestly have no need for it. Hoping someone out there can make use of it. Still in excellent condition. Please let me know if you have any questions. Looking for $350 shipped in the US.

Hello guys can u please advise me what tools are needed and how are the links of the bracelet of MM removed in order to be adjusted? is it something i can do by my own or should i leave an expert do this? Thanks
