1.5 link for AP jumbo /15202

[bmwcsl]

I wandered into the AP dealer in Singapore and picked up a 1.5 link for my 2008 15202. I have only just tried to fit it and it seems the pin is smaller diameter than the rest of the bracelet so it wont fit. The part number is MR 404 133 ST. Anyone know if i have a link for a different bracelet? It looks spot on bar the pin and thus holes being smaller than the rest of the bracelet. 

Many thanks
