FAQs — Seiko Mod Parts

Are all Parts compatible with NH35/NH36?+
Most mod parts are designed for NH35/NH36 movements since they’re the most common in Seiko builds. Always check each product’s fit notes for exceptions.
What case sizes are supported?+
We stock parts for popular SKX/5KX builds (42 mm), Royal Oak 37 mm/41 mm, and Aquanaut-style cases. Each collection notes the matching case size.
Do I need to modify dial feet or hands?+
Most dials and hands fit directly onto NH35/NH36. Some builds may require trimming dial feet or confirming hand hole sizes. Fit notes are provided in every listing.
Which crystals and bezels fit my case?+
Crystal height and bezel compatibility depend on the specific case. Larger dials (30.8 mm) often pair with taller or domed sapphire crystals. Always cross-check the case specifications.
Can I mix and match Parts across collections?+
Yes — that’s the idea of modding. As long as the movement, case size, and fit notes align, you can combine cases, dials, hands, bezels, and crowns freely.
I’m new to modding — where should I start?+
A good starting point is choosing a case and movement (NH35/NH36), then adding a dial and hands. From there you can customize bezels, inserts, crystals, and straps.

Build Your Own Custom Seiko Mod with Premium Parts

Seiko modding has become one of the most creative trends in the watch community, giving enthusiasts the freedom to design a timepiece that reflects their personality. With the right Seiko mod parts, you can transform a standard Seiko watch into something entirely unique — whether it’s inspired by iconic luxury models, rugged tool watches, or bold contemporary designs. At Nomods, we provide a complete catalog of mod parts so you can create a watch that’s as original as you are.

Cases – The Foundation of Every Build

The case sets the tone for your custom mod. We stock a wide variety of SKX007 and SRPD-compatible cases as well as luxury-inspired designs such as Submariner, Royal Oak, and Nautilus styles. Each case is engineered for precision fit, allowing you to build with confidence knowing every component will align perfectly.

Crystals – Superior Clarity and Protection

Upgrading the crystal is one of the most impactful mods you can make. Our sapphire crystals offer unmatched scratch resistance compared to standard Hardlex or mineral glass. Choose between flat, domed, or double-domed styles, with anti-reflective coatings available for maximum legibility in any lighting.

Dials – Define the Personality of Your Watch

From minimalist matte designs to vibrant sunburst finishes and textured patterns, Seiko mod dials are the centerpiece of your build. Whether you want a vintage-inspired diver look, a sleek dress dial, or something experimental, our range ensures you’ll find the perfect fit for your vision.

Bezels & Inserts – Instant Style Upgrades

A bezel swap can completely transform the character of your mod. Our selection includes rotating bezels and high-quality inserts in ceramic, aluminum, and steel. From classic dive bezels to GMT styles, you can change the function and look of your watch with ease.
