Critics & buyers

What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Stainless steel build looks and feels premium, reads as a traditional analog watch on the wrist
- Clinically validated ECG and SpO2 sensors, with FDA and CE approval; health data can be exported and shared with medical professionals
- Battery life reaches two to four weeks in real-world use, far exceeding most smartwatches
Reviewers push back
- No built-in GPS; outdoor route tracking requires a paired phone
- Vibration motor is weak — alarm and notification haptics are easy to sleep through or miss entirely
- App is underdeveloped: confusing layout, limited workout analytics, and the Android version has caused significant battery drain on phones
A handsome hybrid watch with clinically validated health sensors and remarkable battery life, held back by weak haptics, a limited app, and no built-in GPS.
Battery life estimate divides reviewers: some found the 30-day claim realistic with careful use, others consistently landed closer to two to three weeks
