What Is A Seiko Mod?
Not a replica. Not a fake. A custom watch built around a genuine Japanese Seiko NH35 automatic movement — the same engineering that powers Seiko's own $500–$2,000 watches, housed in a premium custom Oyster case with a dial you won't find anywhere else.
Genuine Seiko NH35 Movement
We start with an authentic Japanese NH35 automatic movement — 24 jewels, 41-hour power reserve, ±15s/day accuracy. The beating heart of every watch we build. Not a clone. Not a Chinese copy.
Premium Custom Components
Sapphire crystal (scratch-proof), 316L stainless steel 39mm Oyster case, and a custom green tea sunburst dial with warm beige undertones. Every part is selected for quality, not cost.
Hand-Assembled & Inspected
Each watch is built by hand in our workshop — movement regulated, hands set precisely, case pressure-tested. It leaves our bench only when it meets our standard.
Think of it like this: You're getting Japanese Seiko engineering — the NH35 movement found in the Seiko 5 Sports and Presage lines — in a custom-designed watch built to our specifications. Same heartbeat. More character. Half the retail price.
Premium Where It Counts
These are the components that separate a serious watch from a disposable one. Every part is chosen to last.
Seiko NH35 Automatic
The heart of the Green Tea Oyster Mod. A legendary Japanese automatic movement that winds itself with the motion of your wrist — no battery, no quartz, just precision engineering.
🔧 Genuine Seiko NH35 movement. Made in Japan. Installed and regulated by hand in our workshop.
Every Angle
The Green Tea Oyster Mod from every perspective. No renders — just the watch.
What Owners Say
to a friend
"The green tea dial is something else — photos don't capture how it shifts in the light. One minute it's a deep sage, the next it catches a warm olive tone. The NH35 is running at +3s/day which is incredible. Paired it with a leather strap and it looks like a $1,000 watch."
"Was looking for something unique that wasn't another black-dial diver. This green tea dial is subtle and elegant — works with a suit or jeans. The 39mm Oyster case is perfectly proportioned for my 6.75in wrist. Beige nylon strap is comfortable right out of the box."
"Third Emperor Mod I've bought and they keep getting better. The dial alignment is perfect, the NH35 is regulated beautifully, and the sapphire crystal is flawless. This green tea colour is genuinely original — never seen anything like it on a production watch."
"The value here is absurd. NH35 automatic, sapphire crystal, 316L case, and a dial this beautiful — all for under $300 shipped. My local watchmaker confirmed the movement is genuine Seiko and the build quality is excellent. Already planning my fourth."
Worn By Our Customers
Real photos from real owners. No renders. No Photoshop.
I started Emperor Mods because I was tired of choosing between overpriced retail watches and cheap fashion quartz. A Seiko mod gives you Japanese engineering — the same NH35 movement Seiko puts in their $500+ watches — in a custom design that actually reflects your taste.
Every watch is hand-assembled in our workshop. I personally inspect each build before it ships: movement regulation, hand alignment, bezel action, bracelet finishing. If it's not right, it doesn't leave.
We've built over 2,400 watches with over 1,800 shipped to US customers. Each one ships with a 1-year warranty. No questions asked, no hassle.
