Girard Perregaux bracelet for Chronometer HF Gyromatic...like the one in this ad.

Hi OFers.

Probably a long shot, but I have seen amazing things happen here on OF. I'd be interested to know whether anyone has a bracelet for the Chronometer HF Gyromatic that they might consider letting go? Rather unhelpfully, I do not know the reference number of the bracelet (anyone?) but the head I'm looking to fit it to is the same as the one in the ad below...

Thanks all.
