What to Know Before Building Your Seiko Mod Royal Oak 37mm
Meta Description:
Considering a Seiko Royal Oak Mod? Discover what you need to know before buying the 37mm Royal Oak Mod case from Nomods — tools, coatings, bracelet care, and must-have add-ons.
Introduction: A New Chapter in Seiko Modding
Nomods started in 2024 with one goal in mind: create premium watch cases in modest sizes. While watch collectors worldwide are shifting their preferences toward smaller timepieces, the modding world still lacks options under 40mm.
We are proud to be the first to offer a high-quality 37mm Royal Oak case specifically for Seiko modding projects.
If you're building your own Royal Seikoak or want to upgrade to a more wearable version of the legendary design, this guide will help you make an informed decision before buying.
🛠️ Before Buying: What Tools Do You Need for Your Seiko Mod Royal Oak Build?
Assembling a Seikoak is easy! It's as easy as any mod, but to build a Seiko Mod Royal Oak at 37mm, you’ll need following:
-
A good screwdriver for the caseback
-
A screwdriver for removing the bracelet and links
These tools are essential whether you're assembling a full Seikoak watch or simply swapping a movement into our Royal Oak Mod Case.
Investing in proper tools ensures you don’t scratch your Seiko Mod case or strip screws during assembly. Quality builds start with quality preparation.
🔩 Plated Versions: A Quick Tip Before Removing Screws
If you’ve chosen a gold or PVD plated Royal Oak Mod case, you’re not just getting a stylish look — you're getting a case that has been dipped in a multi-step electroplating process.
During plating, grime and excess plating can settle in the bracelet screws. Before you start sizing your bracelet, take a moment to:
-
Rinse the bracelet in warm soapy water with a soft brush
-
Let it dry completely
-
Then gently remove the link screws
This simple cleaning step preserves the flawless finish and ensures your Seiko AP Royal Oak Mod feels just as premium as it looks.
🔍 Blue AR vs. Clear AR Coating: Which Crystal Is Right?
Our 37mm Seiko Mod Royal Oak cases come with two anti-reflective (AR) coating options: Blue AR and Clear AR. Each brings its own benefits depending on your dial and style preferences.
🔵 Blue AR Coating:
-
Adds a subtle blue tint under bright light
-
Pairs well with dials in silver, black, navy, or meteorite
-
Gives a luxury “glare-reduction” feel often seen in high-end Swiss watches
⚪ Clear AR Coating:
-
Completely invisible to the eye
-
Ideal for monochrome watches and dials in red, green and other colors that may crash with a blue detail.
-
Best when you want no color distortion at all
If you're modding a Royal Oak Mod watch with a skeleton NH72 movement, Clear AR is often preferred to show off every detail.
🧩 Which Add-Ons Should You Consider?
To make the most out of your Seiko Mod Royal Oak, we’ve developed a custom 1.5x link (half-link) specifically for this 37mm case.
Why it matters:
The bracelet is integrated, so small sizing adjustments are crucial. A standard full link can be too much; removing one might be too little. This half-link helps you fine-tune the fit — especially for smaller wrists.
For a perfect fit, don’t forget to add our custom-designed 37mm Royal Oak Seiko Mod Half Link — a must-have for fine-tuning your bracelet size.
✅ Conclusion: The Royal Oak Seiko Mod in 37mm Is Finally Here
Whether you're building your first Royal Oak Mod watch or you’ve completed a dozen Seiko mods already, this 37mm Seiko Mod case represents a perfect balance of luxury, size, and modding potential.
It's compatible with NH35, NH36, NH38, and NH72 movements, and offers the most authentic AP-style silhouette in a wearable size.
