MS Factory Edition — White Rubber Strap
MS Factory’s execution of the RM 27-03 stands out for its ambitious use of a fully transparent sapphire case, integrating the baseplate and case body into a single coherent structure. This significantly improves structural rigidity while offering an unobstructed 360-degree view of the intricate mechanical architecture.
Powering this piece is a manual-winding tourbillon clone caliber. The movement architecture faithfully replicates the dramatic hollow bridge plate shaped like a Spanish Matador bull’s head, beneath which the barrel, gear train, and tourbillon escapement are prominently displayed. Power reserve is approximately 36 hours.
Measuring 17.8mm in thickness and weighing 86g, the case offers robust wrist presence, diverging from the ultra-light carbon of the genuine to deliver a unique sapphire aesthetic. The scratch-proof sapphire crystal features correct anti-reflective coating, ensuring the intricate skeletonization remains clearly legible under harsh lighting.
