This Watch doesn't tick, but it does have some other nifty specs and features:

1.39-inch display with 454 × 454 resolution

4 GB internal storage

Wi-Fi, Bluetooth 5.0, and built-in GPS

IP68 ingress protection, rated for water resistance of up to 50 meters (5 ATM)

Accelerometer, gyro, barometer, compass, heart rate, SpO2

Running on a custom RTOS (Real-Time Operating System)

Come teardown time, there's no hiding from our ProTech Toolkit—not in a box, and not with a fox. We do rather like this foxy red box, though.

But before we start tooling around—let's compare! At left: the Galaxy Watch3, with its rotating dial wheel and tactile buttons. And at right: the Huawei Watch GT2e, with its electronic "rotating" touch-bezel and low-profile buttons (similar to the OnePlus Watch's).

Around back, the OnePlus Watch packs fairly standard equipment heart rate + SpO2 (blood oxygen saturation) sensors—no fancy ECG, like in the Galaxy Watch3 or Apple Watch Series 6.

Standard spring bar pins hold the fluoroelastomer straps in place, so we easily dispatch those, along with four Torx screws on the back of the watch.

Our first peek inside reveals a back cover carrying a Li-ion battery and a few other notable travelers.

A single metal bracket covers the hidden cable connectors, which we'll remove to get a closer view.

All together, this back cover is home to a tiny speaker and linear actuator, a microphone, a barometric sensor, and the heart rate and SpO2 sensors. Most of those parts live on the same flex cable octopus, which is not removable.

The only replaceable part in the bunch is the loudspeaker—if you trust the reading on the other side of the "not removable" battery. Which... we don't. It seemed perfectly removable to us!

The power cell delivers 1.59 Wh (410 mAh @ 3.87 V). That puts it above the Galaxy Watch3 (1.3 Wh) and the Apple Watch Series 6 44 mm (1.17 Wh). Only the Xiaomi Mi Watch from 2021 provides more juice with 1.62 Wh.

Moving on—only a few Phillips screws hold the motherboard in place, which does not seem to have anything mounted on this side.

So let’s pop off those remaining display and button connectors, and then go for the brainnnnnnnns.

Geomagnetic Sensor (likely)

With the motherboard out and this intricate button liner removed, we focus on the last part—the screen.

We apply some heat and flex our cutting skills until we can finally slice that show-off… off.

With that, our teardown is over. Where did the time go? We seem to have lost track.

Please feel free to admire this timepiece's pieces. And while we work on reassembling it, here are some repairability observations for you to ponder.
