- NH72 skeleton movement for visual depth and precise timekeeping
- Muted finishes in gunmetal, sandblasted silver, or matte black
- Sapphire crystal with anti-reflective coating
- Color-matched rubber straps in storm blue, forest green, and clay brown
- Design inspired by nature and post-rain calm

FAQs
A “Seiko Mod” refers to a custom Seiko watch that has been altered to match an individual’s style or functional needs.
Modifications can be purely aesthetic, such as changing the dial, case, hands, or bezel, or functional, such as improving movement accuracy or durability with features like water resistance. These modifications provide watch enthusiasts the opportunity to create a unique timepiece that fits their personal preferences and enhances their watch-wearing experience.
Seiko modding is a fun and creative way to customize your watch. If you’re just starting, you’ll need basic tools and parts like dials, braces and hands to personalize your timepiece. Explore our shop for compatible parts, and feel free to reach out for help identifying the right components or installing them. Our resources are here to make your modding journey easy and enjoyable!

Really well made, very happy with the product.
Very highly quality RO homage case. 37mm is a perfect fit for smaller wrists.
This is the perfect size for this style of case. The quality of the cases is top-notch, they feel and look excellent. Additionally, Mathias from Nomods is also very friendly and professional and helped me out with all my questions and customization requests.
Perfect size, perfect size case with the bezel being the right size. It is not too thick or too narrow, it is just right
Very nice case and very good quality
Nice seller
I am creating a custom watch build for my brother who works at a gym. I wanted something equal parts sport and elegance and the Petrichor meets and exceeds my standards for both. Really solid build quality with exceptional finishing, and a comfortable micro-adjustable bracelet to boot. I will be buying from NoMods again.
Fantastic quality. Looks exactly like the image. Looks great.
I recently ordered a watch case from this company and was blown away by the quality. The craftsmanship is outstanding — solid, well-finished, and clearly made with attention to detail. It exceeded my expectations in every way.
What impressed me even more was their customer service. There was a small issue with the shipping, but they handled it quickly and professionally. They responded fast, kept me updated, and made sure everything was resolved without any hassle.
It’s rare to find a company that delivers both top-tier products and great support. Highly recommended if you’re looking for premium watch modding cases and a team that truly stands behind what they sell.
After years of research I finally found the 37mm case which is perfect in size. Excellent quality!
I’ve always loved the look of the Royal Oak, really any Genta case design. I’ve been a fan of his work for as long as I can remember. When I came across the Nomods website I was blown away. Not only did they sell one of my favorite case designs of all time, they sell it in a wide variety of color options and what I consider the perfect size. There are other Royal Oak cases out there but this is the only one in 37mm that takes a 28.5mm dial with zero modifications. I’m very excited to see what Nomods has planned for the future with new releases. They are doing things no other mod store is doing.
Mathias from Nomods is excellent, and very responsive. I had a few questions about the product and he got back to me right away and was very helpful. I ended up buying the 37mm AP case and skeleton dial and they are beautiful and well made. I appreciate the quality and customer service!!
