Last week, OnePlus strongly hinted that it would be launching the OnePlus Watch along with three new models. And now, courtesy of Unbox Therapy, we have our first look at the OnePlus Watch.

If you doubt the authenticity of this image, you really shouldn't. Because the official OnePlus account shared this tweet and added, "We'll show you a lot more on March 23." This is the same day that OnePlus will announce its lineup of OnePlus 9 phones.

At first glance, you might think you're looking at pictures of Samsung's Galaxy Watch Active 2. Both share the same round face, a rubber strap that fits over itself, and two buttons on the right hand side. Importantly, the strap does not appear to be proprietary. This means that it will likely be customizable without having to purchase official OnePlus accessories.

This is also a very limited first insight into what the OnePlus wearable OS will look like; responding to a direct question on the OnePlus forum, CEO Pete Lau said that it will use RTOS (real-time operating system) instead He stated.

"We think we can cover some of the biggest concerns we hear from people looking to buy a smartwatch and provide a smooth, reliable experience while offering excellent battery life," Lau explained.

While one shouldn't read too much into the watch face image, the colored bars around the time may indicate activity levels, similar to the activity ring on the Apple Watch.

And from the reveal earlier this week, it seems certain that OnePlus is going after the fitness crowd hard with a feature set that includes automatic workout detection, heart rate monitoring, and blood saturation tracking.

According to leaker Ishan Agarwal, the OnePlus Watch is "loaded, at least in terms of workout features," which hopefully means the inclusion of built-in GPS, but given that the company has promised an "affordable" price, that may be off the table.

While the leaked information doesn't point to anything particularly groundbreaking, there is one area where the OnePlus Watch could stand out against the best smartwatches: while Agarwal won't give us full battery statistics, OnePlus' ultra-fast Warp Charge technology, which he said allows for "a week of charging in 20 minutes."

Still, if the charging is fast, the watch performs well, and the price is competitive, as OnePlus suggests, the company's first wearable could be really attractive.
