Smartwatches / Withings
Withings ScanWatch Nova Brilliant (39mm)
A month of battery, an ECG and real watch hands — with no apps and no on-board GPS.
Overall score 6.4/10
Pros
- + Works identically on iPhone and Android — no ecosystem trap at all
- + A month per charge versus a day for Apple and Samsung
- + Sapphire crystal, steel bracelet and Super-LumiNova on a watch that also runs an ECG
- + No subscription is needed to see any health metric
- + Two-year warranty
Cons
- − No app ecosystem whatsoever — notifications and a greyscale sub-dial are the entire smart layer
- − No on-board GPS: workouts borrow your phone's location, so you must carry the phone
- − $599.95 is Apple Watch Ultra money for a watch that cannot run a single third-party app
- − Withings' own page says 35 days and the Amazon listing says 30 — the maker's own claim is inconsistent
- − The Amazon ASIN here is the gold two-tone variant; confirm the finish before buying
Withings ScanWatch Nova Brilliant (39mm) review: what the specs say
A month of battery, an ECG and real watch hands — with no apps and no on-board GPS. At $599.95, Withings's 2025 model sits at the premium end of the category — the smartwatches we compare run from $79.99 to $799. It scores 6.4/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Battery Life at 9.6/10 — real endurance between charges, judged against what the claim actually assumes rather than the headline number. The weakest is App Ecosystem at 2.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: no app ecosystem whatsoever — notifications and a greyscale sub-dial are the entire smart layer; and no on-board GPS: workouts borrow your phone's location, so you must carry the phone. Every specification on this page comes from Withings's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Phone Compatibility | iOS and Android both fully supported — this is one of only three watches here that does not punish you for your phone choice. Nothing is gated to a Withings-branded handset because Withings does not make phones. |
| Claimed Battery Life | 720 hrs |
| What the Battery Claim Assumes | Sources conflict: Withings' own US shop page states 'up to 35 days'; the Amazon listing title states '30-Day Battery Life'. Either figure assumes the tiny greyscale sub-dial rather than a colour touchscreen, connected GPS (borrowing the phone's radio rather than its own), and no continuous SpO2. The 720 hours recorded here is the conservative 30-day reading. |
| Case Size | 39 mm |
| Display | Analogue hands over a small greyscale OLED sub-dial — there is no colour touchscreen |
| Operating System | Withings proprietary firmware (no third-party OS) |
| Third-Party Apps | None. There is no app store and no third-party apps — the watch shows a small greyscale sub-dial and notifications only. This is a health instrument in a dress-watch case, not a smartwatch platform. |
| Health Features Enabled in the US | ECG with AFib detection, SpO2, 24/7 wrist temperature, respiratory scan, sleep staging with HRV, and cycle tracking — all available in the US. Withings' ECG holds regulatory clearance; the blood-pressure device Withings sells (BPM) is a separate cuff product, not part of this watch. |
| Subscription Wall | Withings+ is optional and includes a one-month trial. All baseline health data — ECG, SpO2, temperature, sleep score — is available without paying. Withings+ adds programmes, deeper reports and coaching. |
| LTE Option | No LTE variant exists; the watch has no cellular radio and no standalone GPS. |
| Water & Dust Rating | 5 ATM (50 m), swimproof |
| Battery Replacement | Withings sells the watch as a sealed unit; there is no published consumer battery-replacement service, but at 30+ days per charge the cell sees a fraction of the cycles of a daily-charge watch. |
| Connectivity | Bluetooth Low Energy, Connected GPS (uses the phone's GPS) |
| Material | Stainless steel case and bracelet with sapphire crystal and Super-LumiNova hands |
| Warranty | 24 months |
