Looking for some help locating some additional links for my Longines Gold Medal wrist watch, to fit my wrist.

I have contacted Longines Service Center in New Jersey and in Switzerland and neither can help me. The watch is from 1984 and no links are available.

I measured the width and it is 16mm wide at the clasp. I am looking for 4-6 additional links. I have attached images of the watch.

Hope some one out there can help me find some additional links.

Thanks in advance for your help,
