If you are having a hard time removing the screws from the bracelet, take the case and bracelet under some warm soapy water and wiggle each link back and forth. This will clean out residue from production which makes the screws easier to remove and improve the bracelet quality over all

AR coating stands for Anti reflective coating and reduces the reflection in the crystal enhancing visibility. Blue AR has a slightly tinted reflection while Clear AR has not.

No it does not! Our 37mm Royal Oak Seiko Modding case arrives as one complete case, and is ready to house a movement straight from the box.

In order to make this Seiko Mod Case as thin as possible, there is limited room in the back of the case. Therefore some custom NH35 rotors do not fit. Pay close attention to the respective rotor. Does it exceed the height of the middle screw? If yes then it may be too thick for this case.

We recommend a 28.5/29mm dial for our 37mm Royal Oak Case. The typical 31.8mm mod dials that many Royal Oak Mod Cases use are too big.

What Inspires This Case

The Nomods Royal Oak 37mm Seiko Mod Case draws inspiration from the timeless geometry of the Audemars Piguet Royal Oak, reimagined for the Seiko Modding community. Built for creators who demand precision and elegance, this Seiko Modding case blends Seiko mod parts compatibility with high-end design cues — integrated lugs, crisp brushing, and balanced proportions that make it ideal for both skeleton and classic dial builds. Its compact 37mm profile captures the essence of modern luxury while maintaining the technical adaptability Seiko modders need.

Why 37mm Is Perfectly Proportioned

One of the most appreciated details among Seiko modders is the perfect harmony between the 37mm case and 28.5mm OEM Seiko dials. This combination achieves a true “factory fit” look — not oversized, not cramped — resulting in a balanced visual frame that enhances both readability and wrist comfort. Whether paired with a skeleton NH72 or a solid NH35 dial, the dimensions ensure flawless alignment between the rehaut, crystal, and dial edges, giving every build a clean, professional appearance.

The Royal Oak Seiko Mod 37mm case therefore isn’t just about looks — it’s about perfect proportion. Every millimeter is optimized to keep the Seiko dial centered, the chapter ring aligned, and the overall aesthetic consistent with high-end integrated-bracelet sports watches.
