Frequently Asked Questions

What is a Seiko Mod?

A Seiko Mod is a special watch hand-assembled from a prestigious Seiko automatic or hybrid movement, combined with high-quality aftermarket parts, usually made of 904L stainless steel. 

Have you ever dreamed of acquiring your ideal timepiece?

The purpose of Seiko mods is to bring the designs of luxury watches to a wider audience without resorting to counterfeit products, and by always using the best materials, such as sapphire crystal or ceramic bezels.

Seiko movement—rock solid and precise!

I own several watches, and the Seiko NH35 movement is a no-brainer. Reliable, accurate, and easy to maintain. After several days of use, I can confirm it keeps excellent time. Definitely a smart buy for anyone looking for a solid automatic movement without breaking the bank. I own several watches, and the Seiko NH35 movement is a no-brainer.

I was worried about water resistance… Tested & approved!

This was my biggest concern before ordering. I wasn’t sure if a Seiko mod would hold up in water or if I had to be extra careful. Took it in the shower, went swimming—no issues at all! No fogging under the glass, no leaks, nothing. Super reassuring! This was my biggest concern before ordering. I wasn’t sure if a Seiko mod would hold up in water or...

Best customer service I’ve experienced!

I had a question before buying, and they replied in less than 5 minutes. It’s rare to find such responsive and knowledgeable customer support. Even after my purchase, they followed up to check if everything was good. Way better than those companies that just ignore you.

OUR STORY

In a small London workshop, two watch enthusiasts, Alex Carter and Michael Hayes, set out to create something different. Passionate about horology and engineering, they were frustrated by the lack of affordable, high-quality timepieces that truly reflected individuality.


They discovered Seiko mods, a world where craftsmanship meets customization. What started as a personal project soon became Seikora—a brand dedicated to creating exceptional Seiko mods with authentic movements, premium materials, and a level of detail that rivals high-end watches.


Each timepiece is meticulously assembled to ensure durability, precision, and timeless style. Whether it’s the trusted NH35 movement, the scratch-resistant sapphire crystal, or the carefully curated designs, every watch is built to stand out and last.


At Seikora, we don’t just make watches. We craft timepieces that tell your story.
