Girard Perregaux first generation quartz repair?

[petaling108]

Hello,I am overseas but have friends in Malaysia.
I have an circa 1972 GP caliber 351 quartz watch that works intermittently despite new batteries.
where would I take this watch for repair?
I tried the AD in downtown KL once and they said its too old even for Switzerland to repair.
I have obtained some parts the Module.
Would (1)the shop at Amcorp(2)Swiss watch repair shops be good choices
