MKS Factory Edition — Italian Cowhide Strap
MKS Factory’s iteration of the Vacheron Constantin Patrimony Perpetual Calendar 43175/000R-B519 represents a notable technical achievement in high-complication replica watchmaking. By focusing on the exact lug curvature and dial color consistency, this release addresses previous market shortcomings for ultra-thin dress pieces, offering a highly accurate visual profile.
Powered by a fully functional clone of the Cal.112QP, this movement features a balance wheel positioned identically to the genuine caliber. All sub-dial functions operate normally, maintaining the complex mechanical architecture expected in a perpetual calendar, yielding a power reserve of approximately 36 hours.
The rose gold-plated case measures 12.8mm in thickness, weighing exactly 93 g to mimic the heft of a traditional precious metal dress watch. The primary dial color is a deep sunburst blue, though our automated color analysis detects a warm metallic undertone, likely reflecting the delicately polished rose gold hour scales and hands in the reference imagery.
