The Rose Gold Royal Oak 41mm brings a warm, refined finish to the largest integrated-design case in the Nomods catalog. The rose gold coating over 316L stainless steel catches light with a subtle pink-gold warmth that pairs naturally with rose gold dials and hands. At 41 mm with a 51 mm lug-to-lug span, this case delivers bold wrist presence while the 12.2 mm thickness keeps the profile controlled. The octagonal bezel features brushed flats and polished bevels, with a polished rehaut that frames the dial. Sapphire crystal in Blue AR, Clear AR, or No AR, screw-down crown, and 100 m water resistance. Fits NH35, NH38, NH70, NH71, and NH72 movements. Includes spacer ring for 30.8 mm dials.

Why We Chose This Case
Rose gold is one of the most requested finishes in the Seiko modding community, but most available cases use cheap plating that chips within months. The Royal Oak 41mm Rose Gold uses a coating process that holds up through daily wear. The rose gold shade was selected to complement the warm champagne tones of the NH72’s bridges, so skeleton builds look cohesive from bezel to movement. Even with an NH35 and a solid dial, the rose gold case adds warmth that natural steel cannot replicate. The polished rehaut provides a bright ring of contrast against the rose gold surfaces, adding depth to the dial window.
Frequently Asked Questions
What movements fit the Royal Oak 41mm case?
The NH35, NH38, NH70, NH71, and NH72 all fit without modification. These cover standard automatic, skeleton, and open-heart configurations from the Seiko NH movement family.
What dial size fits this case?
30.8 mm dials fit with the included spacer ring. 31.8 mm dials fit directly without the spacer. The Rose Gold Skeleton Dial is a direct match for this case.
Will the rose gold finish wear off?
The rose gold coating is more durable than standard electroplating and holds up through normal daily wear. Avoid abrasive surfaces and harsh chemicals. If coating durability is your primary concern, the Silver version in natural stainless steel will not show wear in the same way.
What handset should I use with the 41mm case?
Use longer hands designed for larger dials. Standard-length hands built for 28.5 mm dials will look undersized on the 41 mm dial opening. The Royal Oak Rose Gold Hands are sized for this case and match the finish.
