at the SF GTG a few weeks ago?
It was on a new Hermes strap. It cost about $450US.
I have to say it is by far the most comfortable brand new strap that I've owned. Soft and supple. Better than a similar CF strap new. I cannot comment on the durability/wear characteristics...it has been on the watch for about a month and I've only worn it a few times total.
Hope all is well,
Mike
