Can I service any of your watches locally?

Absolutely.

We use world-respected Seiko movements from Japan.

Since these are a gold standard in the watch world, they are easy to service.

Any local watch shop can help you out, so you never have to worry about finding a pro to keep it running like clockwork.

Your watches are fake and they will feel cheap in hand?

Those famous designs belong to everyone.
Big brands just keep them "off-limits" so they can charge you 10x more for a name.

We use the exact same "legendary" materials — 904L steel, sapphire glass, and rock-solid automatic motors.

When you hold it, you’ll feel the weight of a real watch, not a "cheap" toy.

These aren't fakes.

They are custom builds for people who want an iconic watch at an affordable price.

This isn't a replica.
It's a completely different thing.

A replica pretends to be something it's not. A mod doesn't pretend to be anything.

Let's clear this up.

A replica slaps a fake logo on a cheap case and hopes you don't look too closely. It's deception in a box.

A Moddy’s watch is the opposite.

We take a genuine Seiko movement — the same caliber trusted by watchmakers worldwide — and build a custom timepiece around it.

Our own dial. Our own case.

The design is inspired by icons — the same way every great watch made in the last 60 years has been inspired by something before it.

That's how horology works. Always has been.

The difference is simple:

A fake hopes you never find out what's inside.

A Moddys watch wants you to look closer.

I was unsure at first but I trusted them and my goodness they delivered a beautiful time piece. My Yacht-Master Seiko runs smoothly. Beautiful watch, worth the money and will definitely purchase again.

The Nautilus has a good weight to it, you can feel it’s made from quality steel and the mechanism is amazing. I've had loads of compliments, so I am looking forward to my next purchase.

I don’t usually write reviews but the Daytona I bought is stunning and looks a lot more expensive in person. Arrived earlier than it said it would as well which is good. Great company, will definitely be ordering again in the future

Good communication throughout. The built quality is second to none. The bracelet, the crown, everything feels like 5 figures. Keep up the good work, guys. I am very impressed as a first-time buyer. Thank you very much, I will be back

Why Moddy’s?

Everyone copies us.
Nobody matches us.

Other mod sellers use our images to sell their watches. Think about what that tells you about their product.

We could be mad about it. Honestly? It's flattering.

Because here's what they can't steal:

Our patented dial technology.

Moddys developed a proprietary method for reengineering mod components — precision parts and custom finishes that other sellers literally cannot replicate.

Our community.

130,000+ people didn't follow a stock photo account. They followed real watches, on real wrists, from real people who bought from us and kept coming back.

Our reputation.

Two years of warranty. Tens of thousands of watches shipped. Actual customer support from actual humans.

Each dial is finished by hand in batches of 50.

When this run sells out, the next batch won't ship for 3-4 weeks.

Not all mods
are built equal.

Most Seiko mod sellers are one guy, a workbench and a prayer.

We’re a little different.

Most guys get their first compliment within the first wear.

But we wanted to give you the full picture — the double-takes, the "where'd you get that?" moments, the feeling of glancing down at your wrist and actually loving what you see

If your Moddy’s watch doesn’t arrive at the quality you expected…

We'll refund every penny. No hoops, no hassle, no "well did you try..." emails from our support team.

Just reach out and it's done.

We can offer that because we know how good the quality of our watches is.

We're not worried.

Obsessed with the weight and finish on this custom build. It gives that $10k luxury aesthetic but in a piece I’m actually comfortable wearing every day. The perfect 'quiet luxury' addition to the collection.

Adding a touch of class to today’s fit. All the watches from Moddy’s hit that 'Old Money' vibe perfectly. My new favorite accessory for a sharp weekend look.

I’ve always loved watches with a story. This custom build feels way more personal than something off a shelf. The craftsmanship is insane, definitely a piece that will be in the rotation for years.

Gentlemen, if you want that high-end look without paying 5 figures, this is it. Clean, heavy, and goes with literally any fit.

I have pieces that cost 10x more, yet I find myself wearing this on a regular basis. Moddy’s is that good.

Just recieved my watch after approximately 10 days. Really happy with the build quality and look of the watch. Came with a nice little box and adjust screwdrivers. I just hope it stands the test of time. Definitely recommend this company.

I ordered the James Bond 007 “No Time To Die”. I was a bit sceptical about ordering a Mod watch but took the chance and I’m so glad I did as it is absolutely brilliant and I love seeing it on my wrist.
I would highly recommend Moddy’s and I’m just about to order the Blue Seamaster homage from them. Give them a look on their site I’m sure you will be tempted and don’t hesitate.

Excellent order experience

Firstly, their quality is trustworthy.
And although I asked about my order's progress and some question, they answered promptly.
The order period was a bit long(about three weeks) because they assemble it by hands, but it deserves to wait.
