Apple offers three “smart” watches in its catalog: Apple Watch Series 3, Apple Watch SE and Apple Watch Series 7. Although the Series 3 is the cheapest, it is a model that has been available for several years and no longer receives software news. (so we don’t really understand why Apple continues to sell it). So if you are looking for a smartwatch from the bitten apple, it is better to opt for an SE or a Series 7. But which one? We put them face to face.

size and screen– Apple Watch SE and Apple Watch Series 7 are available in two sizes. Their dimensions are almost identical. the big difference is on the screen. The Series 7 is larger because the edges have been further reduced, and in the 45mm version it is almost two inches. This is also ODA (Always on displayalways on), a function that is not available on the OS.
-
Materials: While the SE is only available in aluminum, the 7 series is also available in stainless steel and titanium; Of course, its price is much higher. Both of these materials are more durable, which is something to keep in mind if you’re a little clumsy or tend to bump the watch inadvertently.
-
Processor: The Apple Watch Series 7, in theory, is faster than the SE, although it is very likely that the performance difference is so small this goes unnoticed by the user, although the SE should receive fewer software updates than the 7 series. Both models have 1 GB of RAM and 32 GB of internal storage to install applications or save music , audiobooks or offline podcasts.
-
sensors: The Apple Watch Series 7 has more and better sensors, such as the 3rd generation heart rate sensor or the measurement of SpO2 and VO2max. With this model it is possible perform ECG measurementsthat is, from an electrocardiogram, although its results should not be considered 100% reliable.
-
Drums: The battery of the SE and the Series 7 is very similar, but the latter has a very interesting advantage: a faster loading which allows you to be 100% in much less time, ideal for problems and low loads.
-
Price: Price is always a big factor, and between the Apple Watch SE and the Series 7, there’s a considerable difference of just over 100 dollars (or more, depending if you’re looking for a more stylish/durable model).
Apple Watch SE and Apple Watch Series 7, which one to buy?

The Apple Watch Series 7 is the most complete “smart” watch in the company’s catalog and with improved functions compared to previous generations. However, the ECG for electrocardiograms or always-on display function they may not be defining characteristics for some users.
That’s why if you’re going to use the smartwatch to receive wrist notifications and record sports training, don’t worry too much about your heart rate sensor not being as accurate as the Series 7 because it’s possible to connect via Bluetooth a chest heart rate monitor to get more reliable measurements.
This lack of features also affects the price: the Apple Watch SE is significantly cheaper than the Series 7. And unless you want those extra millimeters of screen yes or yes, apart from the functions mentioned above, the Apple Watch SE is a “smart” watch with a lot of war to give.
