Rogbid launches new AMOLED smartwatch with pressure-based BP system and TI health chip
Rogbid's Rowatch D3 is a new health-focused smartwatch that brings a revised blood-pressure system and updated sensor hardware to the company’s lineup, post the launch of the Titan V earlier this November. The device centers its feature set around pressure-based readings, ECG capture and expanded optical tracking, while keeping the overall design close to recent smartwatch norms.
The watch uses a 1.56-inch AMOLED display (480×480), which is the main interface for health data. The right side houses a rotating crown, a dedicated ECG touch area and a shortcut key that opens the blood-pressure function. Internally, Rogbid has shifted to a sealed airbag system paired with a Murata piezoelectric micro-air pump. The company claims that this enables controlled inflation and deflation for the BP readings, alongside stable airflow and reduced leakage. How this performs in daily use will depend on wrist fit and user movement, since pressure-based wrist readings typically vary under real-world conditions.
For ECG capture, the D3 uses Texas Instruments' AFE4950 chip, which supports synchronized PPG and single-lead ECG. Conductive ECG glass and side electrodes are placed around the frame to complete the circuit. Rogbid claims millisecond-level signal capture, though again, real-world precision will rely on user posture and skin contact. A four-channel optical module handles heart-rate and blood-oxygen measurements, and the watch includes a quick "Mini Health Check" that compiles basic readings (HR, BP, SpO₂, temperature and stress) in roughly half a minute. The D3 is compatible with Android devices running version 8.0 or later and iPhones running iOS 13.0 or later.
Outside health tracking, the smartwatch covers features such as sleep monitoring, multiple sport modes, Bluetooth (5.3) and NFC access (regional support may vary). Battery capacity is listed at 400mAh, with a claimed standby time of up to 15 days. Strap options include silicone and leather variants across five colors. Rogbid has priced the Rowatch D3 at $139.99 on its official store. As part of the launch, customers receive a free pair of earbuds valued at $29.99.
