CLEARANCE SALE: Limited stock available. Items that show "Add to Cart" are still in stock.

There is only one wrist in the room wearing this.

The G-SHOCK Rainbow Mod is what happens when you take one of the world's most indestructible timepieces and hand it to people who refuse to leave well enough alone. A full spectrum rainbow colorway — applied across the bezel, case surround, and strap — that catches light differently depending on the angle, the room, and the moment.

Bold without being loud. Distinctive without trying. The kind of watch that makes people stop mid-conversation to ask where you got it.

Available in four distinct Rainbow builds. Each one different. Each one limited. Each one a one-way door — once the stock is gone, it does not come back.


Choose Your Build

🌈 Rainbow Mod — The original. Full spectrum bezel and strap on a classic G-SHOCK base. The one that started it all.

✨ Rainbow Sparkle Mod — Rainbow colorway with an added sparkle finish across the bezel. Catches light in a way a photograph cannot fully capture.

🖤 Rainbow Black Mod — Rainbow spectrum set against a blacked-out case and strap. The contrast makes the color hit harder.

🖤🥇 Rainbow BlackGold Mod — Rainbow bezel with black case and gold accent detailing. The most complex build in the series.


The Foundation

Every Rainbow Mod starts as a genuine Casio G-SHOCK — the same platform trusted by military units, search and rescue teams, and professional athletes who need a watch that simply will not stop working. 200-metre water resistance. Shock-resistant construction engineered to survive drops, impacts, and conditions most watches would not survive. A movement that has been proving itself for over four decades.

We chose it because custom work this considered deserves a foundation this capable.


⚙️ Original Casio Movement
Proven Japanese quartz — accurate, reliable, built to outlast trends.

🌈 Hand-Applied Rainbow Colorway
Full spectrum modification across bezel, case surround, and strap — applied by hand, matched throughout.

🛡️ 200M Water Resistance
Ocean, rain, pool. No hesitation required.

🔩 Shock-Resistant Construction
Military-grade G-SHOCK platform — the same foundation trusted worldwide.

✨ Four Distinct Builds
Rainbow · Rainbow Sparkle · Rainbow Black · Rainbow BlackGold. Each different. Each limited.

🎁 Free Luxury Gift Set Included
Premium watch box + exclusive owner's guide. Worth €59.

This is a clearance release. Four variants. Limited stock on each. Once any build sells out it is permanently retired — no restocks, no remakes. If the one you want is still showing as available, that is your window.

CLEARANCE SALE...

Hi, I’m Kevin, founder of ZJani Mods.

After 12+ years of building Seiko-inspired watches, we’ve made the decision to significantly reduce our collection.

This is the final release of many of our most popular designs.

Once these watches sell out, they are permanently gone.

No restocks. No remakes.

We’re clearing the remaining inventory at reduced pricing — but stock is already limited and moving fast.

Some models are already close to selling out.

If you’ve been waiting, this is your last chance to get one before they disappear.

When they’re gone, they’re gone.

Thank you for being part of our journey❤️

Uitstekend!

    Amazing looking piece!

    I’ve just ordered 2, one for me and one for a friend. I’ve emailed Daniel at support with a couple of questions, he’s replied very quickly with the answers. Great service.

    Perfect blend of precision and value!

    It arrived on time and feels and looks the part, is the right size for me, keeps very accurate time and it’s amazing value for money compared to some of the watches in my collection.

    Great communication by Ellie via email regarding the shipment. Once dispatched their tracking facility was great and I could follow my watch as it made it to my door.
