you mean?? And when you say based on Piguet meaning it is still made in-house by VC but copying the Piguet movement or movement is bought from piguet. Sorry. Still new at this.
there are two Dual Time watches in VC's current lineup. One is the Matle Dual Time Regulator, which I had assumed you were talking about, and which uses the Piguet movement: There is also the Malte Tonneau Dual Time watch, which is based on a JLC movement...
