I ordered an extra link for my 3523.80 at the Omega boutique in Brisbane, Australia. My wrist was just a little too large for the bracelet it came with. It was 45 AUD and arrived in about a week. It was about half the price of the local watch guy and they mailed it (aussie post) to me without extra cost. I would go original Omega for that bracelet link as the ebay/other manufacturer may have some differences that would bother me. Almost like a real Omega with a fake bracelet. I brought the watch with me to get the right part and the watch repairer was very good to talk to. Super helpful. That is my take about adding a link to your bracelet. Good luck on sourcing your part, in case it is one that is not stocked by Omega.
