Help needed sourcing 78340 link

[neversummer]

Hello folks!

Here is the problem. My mother have recently had a 60th anniversary and guess what did I giver her as a present? Right you are, a watch! Its a nice second hand 26 mm Lady No date 67180 on 78340 bracelet. No papers, but bought from a respectable Rolex dealer in Sweden who opened a caseback and demonstrated me the movt.

However it never occured to me to check the size of the bracelet since my mother have small wrists. On the anniversary day the freaking watch was too small! She could close the clasp but it sits too damn tight.

Does anyone happens to know where to source 1 link of 78340? Gen or rep? Would a rep link fit? Or is it stupid to "spoil" the gen with a rep link? I am in pain guys, please help!

Below are some pics of the timepiece.
