Curved caseback

With the curved caseback the middle part of the case sits a lot lower on the wrist utlimately making the design feel even slimmer.

Slim profile

These two elements allow for a super slim profile and premium feeling to the watch. This is a breakthrough in case design, challenging Seiko movements' main limits!

Frequently Asked Questions

What is a Seiko mod?+
A Seiko mod is a custom watch built using a Seiko or NH movement combined with aftermarket parts such as cases, dials, hands, and crystals. Mods can be bought prebuilt or created by DIY modders.
Do you sell both prebuilt Seiko mods and parts?+
Yes. NOMODS offers ready-to-wear Seiko mods and a full catalog of Seiko mod parts for DIY builders. You can choose to buy a finished watch or build your own.
Are your Seiko mods genuine Seiko watches?+
Seiko Mods must not be mixed up with original Seiko watches. All NOMODS watches use genuine Seiko/NH movements (e.g., NH35/NH36, NH70/71/72). The cases, dials, crystals, and straps are high-quality aftermarket components assembled by experts.
Do you ship worldwide?+
Yes. We ship worldwide from Norway with secure, tracked delivery options. Shipping times vary by region, and all orders are carefully packed for safe arrival.
Are Seiko mods water resistant?+
Many builds are designed for water resistance, but it is only guaranteed if the watch has been pressure-tested and rated. Always check the specifications on each product page.
Can I return or exchange my order?+
Yes. We accept returns and exchanges on unused items within the stated return period. Please see our Refund Policy for details.

Perfect companion to the gunmetal 37mm Royal Oak case.

This dial compliments my 37mm Seikoak beautifully along with the rose gold hands. The fit was perfect and the gunmetal watch is one of my favorites.

Unexpectedly great and precise workmanship!

As advertised and expected

As advertised and expected. Genuine TMI part.

Beautiful case and bracelet

Beautiful case and bracelet. All parts fit well, the only issue came when resizing the bracelet. I should have read through the website first - I hadn't read the warning to wash the bracelet in warm soapy water first and I had a screw become stuck. It all worked out fine in the end, just a minor annoyance. The 37mm size fits my 7-3/8" wrist much better than I thought it would. I like it so much that I ordered a SeikoNaut case/bracelet which I'm currently waiting for.

Just a fake

Just a fake watch

Hi! Thank you for your review, though I don't get your point. Your order contains a dial and a set of hands for Seiko Modding, not a complete watch. If you are not satisfied with the product we have a return policy of 30 days, but I can not see any requests about that. Please help me understand, and I will happily help you!

Best wishes,
Mathias

Great finish

The case is well made and polished. Extra screws are included which is appreciated.
Shipping was a little bit slower than I expected, but it happens.

Excellent quality workmanship on the entire watch

Excellent quality workmanship on the entire watch. Bracelet is well polished and looks amazing!

High quality case will be purchasing again in possibly the 37mm size.

High quality case waiting for two 1.5 links to complete the fitting due to having a large wrist.

Perfect fit

Perfect fit in my NH movement and petrichor case, thanks!

Bought the case

Bought the case. It is really a unique product that doesn't exist anywhere else in the market. For anyone who likes Royal Oak and like a smaller footprint, this is an unmissable offering. Thank you Nomods.

Perfect Seikoak mod

Scam

Scam

Hello,

I’m sorry to see this review. Just to be clear, your order was shipped on time (28th of July) with Posten.no (Norway’s national postal service) and handed over to USPS in the US, where tracking shows it was delivered. When you told me it hadn’t arrived, I started contacting both postal services and got back to you as soon as I had any news. This took about five days, which I agree is longer than ideal, but their reply was slow due to low staffing.

The fastest way to solve this is for you to contact USPS, which I asked you to do three times. You declined and then stopped replying. Two days later, this “scam” review appeared.

Of course, you’ll get a refund if the package truely never shows up, but right now we’re still trying to locate it, and it’s far too early to start calling me a scammer or sending harassing and threatening messages.

This is a passion project, and I put a lot of effort into treating people fairly and being transparent. I’m still happy to help with USPS or open a claim if you’d like to get this resolved. You are always welcome to contact me, or reply to my previous message.
