Gshock Bigger Longer and Uncut

Hi everyone, meet my extra-large G-Shock.

I call it G-Shock Bigger, Longer, and uncut — yeah, the name’s ridiculous, but so is the build.

I’ve always liked G-Shock watches. I own a couple, and they’ve held up through everything — drops, splashes, even a few accidental slams. But after a while, I wanted something different. Something bigger.

So I thought: what if I made one that’s not just oversized, but absurdly oversized?

I started by modeling the Metal Shock in 3D, scaled it way up — like, wall-clock big — and then added a real clock mechanism inside. Painted the outer shell silver, gave the inside a bright orange pop, and stitched a proper strap on the back so I could actually wear it. It’s bigger than my head, and yes, it works.

This thing is larger than my head. It’s not subtle. It’s not practical. But it’s real, it works, and it turns heads like nothing else I’ve built.

It’s part sculpture, part satire, part tribute to the design language of a brand I love. And it’s a reminder that sometimes, the best projects come from asking, “What if I just... went way too far?”

This Article is about the complete build guide of this Oversize clock. Lets begin!

Following were the supplies you need!

1. 3D printer- Because I used 3D printed parts for this build, but honestly, you could make the whole thing out of cardboard too if you’re feeling crafty. Want a cardboard version? Drop a comment and I’ll prepare one out!
2. M2 Screws
3. Clock machine
4. Paints - I have used three major paints colors that include Black Orange and silver dust paint.
5. Old Watch as Strap part (using old Casio Vintage A-158WA metal frame as Strap)

These were the materials I used in this build and they are pretty simple to arrange.

We started the modeling process by trying to find a good front-facing image of the Casio GM-2110D-4A.

I want able to find one that worked, but that wasn’t a big issue. G-Shocks tend to share design elements across models, so I used the front view of the Casio Shock Jellyfish instead.

I imported the image into Fusion 360 as a canvas and used the calibrate tool to scale it up to around 240mm. That size worked well with my 250×250×250 printer — keeping everything under 250mm was the priority, and 240mm felt right, so I went with it.

After tracing all the lines, shapes, and text from the reference image, I had a single solid model of the watch. To make things easier during assembly, I split the model into separate parts.

First, I cut out the circular inner section — the part that shows the time, has the G-Shock branding, and includes the week selector dial. This section was completely separated from the main body. I mounted the clock mechanism from the back and secured it using a lock nut tightened from the front. That keeps it firmly in place. I also designed custom 3D-printed hour and minute hands to fit the mechanism. For the week selector, I added a static arm — it doesn’t move, but it’s there to match the real Casio design.

Next, I separated the hexagonal watch face. This part has all the text like “G-Shock,” “Adjust,” “Mode,” etc. I traced each letter manually using line and spline tools in Fusion — super tedious, but it worked out in the end.

Behind that, there’s another hexagonal frame part that gets screwed in. It adds thickness and acts as a structural support to hold everything together.

For the strap, I reused the metal band from an old Casio A-158WA. I made a custom part to hold the band securely, and that holder is pressure-fitted onto the back of the hexagonal frame. That’s what makes the whole thing wearable — a giant, functioning G-Shock you can actually strap on.

For this build, we used a total of 8 printed parts. The top, mid, and back sections were printed in white Hyper PLA on our Anycubic Kobra S1. These are the main structural pieces, so we went with a tougher filament for durability.

The frame and bottom parts were printed in regular pink PLA not for aesthetic reasons, but because I had a bunch of unused pink spools lying around. Since the whole body was going to be painted silver anyway, the base color didn’t really matter.

The remaining components which were the minute hand, hour hand, and the week selector were printed in grey PLA. We’re keeping the grey as-is for those parts, since it gives a nice contrast and fits the overall look

Now comes the most fun part of this project — painting.

I’ve always enjoyed painting; it’s one of my favorite parts of any build. I’ve even done a few paint-focused projects before (you can check those out in the link below if you’re curious).

1. We started by painting the center part of the clock (the round section that shows the time and has all the branding).
2. I used a bright orange color on the inside, just like the real G-Shock. Then I added some grey where needed, based on the original design.
3. For the text like “G-Shock” and “WR 20 BAR,” I used black paint and filled in each letter by hand. It took some time, but it looked great in the end.
4. After that, I painted the frame parts and the top shell. These parts make up the outer body, so I used metallic silver paint to give them a metal look.
5. Some of the parts were 3D printed in pink PLA (because I had extra), but the silver paint covered it well.
6. The grey PLA parts which were the hour hand, minute hand, and week selector were left as they were. The grey color matched the rest of the build, so I didn’t need to paint them.

1. Assembly process starts by adding the Middle Center Part inside the Frame Part.

1. After putting together the frame and middle sections, we added the back frame part. To hold everything in place, we used eight M2 screws to join the back frame with the rest of the build.
2. For extra strength, we added hot glue on the backside. That helped lock everything in and made sure the parts wouldn’t shift or come loose.

Now it’s time for the watch strap assembly.

1. I started by taking the body of an old Casio vintage watch and attaching it to the custom-designed watch holder part.
2. To secure it in place, I used two M2 screws.

1. Now we added hot glue to the front face of the watch, then placed the front frame part on top. This piece finishes the front section and makes the whole thing finally look like a Casio G-Shock.

1. We start by placing the clock mechanism from the back side of the center part. It has a M7 screw part that fits into the central hole of the clock body.
2. Once aligned, we tighten the nut that comes with the clock machine to hold it firmly in place.

1. Now we added the hour hand, then the minute hand, and finally the week selector each in their proper place.
2. The hour and minute hands were mounted directly onto the clock machine, while the week selector was placed into the hole made for it in the center part. Simple and clean.

For the final step, we added the watch strap part to the back of the frame assembly. It’s pressure-fitted into place, but to make sure it stays secure, we applied superglue. That locked the strap in firmly and with that, the full clock assembly was complete.

After all the modeling, printing, painting, and assembly, what we ended up with is something that’s hard to ignore: a fully functional, oversized Casio G-Shock that’s bigger than my head and definitely bigger than any watch I’ve ever owned.

Wearing it feels like strapping a piece of architecture to your arm. It’s not meant to be practical. It’s meant to be fun. A statement. A tribute to the design language of a brand I’ve always admired, taken to a completely unnecessary but deeply satisfying and totally extreme.

This project started as a “what if” and ended up as one of my favorite builds. It’s simple at its core, just a clock but the scale, the detail, and the ridiculousness of wearing it make it something special.
