Withings Scanwatch Nova Heart Health Hybrid Smartwatch - Long Battery

In this review the Withings Scanwatch Nova is presented as a health-first hybrid smartwatch for people who want medical-grade monitoring in a classic watch body; the single biggest reason to buy is its extensive health tracking suite packed into a design that still looks like a traditional timepiece. The reviewer found it especially suited to users focused on heart and sleep metrics, with clear wearable comfort and an unusual 30-day battery life that removes daily charging hassles while keeping continuous monitoring active.

Key Features

• Heart rate tracking: Continuous 24/7 heart rate monitoring with alerts for unusually high or low rates helps users spot potential issues and optimize workouts.
• Respiratory and SPO2 monitoring: Blood oxygen and respiratory metrics run in the background and during sleep to provide additional context for overall cardio-respiratory health.
• Menstrual cycle guide: Cycle logging for period duration, symptoms and moods helps women track patterns and plan routines over time.
• Sleep tracking: Detailed sleep staging, disturbances and a Sleep Quality Score offer actionable insight to improve daily energy and recovery.
• Long battery life: Up to 30 days on a single charge means continuous tracking for weeks without needing daily charging, with a supplied USB-C docking station.
• Durable hybrid design: A diver-inspired, high-end watch case houses the sensors so the device reads as a premium wristwatch while providing medical-oriented tech.

Who It's For

The Scanwatch Nova is aimed at users who want serious health monitoring without wearing an obvious fitness band: people who value continuous heart rate, SPO2 and sleep data delivered in a classic watch form. It suits active users who also want automatic activity detection across many workouts and the ability to review trends in an app on iOS or Android.

It is less suited to buyers who need a large color display with third-party apps or those who expect smartwatch-centric features like extensive on-device apps and widgets. If you want a touchscreen social-smartwatch experience, this hybrid design and focus on medical and sleep metrics may feel limited.
