Changing your PAM's marker to gold?

[Shade]

Hi, I was just wondering if we can opt to switch our Panerai's marker to a gold one...

I currently have a 312 and I would love to switch the hour, minute and second markers (or needles) into a gold one, they're silver at the moment...

Anyone have an idea about doing it or the cost and where?

I live in Asia, Indonesia specifically - I heard Singapore can get it done, but I tried calling and they haven't gotten back to me with a clear answer just yet...

Any information would be appreciated.

Thanks!
