Third-party reviews

What customers like about Oppo Watch S

  • Ultra-slim and lightweight 8.9mm stainless steel design that is comfortable for 24/7 wear.
  • Exceptionally bright AMOLED display, reaching up to 3,000 nits for excellent outdoor visibility.
  • Long battery life, typically lasting 6–7 days with regular use and up to 10–14 days in power-saving mode.
  • Comprehensive health suite including an 8-channel heart rate sensor, 16-channel SpO2 monitoring, and a medical-certified ECG sensor.
  • Unique dual-phone pairing feature that allows receiving notifications from two devices simultaneously.
  • Fast VOOC charging that provides a full day of use from just a 10-minute charge.

What customers don't like about Oppo Watch S

  • Limited third-party app ecosystem compared to competitors using Google's Wear OS or Apple's watchOS.
  • Inability to respond to messages directly from the watch, despite receiving notifications.
  • Sports analysis is considered basic and may not satisfy serious athletes looking for deep professional-grade metrics.
  • Full 3,000-nit screen brightness is often restricted to specific outdoor workout modes to conserve battery.
  • Occasional thermal management issues reported during sustained GPS usage.

Verdict

The OPPO Watch S is an ultra-slim smartwatch featuring a 1.46-inch AMOLED display with a 3000-nit peak brightness, a 464x464 resolution, and a lightweight 35g stainless steel chassis measuring just 8.9mm thick. It is powered by a BES2800BP chipset with 4GB of storage, offering comprehensive health tracking including a 60-second wellness overview, ECG, heart rate, 16-channel SpO2, and skin temperature monitoring. Key advantages include a long-lasting battery of up to 10 days, dual-band (L1+L5) GPS for precise tracking of over 100 sports modes, and unique cross-platform dual-phone pairing. However, it lacks Wi-Fi connectivity and runs on the proprietary ColorOS Watch 7.1, which limits third-party app support and NFC payment functionality compared to Wear OS competitors.
