Royal Oak 41mm Skeleton

The Royal Oak 41mm Silver is the flagship of the Seikoak skeleton lineup — a full-sized 41 mm case in brushed and polished 316L stainless steel with the NH72 skeleton movement visible through an open dial. The larger diameter gives the exposed mechanics more room to breathe than the 37mm version, making the rotor, bridges, and gear train more prominent on the wrist. Sapphire crystal, 100 m water resistance, and a matching steel bracelet for daily wear. Fully assembled and ready to wear.

What’s Included Fully assembled Royal Oak 41mm skeleton watch Matching metal bracelet (pre-installed) Nomods packaging Designed by Nomods The 41mm Royal Oak case uses the same octagonal bezel language as the 37mm, scaled up for a more commanding wrist presence. The alternating brushed and polished surfaces on the bezel create the light-play that defines the Royal Oak aesthetic. We chose the silver-on-silver combination as the reference build — natural stainless steel with silver dial accents keeps the focus on the exposed NH72 movement. The bracelet uses a Royal Oak–style integrated attachment for a seamless transition from case to wrist. Frequently Asked Questions How does the 41mm compare to the 37mm Royal Oak?
