VSF Ultra-Weighted Edition — Two-Tone Oyster Bracelet
The VSF 2026 edition of the reference 126503 redefines the two-tone replica landscape by integrating a high-density tungsten-steel alloy chassis. Weighing in at approximately 164 grams, this release successfully mirrors the exact mass of the genuine Rolesor model, addressing the most common tactile critique of two-tone clones. This specific architectural upgrade has established the VSF tungsten series as the benchmark for collectors prioritizing physical authenticity.
Inside beats the VSF Dandong 4131 clone caliber, a sophisticated automatic chronograph mechanism featuring a true vertical clutch and column wheel architecture. This movement delivers exceptional stability, eliminating start-stop stutter on the chronograph hand, and sweeps with the correct 28,800 vph frequency.
The 40mm case is machined from 904L Oystersteel, complemented by a 5-layer 18K PVD yellow gold wrapping on the bezel and center links to ensure an accurate hue. The deep gloss black dial features contrasting golden crystal sub-dials and is set with eight brilliant-cut synthetic diamond hour markers, offering a highly accurate visual profile under a sapphire crystal.
