N1 Factory Edition — Matte Black Calf Leather Strap
N1 Factory’s iteration of the Speedmaster Dark Side of the Moon Pitch Black (Ref. 311.92.44.51.01.004) represents a significant technical milestone in ceramic chronographs. Moving past the limitations of earlier releases, this version features a fully realized solid Zirconium Oxide (ZrO2) ceramic case and a dial constructed from a single block of matte ceramic, perfectly capturing the stealth aesthetic of the genuine article.
At its core lies the N1 custom Calibre 9300 integrated chronograph movement. Operating at 28,800 vph, this customized architecture achieves what previous iterations could not: a fully functional dual-hand coaxial sub-dial at 3 o’clock that tracks both chronograph hours and minutes simultaneously. The movement utilizes a dual-barrel design yielding approximately 40 hours of power reserve, ensuring reliable timing operations.
The 44.25mm case commands presence with a 49.8mm lug-to-lug profile and a 16.5mm thickness, accommodating the complex double-domed sapphire crystal. The Pitch Black moniker is honored through the Super-LumiNova application on the tachymeter bezel, indices, and hands, delivering an intense green emission in low-light conditions. The watch is secured by a matte black calf leather strap with ecru stitching and a dedicated ceramic folding clasp.
