The wearable is the Suunto 9 Peak Pro, an improved version of the original Suunto 9 Peak that the Finnish brand launched last year
Aside from the impressive battery, the Suunto 9 Peak Pro is expected to have the same thin and premium design, including a stainless steel body and sapphire crystal protection
The touch-sensitive display is said to still measure 1.2 inches, but users can use the same navigation buttons on the right.
More importantly, along with the health and fitness features, fans could also see new colors and watch faces with the new smartwatch.
The leak suggests that the Suunto 9 Peak Pro could go on sale for €499. That would be slightly more expensive than the Suunto 9 Peak's current price of €469 in the eurozone
It is expected that Suunto will also lower the US list price of the Suunto 9 Peak once the Pro version is officially announced.
The longer runtime could be due to a larger battery capacity or a more efficient wearable chipset
The smartwatch is also unlikely to be equipped with Wear OS as its predecessor runs on Suunto's own operating system
As a reminder, only the Suunto 7 Peak was launched using Google's wearable platform.
