Just a few months later, OnePlus launched the smaller Watch 3 43mm, which not solely reduces the show measurement however tweaks the design, making it extra elegant and female (for lack of a greater phrase).
Lately, OnePlus was form sufficient to ship me this smaller watch to take a look at.
There’s not a lot level in doing an in depth overview of this, as it’s functionally the identical because the very good OnePlus Watch 3. I’ll as a substitute deal with the variations, which embrace the general look, battery life, and a few lacking options.

Key Variations
- The 46 mm mannequin makes use of higher-end supplies (titanium and sapphire) and is bigger and heavier.
- The LTPO AMOLED show on the 46 mm is larger and far brighter (as much as 2200 nits).
- Battery life on the 46 mm is considerably longer, particularly in energy saver mode.
- The 46 mm introduces ECG, wrist temperature, and arterial stiffness well being options, with MIL-STD-810H sturdiness and a number of environmental stress assessments that the 43 mm mannequin lacks.
- Each fashions run Put on OS and assist the identical suite of good and exercise options, although the 46 mm mannequin is a step up for well being monitoring and ruggedness.
Dimension Comparisons
The 43mm mannequin is 43.2 x 43.2 x 11 mm whereas the 46mm mannequin is 46.6mm x47.6mm x 11.75mm mm.
The 43mm weighs 37.8g and the 46mm mannequin weighs 49.7g, each excluding straps.
OnePlus states that the 46mm mannequin matches wrists measuring 140-210mm, however doesn’t checklist the dimensions for the smaller mannequin.
Design Comparability

Greater than dimensions have been tweaked for this smaller mannequin; the 46mm mannequin is a chunkier and extra rugged design general, with a bigger crown and quantity bezel giving it a bit extra of a pilot watch type.


The 43mm mannequin is extra appropriate however maybe a bit extra boring. It’s a gorgeous watch, however it’s mainly only a round face with a small crown. The watch strap design has modified a bit and is each thinner at 18mm and doesn’t flare out into the physique of the watch, which provides to the general impression of a smaller watch.
I’ve very slim wrists myself, and I by no means was once keen on outsized watches, however I personally want the 46mm mannequin. Greater than something, I believe design has a bit extra character than the 43mm mannequin.
That being stated, I believe they each look nice, and it’s all down to non-public choice.

Battery Life
The battery life on the OnePlus Watch 3 43mm is excellent for a WearOS watch, simply not so good as the 46mm mannequin.
The official specs point out that the 46mm mannequin ought to final 5 days with regular use or 3 days of heavy use, and from my expertise, that was about proper. A colleague has purchased one and has been raving in regards to the battery life, it is among the defining options of the watch.
As you’d count on, the smaller design of the 43mm means a smaller battery and shorter life. The official specs point out 60 hours of use, so 2.5 days, or 36 hours of heavy use. Once more, this appears correct. I would even squeeze three days of use out of mine.
Three days’ battery life is completely acceptable for a smartwatch, and prior to now I might have classed this as excellent, however the 46mm steals the glory.
In Use
The general expertise of this watch is generally the identical because the 46mm mannequin, so I received’t go into a lot element right here.
I discover it an easy watch to get together with. It’s nice at health and well being monitoring, and I used to be very impressed that these two watches have working energy, a complicated working metric that was once reserved for premium-priced sports activities watches.
One omission of the 43mm mannequin is the ECG performance. I personally don’t thoughts. Whereas it’s good to have these extra options, I at all times discover I exploit them a few occasions and overlook about them. Sensible watches are hardly ever very correct for issues like this; the outcomes are tough to interpret, and there may be not a lot want for a daily ECG except you have got a coronary heart situation, and in case you do, you must most likely spend money on a extra dependable system.
Equally, there is no such thing as a wrist temperature, that is one other function I don’t use a lot, however it’s arguably extra helpful for most people, as it might probably be an early warning signal for being unwell.
Worth and Different Choices
The OnePlus Watch 3 43mm has an RRP of £269. On the time of writing on the 8th of October, the OnePlus web site had it discounted to £229, and there was a £30 assured trade-in choice, albeit with a restricted number of watches you’ll be able to commerce in.
The larger Watch 3 has an RRP of £319 and was out there for £249.
Amazon has the 43mm mannequin listed for as little as £175 for the silver mannequin, which I’ve, or £182.59 for the black mannequin, and the 46mm mannequin for £ £199.59.
Total
I really like the 46mm OnePlus Watch 3, and the brand new, smaller mannequin is generally the identical, so I, due to this fact, love that as nicely.
Clearly, the primary cause why you’d get this over the bigger mannequin is for the aesthetics. Whether or not you have got smaller wrists or usually want the slight design distinction of the 43mm mannequin.
There are a number of caveats with this smaller mannequin. Whereas the battery life is nice, I really like the comfort of longer-lasting watches, and for me, it is a huge think about my shopping for choices. Then, the much less rugged design additionally has a much less sturdy design with no Sapphire crystal cowl glass and no MIL-STD-810H sturdiness. I’ve had no points with the 43mm getting scratched but, however in case you are a really energetic (or clumsy) individual, I believe it’s price contemplating.
Lastly, there may be the shortage of an ECG and wrist temperature, which I’m not too fussed about, however it’s nonetheless good to have the choice there.
Because of the small value distinction, I’d say the 46mm mannequin is the superior watch, offering better bang to your buck. If you’re on the fence about which mannequin to get, I’d advocate leaning in the direction of the 46mm mannequin.
Nonetheless, in case you assume the 46mm mannequin might be too huge, or don’t like its extra rugged aesthetic, then I can completely advocate the OnePlus Watch 3 43mm, it’s an impressive good watch.
