A Canadian creator has turned a routine gadget comparison into a full‑blown science experiment by sending a genuine Apple Watch and a Temu lookalike through a CT scanner. Instead of relying on spec sheets or unboxing impressions, he used industrial imaging to expose how each device is built from the inside out. The resulting cross‑section views show a stark divide between a tightly engineered smartwatch and a bargain copy that looks similar on the outside but tells a very different story in three dimensions.
The scan does more than settle curiosity about what is hidden under the glass. It highlights how design discipline, safety margins, and long‑term durability are literally baked into the structure of the real Apple Watch, while the Temu dupe appears optimized for cost above all else. For anyone tempted by ultra‑cheap wearables that mimic Apple’s design, the images offer a rare, forensic look at what that tradeoff really buys.
The Canadian CT scan experiment that went viral
The showdown started with a simple premise: take a real Apple Watch and a Temu smartwatch that imitates its look, then run both through the same industrial CT scanner to see what separates them. The Canadian host, identified in the video as Jan, set up the test as a “battle of the devices” between Apple and Temu, framing it as a way to move beyond surface impressions and look directly at the internal engineering. Instead of cracking the cases open with tools, he relied on non‑destructive imaging so every screw, chip, and battery weld would be visible in situ.
In the full walkthrough, Jan carefully rotates and slices through the 3D scans, pausing on key structural differences that would be impossible to spot from the outside of either watch. The video, titled “We CT Scanned an Apple Watch VS Temu Watch,” shows how the real Apple Watch is densely packed with components that appear precisely aligned, while the Temu device has more voids, rougher geometry, and a noticeably looser internal layout, all captured in the same industrial scan of the two watches side by side in a single comparison.
Inside the real Apple Watch: dense, deliberate engineering
When Jan turns his attention to the genuine Apple Watch, the CT images reveal a compact, layered structure that looks more like a miniature computer than a simple wrist accessory. The logic board, battery, haptic motor, and sensors are arranged with almost no wasted space, and the casing appears to cradle each part with consistent clearances. According to his breakdown, the real Apple Watch has a long list of integrated modules that are tightly stacked, which helps explain how Apple fits features like heart rate tracking, GPS, and cellular radios into a slim profile without obvious bulges or flex.
The scan also highlights how much effort goes into managing heat, sealing, and impact inside Apple’s design. Components that generate warmth are clustered near structural supports, and the battery is boxed in with what looks like reinforced bracketing rather than floating loosely. Earlier industrial CT work on other Apple hardware has shown similar patterns, with detailed imaging of AirPods Pro and a MacBook MagSafe charger revealing carefully shaped heat sinks and shielding that channel thermal loads away from sensitive parts, and the Apple Watch scan fits neatly into that same philosophy of over‑engineering the internals for reliability.
The Temu dupe: familiar shell, very different core
By contrast, the Temu smartwatch that Jan scans looks like a near twin to the Apple Watch from arm’s length, but the CT images show a very different story once the casing disappears. The internal layout is simpler and more sparse, with a smaller logic board and fewer discrete modules, and there are larger pockets of empty space where the Apple Watch packs in sensors and support structures. Jan notes that the Temu device imitates the overall silhouette and even the digital crown placement, yet the underlying architecture is closer to a basic fitness tracker that has been stretched to fill a watch‑sized shell.
In his analysis, Jan points out that the Temu watch relies on cheaper construction choices that would likely affect how it ages on a wrist. The battery appears to have less robust bracing, and some of the internal joints and solder points look rougher and less uniform than those in the Apple Watch scan. A detailed write‑up of the experiment describes how the Temu copycat’s internal supports and seals are comparatively thin, which suggests that the device would ultimately deteriorate over time under the same daily wear that the real Apple Watch is designed to survive, a conclusion drawn from the way the Temu watch is put together.
What CT scans reveal about safety and longevity
Looking at the two scans side by side, the most striking difference is not just how much more is inside the Apple Watch, but how that complexity is organized to manage risk. A smartwatch sits directly on skin for hours at a time, so the way its battery is mounted, how its casing is sealed, and where its heat sources sit relative to the back crystal all matter. In the Apple Watch, Jan’s CT slices show the battery encased in a tight pocket with consistent spacing from the outer shell, and the sensor array on the underside appears to be isolated from the hottest components. That kind of internal zoning is exactly what industrial CT specialists look for when they assess whether a design has been optimized for both performance and safety.
The Temu dupe, on the other hand, shows more ad hoc placement, with the battery and board occupying a larger share of the cavity and fewer obvious barriers between them and the outer case. While the scan alone cannot predict a specific failure, it does highlight how cost‑driven designs often sacrifice redundancy and reinforcement that would help a device survive drops, moisture, or thermal stress. Jan’s video walkthrough, particularly the segment where he pauses to “take a look at what separates the men from the boys, the real from the fake,” underscores that point by zooming in on the Temu watch’s rougher internal geometry at around the 35‑second mark of the CT demo, where he contrasts its sparse supports with the Apple Watch’s more intricate skeleton.
Why this matters for anyone tempted by ultra‑cheap wearables
For shoppers, the appeal of a Temu smartwatch that looks like an Apple Watch is obvious: it promises the same aesthetic for a fraction of the price. What Jan’s CT experiment shows is that the resemblance is largely skin deep. The Apple Watch’s dense, deliberate internals reflect years of iteration on things like waterproofing, drop resistance, and sensor accuracy, while the Temu copy leans on a hollowed‑out design that prioritizes hitting a low cost over building in extra safety margins. That does not mean every budget wearable is unsafe, but it does mean that a convincing exterior is not a reliable proxy for the engineering that actually keeps a device working on your wrist.
I see this kind of imaging as a useful reality check in a market flooded with clones and lookalikes. Industrial CT has already been used to compare real and fake Apple accessories, and those scans consistently show that genuine products devote more volume to shielding, structural ribs, and thermal management than their counterfeit counterparts. Jan’s Canadian Apple Watch versus Temu showdown extends that pattern into the smartwatch category, giving consumers a rare, X‑ray‑level view of what they are really buying when they choose a cut‑price dupe over the original. For anyone weighing that decision, the wild CT images are a reminder that the most important differences between devices are often the ones you never see.
