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 Gunmetal Royal Oak 37mm Seiko Modding Case started as an experiment in surface treatment. The goal was to take the clean, architectural lines of the Seikoak design and give them a darker, more utilitarian feel — something closer to industrial titanium than luxury steel. The brushed coating has a muted sheen, which lets the facets catch light without appearing polished or loud.

This color choice came from wanting a version that feels functional first — the kind of finish that looks even better once it’s been worn a while. It’s built for Seiko modders who lean toward stealthy builds: smoked sapphire, skeleton NH72 movements, and blacked-out chapter rings. Despite the darker tone, it keeps the same crisp geometry and integrated-lug proportions that define the Seiko Royal Oak shape.

Why 37mm Is Perfectly Proportioned

The 37mm case size wasn’t chosen by accident. It’s the point where 28.5mm Seiko dials line up exactly with the rehaut, keeping the dial centered without creating excess gap. During testing, we found that a fraction larger made the case feel loose around the dial, while smaller designs cut too close and disrupted the clean visual flow.

In use, this Seikoak Mod case wears compact, balanced, and technical — ideal for builders who want their watch to feel cohesive rather than oversized. It supports all standard Seiko mod parts (NH35, NH36, NH72), maintains the correct hand clearance, and keeps the dial spacing precise. It’s a dark, balanced foundation for any Seiko Royal Oak mod that values both restraint and detail.
