Description
TITANIUM DESIGN · ADVANCED SENSOR PLATFORM
An advanced sensor concept, built into a titanium ring.
The BKWAT V80 is a supplier-listed ECG and electrodermal-activity (EDA) smart ring with a titanium exterior. Its feature set brings together ECG, EDA, heart rate, HRV, blood oxygen, sleep analysis, blood pressure and activity tracking in a compact ring format.
The manufacturer lists a Nordic 54L15 platform, a Texas Instruments TI4850 analog front end, Bluetooth 5.3 LE, a 16–24mAh battery range and 4–7 days of normal use. The V80 is positioned as an advanced health-feature ring; clinical performance and US regulatory status are not established by the supplied sheet.
Key Features
- ECG and EDA: Manufacturer lists electrocardiogram and electrodermal activity monitoring functions.
- Heart rate and HRV: Manufacturer-listed heart-rate and heart-rate-variability monitoring.
- Blood oxygen: Manufacturer-listed SpO₂ feature.
- Sleep analysis: Supplier lists a midnight–6am (00:00–06:00) sleep pattern analysis window with updates every five minutes, and separately lists 24/7 scientific sleep monitoring.
- Blood pressure: Manufacturer-listed blood-pressure measurement feature; evidence and intended medical use require separate review.
- Sports and remote functions: Supplier-listed sports mode, remote shutdown and touch-button brightness adjustment.
- Titanium body: Titanium construction with black, silver and rose gold supplier-listed colors.
- 5ATM + IP68: Both ratings appear in the supplier specification; permitted water use needs confirmation.
A distinctive combination of sensing features
ECG and EDA are the headline features in the manufacturer sheet. Alongside HRV and heart rate, these measurements create a different product concept from basic sleep-and-step rings. The supplier has not provided performance validation or US authorization documentation.
Sleep monitoring with stated analysis conditions
The supplier specifies midnight to 6am analysis with five-minute updates, while also using a broader 24/7 sleep-monitoring claim. The final firmware and app behavior should be checked before publishing one unified promise.
A compact titanium platform
The V80 is built around the manufacturer-listed Nordic 54L15, TI4850 analog front end and BLE 5.3. The 16–24mAh battery range and 4–7 day normal-use estimate are configuration-dependent supplier specifications.

FAQ
What does EDA mean?
EDA stands for electrodermal activity, a signal related to changes in electrical properties of the skin. The manufacturer lists EDA sensing, but no validated interpretation accuracy is provided.
Does the V80 support ECG?
The manufacturer lists an ECG feature. The supplied document does not establish clinical accuracy or US marketing authorization for a medical ECG function.
Does it monitor blood pressure?
Blood-pressure measurement is listed by the supplier. This must not be treated as a clinically validated blood-pressure reading without supporting evidence and applicable authorization.
How is sleep monitoring described?
The supplier gives a midnight–6am analysis window with five-minute updates and also uses a 24/7 sleep claim. Verify actual app/firmware behavior prior to advertising a specific coverage level.
