What is a Seiko mod

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.

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.

Very highly quality RO homage case

Very highly quality RO homage case. 37mm is a perfect fit for smaller wrists.

Perfect Case, Amazing Brand

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.

Unique and gorgeous watch case

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.

Gold Royal Oak Dial

Fantastic quality. Looks exactly like the image. Looks great.

Exactly what I was looking for

After years of research I finally found the 37mm case which is perfect in size. Excellent quality!

Perfect size, perfect platform.

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.

Solid case

The case is solid. Good finishing, good color good execution. I’m just a lil mad the screw driver for the case screws wasn’t included. I ended up absolutely mangling some of the screws for the bracelet and I have no idea how I’m going to replace them. If you like the octagonal style of watch and want a smaller size, this is the case for you. However with that being said, if you’re going to pay the premium for this case, you have to buy the separate screw driver for the case. Take that for what it’s worth.

Great Dial!

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!!

High Quality

Extremely well done case.

Love the case and love the company!

Shopping was fast to the USA. The case is of great quality. Nobody is doing the RO case in 37mm which fits my wrist so much better than those big ones on AliX. Not to mention the quality is worlds better than AliX. I really look forward to what they have coming down the pipeline. I see they have a new design in the works that looks incredible and very unique. I now follow them closely on Instagram so I don’t miss a thing. Can’t wait for what’s next!

Great Case & Service

The case is perfect and its great to find a Royal Oak style case in a smaller size. Had a self imposed issue with case back screws and after emailing the nomods team they got back to me extremely fast with a solution and replacements. Couldn't be happier with the product and the service.

The Royal Oak

I just received the watch. It's amazing. Much better in person than it looks in the pictures. It came with a custom box and a tool for adjustments. I asked Mithas to adjust it to my wrist size, and it was perfect. I ordered the 37mm, and it's perfect for my 7-inch wrist. As soon as I wore the watch, it looked quite elegant. I highly recommend it. If you like what you see in the pictures, you are going to love the watch.

What a case!

The case is really great built and the tolerances are great, there a couple of hairlines on the bracelet but it's not a big deal. The finishing is in line with the asking price and the extra set of screws is complete with every replacement.

Overall this is a great purchase and Mathias was super kind during the ordering phase. Now my AP collection is complete!

Great Case

Quality oak style case very impressed. Packaging was nice and secure, comes with useful tools as well. Only point of criticism is no half link but was told these will be available in march!

Very nice Case

Nomods was very helpful with the question i got.
Delivery was a little long due too christmas and new year.
Quality of the product blow mymind nothing to compare on what you found elsewhere, the finish, the saphire crystal, bracelet can be adjusted easely.
Movement dial and hands where easy to assemble.

Great case, only 2 gripes

2 bracelet screws broke (getting new ones) and no half link
