Complete Your Build
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 rubber strap for daily comfort. Fully assembled and ready to wear.

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 rubber strap is integrated with a Royal Oak-style attachment for a clean transition from case to strap.
Frequently Asked Questions
How does the 41mm compare to the 37mm Royal Oak?
The 41mm has a larger case and more visible skeleton dial, better suited for wrists 17 cm and above. The 37mm Silver is more compact with an integrated steel bracelet. Both use the NH72 movement and sapphire crystal. Choose 41mm for more wrist presence, 37mm for a vintage-sized look.
Can I swap the rubber strap for a different color?
What dial size does the 41mm case use?
The 41mm Royal Oak case accepts 30.8 mm dials. Browse our 30.8 mm dial collection for compatible options. The skeleton dial is pre-installed and can be swapped by removing the caseback and movement.
