N1 Factory Edition — Leather Strap with Ceramic Fold Clasp
The N1 Factory iteration of the Speedmaster White Side of the Moon (311.93.44.51.04.002) represents a significant technical leap in ceramic case manufacturing. Unlike earlier replicas that relied on painted steel inner cores, this model is milled entirely from solid high-density Zirconium Oxide (ZrO2) ceramic, achieving the exact visual depth and physical scratch resistance of the authentic piece. It stands as a benchmark for collectors seeking the precise double-register dial layout without the compromises typical of modified 7750 base movements.
Powering this reference is the N1 custom-developed 9300 integrated chronograph caliber. Its defining horological achievement is the fully functional 3 o’clock subdial, which utilizes a true co-axial double-hand mechanism to track both elapsed hours and minutes simultaneously. Operating at 28,800 vibrations per hour, the movement replicates the genuine Co-Axial escapement’s visual architecture through the sapphire caseback while delivering an approximately 40-hour power reserve.
The 44.25mm case exhibits a sophisticated interplay of high-polish and fine-brushed finishing, demanding strict manufacturing tolerances to prevent ceramic micro-fractures. The white ceramic dial is meticulously flattened and polished, featuring 18K white gold style rhodium-plated indices filled with Swiss Super-LumiNova. A matte Chromium Nitride tachymeter scale on the bezel provides stark, highly legible contrast against the pure white aesthetic.
