1600 Jubilee Bracelet repair (extra link?) pics

[LanceS4803]

I have my 1976 Jubilee bracelet at Rolliworks for stretched bracelet repair. They said that when repaired, the bracelet would be shorter, and recommend an extra link be added.
I can't remember what the adjustment was before sending it in but found a couple of old photos. Am I right in that it appears the end is in the center of the clasp, will have enough adjustment to account for the now shortened bracelet?
Although I really don't want to buy and install an extra link, in the end, would that be a worthwhile investment?
Advice appreciated to keep my Grandfather's watch going for another 50 years.
