Both watches are clearly different models given their naming, but they will both share some specs and features. For example both devices are waterproof with a rating of 5 ATM, meaning unless you plan on going deep sea diving for extended periods of time, both smartwatches should be good for use in the pool.
Both watches will also feature an increase of 30% in battery capacity compared to the first model, meaning that it should see an improvement of about 1-2 days on a single charge. Both devices are also powered by Qualcomm’s Snapdragon Wear 2100, and will be running on Google’s Wear OS platform.
Other than that, the main difference between the models would be the size, with the E2 sporting a marginally larger design, while the S2 is slightly smaller and is also offered in white. However both will still feature a 1.39-inch AMOLED 400×400 display. No word on pricing or availability just yet.
