The HMC 804 caliber utilizes a double flat hairspring designed and manufactured in-house. This pair of hairsprings compensates for the movement of each spring's center of gravity during expansion, significantly improving precision and isochronism and ensuring continuous perfection. Furthermore, the pair of hairsprings reduces the wear typically imposed by a single hairspring, improving isochronism. Uniquely, the tourbillon is an interchangeable module, assembled and adjusted independently of the movement via a simple plug-and-play system for easy servicing.

The domed sapphire crystal case and captivating midnight blue fumé dial are characteristic of H. Moser & Cie.
The skeletonized 18KRG rotor features a bidirectional ratchet winding system, reducing the time required for full winding.
