[1] The Galaxy Watch series shares the circular form factor of the Samsung Gear S2 and S3, as a result much of the OS features are shared between the Gear S2 and S3 and the Galaxy Watch.

With the announcement of the Galaxy Watch4 and Galaxy Watch4 Classic in August 2021, Samsung entered into a partnership with Google to work together on Wear OS[2] bringing some of the features from Samsung's Tizen with One UI Watch to Wear OS, while other features remained exclusive to Samsung's own customization to the OS.

With the 4th generation, the "Active" label was dropped in favor of the form-factor becoming the base smartwatch in the series.

For the first and third generation of the Galaxy Watch line, it functioned as the base smartwatch of the series.

The Watch5 Pro and Watch Ultra omit the feature, both the 5th and 7th generation do not have a Classic variant of the smartwatch.
