MKS Factory Edition — Italian Calfskin Strap
The Vacheron Constantin Fiftysix collection draws inspiration from the historic reference 6073, blending classic elegance with modern proportions. MKS Factory establishes the benchmark for the Complete Calendar complication with this 4000E/000R-B065 replica. By successfully integrating functional case-band pushers and correcting the calendar hand stack, MKS achieves a high level of mechanical parity with the genuine reference that satisfies strict forum consensus.
Powered by a dedicated Caliber 2460 Q/1 clone, this movement took 18 months of intensive research and development to properly engineer. The architecture correctly positions the balance wheel to mirror the genuine caliber’s layout. It supports all authentic complications—including the day, month, pointer date, and moon phase—delivering a power reserve of approximately 36 hours. Furthermore, the quick-adjust buttons recessed into the case band operate identically to the authentic Vacheron caliber, allowing seamless mechanical adjustments.
The rose gold-plated case measures exactly 40mm in diameter and an ultra-thin 10.6mm in thickness, matching the verified specifications perfectly. The Sepia Brown dial features correct applied Arabic numerals, bar-shaped hour markers, and a box-shaped sapphire crystal that faithfully recreates the retro aesthetic of the Fiftysix line. The intricate dial layout, with twin rectangular windows at 12 o’clock, is executed with sharp typography and precise alignment.
