Need help identifying and locating a part for WAF111C Aquaracer please

Hoping for some help. I was trying to adjust the bracelet on my WAF111C Aquaracer and the "spring bar" (not sure that is the correct word for it) went flying across the room and I lost it. I've tried ordering generic spring bars off Amazon and eBay, but they are too thick. I measured the width/length to be 17mm and the thickness must be less than 1.5mm as 1.5mm spring bars were too thick.

Any information on where I can source one of these without spending too much?

Thanks!

Contact an authorised TAG Heuer dealer and ask, prices for "official" spring bars are not expensive at all in my experience
