OnePlus Claims 43mm Watch is the Perfect Size Outshining Competitors

OnePlus Watch 3: A Smaller Option for Smartwatch Lovers
The OnePlus Watch 3 has made a splash as our top pick for Android smartwatches. However, it comes with one notable drawback: its size.
To be more specific, the watch is only available in a single size of 47mm. While this may appeal to those who prefer larger devices, it leaves out potential buyers who are looking for something more compact.
Moast leading smartwatch brands offer their products in two different sizes, giving customers the adaptability they desire. Recognizing this gap, OnePlus has responded by launching a smaller version of the Watch 3 that weighs just 37.8g and measures 43mm.
This new model is lighter and more comfortable than its larger counterpart but still doesn’t match the lightweight feel of competitors like the Google Pixel Watch 3 (31g), Samsung Galaxy Watch 7 (28.8g), or Apple Watch Series 10 (29.3g-34.4g depending on configuration).
OnePlus mentioned that they could have created an even smaller version but chose not to do so. We had a chat with Aske Kjaer, EU PR Product Lead at OnePlus, to understand their reasoning behind this decision.
The Ideal Size: finding Balance
Kjaer explained that “the dual engine architecture requires space since we’re using two chipsets.” He emphasized that they wanted to ensure there was enough room for an effective sensor suite as well.
While the new OnePlus watch 3 in its smaller form lacks the ECG monitor found in its bigger sibling due to space constraints, it still includes all other essential sensors.
A significant challenge when downsizing any smartwatch is maintaining screen usability without making it too small or tough to interact with. To avoid this issue, OnePlus decided against reducing the display below its current size of 1.32 inches as anything smaller might become “finicky,” according to Kjaer.
“When you put all these factors together,” he added, “43mm really hits that sweet spot.” This balance allows users to enjoy features like notable battery life—60 hours in smart mode and up to seven days when using power-saving mode—though itS slightly less than what’s offered by the larger variant.
A Closer Look at Features
The main trade-offs between the two sizes include screen dimensions and battery longevity along with missing ECG monitoring capabilities on the smaller model.
Despite these compromises, I found during a preview event that navigating through menus on this watch felt smooth thanks to its well-proportioned display; plus, if those minor limitations don’t bother you much and you're after something compact yet functional—the benefits may outweigh them entirely!
