Realme Watch S2

Name: Realme Watch S2
Brand: Realme
SKU: 58171

Manufacturer: Realme

The Realme Watch S2 is a round-faced smartwatch built around a 1.43″ OLED display running at 466 x 466 px with a pixel density of 326 ppi. The watch ships with an always-on display mode and is protected by Gorilla Glass 3, sitting in a 46.5 × 46.5 mm case that weighs just 41 g and measures 11 mm thick. Its 22 mm band is user-replaceable, and the design carries both an IP68 rating and a 5 ATM waterproof rating down to 1.5 m.

On the health and tracking side, the Realme Watch S2 includes a heart rate monitor, a pulse oximeter for blood oxygen readings, and an accelerometer, covering sleep tracking, step counting, pace, distance, and calorie burn. The companion app — which is free and ad-free — supports goal setting, an exercise diary, water intake logging, and weight tracking across 9 recorded exercise types, and requires no account to use. A 380 mAh rechargeable battery is rated for up to 20 days of use, and the watch pairs with both Android and iOS devices via Bluetooth while also offering wrist notifications, call control, silent alarms, and 4 GB of internal storage.

Pros

The AMOLED display delivers sharp visuals at 326 ppi with a 466 x 466 px resolution, and the always-on mode keeps key information visible at a glance
Gorilla Glass 3 protection adds a meaningful layer of durability to the screen for day-to-day use
A 5 ATM and IP68 dual water resistance rating with a 1.5 m depth tolerance makes it suitable for swimming and water exposure
A rated battery life of 20 days from a 380 mAh cell reduces how often the watch needs to be charged
The companion app is free, ad-free, and does not require an account, lowering the barrier to getting started
Covers a broad range of health tracking including heart rate, blood oxygen, sleep reports, step counting, calorie burn, water intake, and irregular heart rate warnings

Cons

No gyroscope, barometer, compass, or cadence sensor limits the accuracy and depth of certain workout and navigation metrics
Multi-sport mode is absent, restricting structured tracking to a narrow set of 9 exercises
Wireless charging is not supported, requiring a physical cable connection every time the battery needs topping up
No NFC, Wi-Fi, or cellular connectivity means the watch is fully dependent on a paired smartphone for most functions
Cannot be used to answer calls directly from the wrist despite having call control
The app does not support route mapping, calendar sync, music playback, or personalisation, which may feel limiting for users seeking a more integrated experience

Who is this for?

The Realme Watch S2 is a solid fit for everyday users who want reliable health and activity monitoring without added complexity. Its heart rate tracking, blood oxygen monitoring, and sleep reporting make it well-suited for people who want to keep tabs on their general wellness throughout the day. The 5 ATM and IP68 water resistance means it holds up comfortably for swimmers or those who wear their watch in wet conditions regularly. With a 20-day battery life and a free, account-free companion app, it also works well for users who prefer low-maintenance wearables that stay out of the way.

Who is this NOT for?

Users who rely on precise workout data will find the watch limiting, as it lacks a gyroscope, barometer, compass, and cadence sensor, and does not offer multi-sport mode or elevation tracking. Athletes or outdoor enthusiasts who need detailed route navigation or structured training support across a wide range of disciplines will quickly outgrow its 9-exercise catalog. Similarly, users looking for a more connected experience — such as on-wrist call answering, NFC payments, or music playback — will find those capabilities absent, making it a poor match for anyone expecting a full-featured smartwatch experience.

Final Verdict

The Realme Watch S2 presents itself as a capable daily wellness tracker that covers the essentials without overreaching. Its sharp AMOLED display, solid water resistance, and broad health monitoring — from blood oxygen and heart rate to sleep reporting and calorie tracking — give it a well-rounded profile for users focused on everyday fitness and wellbeing. Where it falls short is in depth: the sensor set is limited, multi-sport support is absent, and connectivity options are basic. That said, for anyone seeking a low-maintenance wearable with up to 20 days of battery life and a clean, account-free app experience, the Realme Watch S2 delivers a coherent and practical package that suits its intended audience well.
