Our take on the Apple Watch Series 12 (Gris, Aluminium, 42 Mm, Correa Deportiva Navyblau M/L) Mje94zr/A

The Apple Watch Series 12 is Apple's health-focused smartwatch with a 42 mm OLED touchscreen and Wi-Fi/GPS. It tracks heart rate continuously, reads HRV every five minutes, logs background pulse every five seconds, and adds a daily Readiness score, sleep and overnight vital-sign data, blood oxygen readings, heart-rate zones and Target Pace for workouts. It suits iPhone owners who want serious health and training data on the wrist rather than a basic step counter. Rivals like Garmin and Samsung offer longer battery life and Android support, but reviewers rate Apple's heart-rate accuracy and app ecosystem as the class of the field.

About the Apple Watch Series 12 (Gris, Aluminium, 42 Mm, Correa Deportiva Navyblau M/L) Mje94zr/A

The Apple Watch Series 12 is a smartwatch with a 42 mm gray aluminum case and a navy blue Sport Band in size M/L. It has an OLED touchscreen and runs on the S11 chip. Improved optical and electrical sensors record heart rate at shorter intervals.

It tracks heart rate in the background every five seconds and checks heart rate variability every five minutes, which gives data on stress, recovery and sleep quality. The Vitals app shows overnight health data, and the watch can measure blood oxygen saturation. Apps such as Cycle Tracking and ECG add to its health features. A Readiness score is calculated each morning from recent activity, vitals and sleep, then adjusted through the day.

For workouts, it offers advanced metrics, Pace Target, Heart Rate Zones and a more accurate pedometer. Workout Buddy recommendations use Apple Intelligence on a paired iPhone. Fall detection and crash detection can call emergency services, share your location with them and alert the contacts you have chosen. This GPS model works with your iPhone or a Wi-Fi network to send messages, answer calls, play music, use Siri and show notifications.

Questions and answers

Is the Apple Watch Series 12 worth it over the Series 11?
The Series 12 adds short-interval HRV readings, the Readiness score and overnight vital-sign tracking. If you already own a recent Apple Watch and don't care about recovery metrics, the upgrade matters less.
How long does the battery last?
Apple rates it for roughly a full day of use, and sleep tracking means you will usually charge it daily. Heavy GPS workouts drain it faster.
Does it work with Android phones?
No. The Apple Watch Series 12 pairs only with an iPhone.
What is included in the box?
The watch, a Sport Band in the size you choose, and a magnetic charging cable. A power adapter is not included.
Can it measure blood oxygen?
Yes, it takes blood oxygen readings, though like all wrist sensors it is not a medical-grade measurement.
What size is the screen?
The 42 mm model has a 374 x 446 pixel OLED touchscreen.
