The Samsung Galaxy Watch series represents a collection of smartwatch devices engineered and manufactured by Samsung Electronics. This lineup integrates numerous health, fitness, and style-oriented functionalities, aligning closely with Samsung's broader Galaxy ecosystem. It follows as the successor to the earlier Samsung Gear smartwatch range.

The inaugural device in this collection, known simply as the Galaxy Watch, debuted in August 2018.[1]

Maintaining the circular design characteristic first seen in the Samsung Gear S2 and Samsung Gear S3, the Galaxy Watch series shares many operating system functionalities with these predecessors.

Operating system

Samsung utilized its proprietary Tizen OS for the original Galaxy Watch, as well as for the Watch Active, Active2, and Watch3 models. This OS was also employed in the former Samsung Gear devices.

In August 2021, Samsung announced the Galaxy Watch4 and Galaxy Watch4 Classic, marking a collaboration with Google to adopt Wear OS[2]. This partnership brought select features from Samsung's Tizen combined with One UI Watch into Wear OS, while some functionalities remained exclusive to Samsung’s customized version of this otherwise closed-source platform.

Galaxy Watch

The entry-level offerings in the Galaxy Watch lineup originated from the more affordable Galaxy Watch Active series. Unlike the original Galaxy Watch and Galaxy Watch3 models, these lacked a rotating bezel,[3] emphasizing fitness and wellness tracking. By the fourth generation, Samsung removed the "Active" branding as this form factor became the standard across their smartwatch offerings.[4] The Galaxy Watch FE model released in 2024 was based on the Watch4 framework.

With the launch of the Watch5 model, Samsung introduced a temperature sensor alongside fast charging capabilities.

The subsequent Watch6 enhanced battery life and increased RAM capacity.

The latest Watch7 featured expanded storage, upgraded sensors, and support for accelerated charging.

Among all models, only the Watch5 Pro and Watch Ultra support GPX routing and retain bezel rotation functionality.

Galaxy Watch Classic

The Galaxy Watch Classic series succeeds the Samsung Gear S2 and S3, retaining the rotating bezel feature first introduced with the Gear S2. It served as the primary smartwatch model for the first and third generations of the Galaxy Watch lineup. Notably, the classic edition was absent in the second generation. From the fourth generation onward, this original design was elevated to a more premium tier within the collection. Both the Watch4 Classic and Watch6 Classic maintain the rotating bezel as an optional method for navigation. In contrast, the Watch5 Pro and Watch Ultra models do not include this feature. Additionally, neither the fifth nor seventh generations offer a Classic version of the smartwatch.

Galaxy Watch FE

The Galaxy Watch FE (short for "Fan Edition") represents a more affordable smartwatch option. This initial Galaxy Watch FE model draws heavily from the Galaxy Watch4, with the primary physical distinction being the replacement of Corning Gorilla Glass DX+ on the Watch4 with sapphire crystal glass on the FE version.
