Smartwatches

A smartwatch is chosen first by the phone it pairs with, since some features only work with one operating system. Next come battery life, which ranges from a day to several weeks depending on the screen and sensors, and the comfort of a strap worn day and night. Long lists of sports modes look impressive, but most people only use a handful.

What we rate in this category

Every product in the category is rated from 0 to 100 on these criteria : the same for all of them, whichever merchant sells it.

Read the full method
Display
This criterion measures screen size: the longer the bar, the roomier and easier the display is to read.
Battery life
This criterion measures battery capacity: the longer the bar, the longer the watch lasts between charges.
Speed
This criterion measures processor power: the longer the bar, the faster the watch reacts and runs apps without lag.
Price
This criterion compares the price found to that of other smartwatches on the market.
Build
Resistance to daily use: build quality, moving parts and how it holds up over time.
Capacity
What the appliance holds or handles at once: litres, kilos, cups between two refills. The longer the bar, the more it takes.

Price brackets by tier

Orders of magnitude, not displayed prices: a price only appears on Kalyneo once it has been collected from a merchant, with its collection date.

Under €90

A basic screen and simple activity tracking, with limited sport modes and only modest water resistance.

€90 to €300

The display gets sharper, battery life covers several days and water resistance allows real swimming sessions.

Over €300

Screen and responsiveness reach their best level, with comfortable battery life and more accurate sensors.

The buying guide for this category Buying guide: how to choose a smartwatch Between two smartwatches, the real difference comes from battery life, processor speed and water resistance, far more than the case design. Comparing these scores avoids paying for a spacious display attached to a battery that barely lasts a day. Read the guide
