Oppo has confirmed full specifications for the **Oppo Watch S2** ahead of its official unveiling on **September 22, 2026**, revealing an ultra-thin design and a new “FatMax” fat-burning mode aimed squarely at fitness-focused buyers, [Gizmochina reports](https://www.gizmochina.com/2026/09/16/oppo-watch-s2-specs-confirmed-ahead-of-september-22-launch-8-9mm-thick-fatmax-fat-burning-mode/).

## Oppo Watch S2: Design and Build

The Watch S2 measures just **8.9mm thick** and weighs **34.4g** without the strap, keeping it in line with Oppo’s push toward slimmer wearables that started with the original [Oppo Watch S](https://technosports.co.in/oppo-watch-s-thin-really-thin-debuts-oct-16/). It retains the round dial look and will launch in Vibrant Orange, Misty Powder, and Mountain Shadow Grey colourways.

## Battery Life and Health Tracking

Oppo is promising up to **10 days** of battery life on a single charge, dropping to roughly 7 days with normal use and around 4 days with the always-on display active. On the health side, the Watch S2 packs ECG monitoring, a wrist temperature sensor, blood oxygen tracking, and continuous heart rate monitoring, with Oppo claiming 98.8% exercise heart-rate accuracy thanks to an optical sensor that handles interference 75% better than before.

## FatMax Mode and Connectivity

The headline software feature is **FatMax**, a fat-burning mode that calculates a personalized heart rate zone and tracks fat burn in real time during workouts. The watch also supports dual-device pairing and Watch Fluid Cloud, which surfaces live updates for food delivery, ride-hailing, and navigation directly on the wrist — a feature set that builds on what Oppo introduced with the [Oppo Watch X2](https://technosports.co.in/oppo-watch-x2-launched-premium-smartwatch/).

## Price and Availability

Oppo hasn’t announced India pricing yet, but the original Oppo Watch S launched at 1,499 yuan (roughly €259) in China, giving a rough sense of where the S2 could land. A global rollout typically follows the China launch by a few weeks, alongside other Oppo devices like the recently confirmed [Oppo Reno 16 series](https://technosports.co.in/oppo-reno-16-reno-16c-india-launch/).
