A heartfelt tribute to a classic watch — understated and very well executed.

Mechanical By Design

NO BATTERY.
JUST A REAL AUTOMATIC MOVEMENT.

The NH35 winds from the movement of your wrist and can also be wound manually — the mechanical experience many watch enthusiasts specifically look for.

Before You Order

LET'S BE STRAIGHT WITH YOU.

If you're researching before buying, good. That's exactly what a watch buyer should do.

“IS THIS AN ORIGINAL SEIKO OR OMEGA?”

No — and we don't want there to be any confusion about that.

This is a custom-built ZJani Mods watch using a Japanese NH35 automatic movement and aftermarket components.

The design takes inspiration from classic professional dive watches, but it is not an original factory Seiko or Omega timepiece.

“SO WHY SHOULD I TRUST ZJANI MODS?”

Because we've spent 12 years building watches we'd be proud to wear ourselves.

We've served 12,868 buyers and our customer rating is 4.8/5.

Every piece is inspected before shipment and backed by our 180-day international warranty.

“WHY $100 OFF?”

We're transitioning our collection to its next phase and reducing the number of configurations we carry.

That means remaining inventory is being cleared rather than carried into the next collection.

Once this configuration is gone, no restock is planned.

A Note From Kevin

12 YEARS BUILDING WATCHES I'D BE PROUD TO WEAR MYSELF.

I'm Kevin, founder of ZJani Mods.

I've spent 12 years around custom watches, and the watches I've always appreciated most aren't the ones trying hardest to look expensive. They're the ones that simply feel right when you pick them up.

That's what I like about this SMP300 Classic.

You get the mechanical NH35 movement, sapphire crystal, ceramic bezel and substantial stainless-steel construction. The ingredients watch enthusiasts actually care about.

Every piece is inspected before it ships. You have my word on that.

And if there's ever an issue, email us. I read every email personally.
