Hi I'm trying to nail down all of the elements in a Harry Winston Excenter Bi-Retrograde, and I'm assuming that the key elements are:
1. 3306 Girard-Perregaux base
2. An Agenhor module for the retrograde movement powered by the 3306
Is that correct? Is there somewhere I could see what the Agenhor module looks like?
Thanks,
Bill
