Renewed my PMP Certification and decided to treat me with the grail: the AQ4020-54y (Thank you Seiya-san). I will post some picture later but before I would like to resize the bracelet, and I confess I do not know how to separate the links: The pin has screw like threads in both sides. I tried to unscrew in one side but that only make it just to spin completely including in the other side. Then I tried to block on side and to try to unscrew but then it does not move. I do not know if a jeweller knows this system. Could someone please advise in this matter?
Thanks and regards,
UPDATE: This may be useful for someone in the future. Again Seiya-san came to the rescue. Very difficult to do by oneself so my daughter assisted:
