Code found in Samsung's Wearable app suggests the company is preparing a second smartwatch beyond its premium Wear OS lineup, and the leak indicates it could skip Google's platform entirely for dramatically better endurance. References discovered by SamMobile list the device under the codename "Samsung Galaxy Aero" alongside the code "galaxy_rtos_watch," pointing to a real-time operating system rather than Wear OS.
The timing is notable since Samsung recently unveiled its latest premium smartwatches, including the Galaxy Watch 9 series and the flagship Galaxy Watch Ultra 2. That positioning suggests the Galaxy Aero could target a lower price tier, since an RTOS watch would not need the expensive processor, large memory, or high-capacity battery found inside its premium Wear OS models, giving Samsung more room to compete against affordable watches and fitness trackers from brands like Amazfit and Motorola.
RTOS watches commonly last a week or more between charges, while most Wear OS models still need charging every day or two, and lower power consumption could push the Galaxy Aero toward several weeks of use. Because dozens of RTOS versions are in circulation, it remains unclear whether Samsung is using an open-source system like FreeRTOS or developing a proprietary real-time operating system.
The trade-off for that battery life would likely come in the software experience. An RTOS-based Galaxy watch would probably depend on Samsung's own health tools, watch faces, and built-in apps, with third-party app support potentially limited and notifications offering fewer ways to reply or interact.
That could make the Galaxy Aero essentially a watch-shaped fitness band, unless Samsung is developing something more advanced.
Early hints of the smartwatch can already be found in the code of the Galaxy Wearable smartphone app, though no further details are known about the features, launch date, or price of the unannounced Galaxy Aero as of now.
