Rogbid has introduced the Rowatch D3, a health-oriented smartwatch featuring an upgraded pressure-based blood-pressure system and Texas Instruments’ AFE4950 ECG chip. The model follows the Titan V released earlier in November and retains a conventional smartwatch design while adding more advanced biometric tracking.
The Rowatch D3 includes a 1.56-inch AMOLED display with a resolution of 480×480. The right side of the watch features a rotating crown, a dedicated ECG touch area and a shortcut button for blood-pressure measurements. Rogbid said its revised BP system uses “a sealed airbag system paired with a Murata piezoelectric micro-air pump,” allowing controlled inflation and deflation for readings. The company noted that performance may still vary depending on wrist fit and user movement, a common limitation for wrist-based pressure systems.

For ECG monitoring, the watch integrates TI’s AFE4950 chip, which supports synchronized PPG and single-lead ECG capture. Conductive ECG glass and electrodes around the frame complete the circuit. Rogbid claims the hardware enables millisecond-level signal acquisition, though accuracy in daily use will depend on posture and skin contact. A four-channel optical sensor handles heart-rate and blood-oxygen tracking, and a Mini Health Check feature can compile HR, BP, SpO₂, temperature and stress data in roughly 30 seconds.
Beyond health features, the Rowatch D3 offers sleep monitoring, multiple sports modes, Bluetooth 5.3 and NFC access, though NFC availability varies by region. The watch carries a 400mAh battery with an estimated standby time of up to 15 days. It supports Android 8.0 and later as well as iOS 13 and newer.
