The Apple Watch SE (2nd Gen) [GPS 40mm] Smartwatch with Midnight Aluminum Case and Midnight Sport Band S/M is made for users who want the core Apple Watch experience without paying for the most expensive model. It focuses on daily fitness tracking, sleep tracking, heart rate monitoring, safety features, notifications, Apple Pay, workout support, and a clean Retina display.
This version is especially suitable for iPhone users who want a smaller and lighter Apple Watch. The 40mm case is compact, the Midnight Aluminum Case looks modern and simple, and the Midnight Sport Band S/M gives the watch a practical everyday style.
Apple introduced the Apple Watch SE 2nd generation in 2022, and Apple’s official technical specifications list the 40mm GPS model at 40mm height, 34mm width, 10.7mm depth, 324 by 394 pixels, 759 sq mm display area, and 26.4 grams weight.
In this review, we will look at its design, display, fitness features, sleep tracking, heart rate tools, Crash Detection, battery life, water resistance, pros, cons, and buying tips.
Product Overview
The product title highlights these key details:
- Product: Apple Watch SE 2nd Gen
- Connectivity: GPS
- Case size: 40mm
- Case material: Midnight Aluminum
- Band: Midnight Sport Band
- Band size: S/M
- Main features: Fitness tracking, sleep tracking, Crash Detection, heart rate monitoring, Retina display, water resistance
This is the GPS model, so it is best for users who usually keep their iPhone nearby. It can track workouts, show notifications, monitor heart rate, record sleep, use Apple Pay, and support many watchOS features. However, it does not offer independent cellular calling or messaging unless your iPhone is nearby or connected.
Apple’s technical specifications say Apple Watch SE 2nd generation requires iPhone Xs or later, including iPhone SE 2nd generation or later, with iOS 18 or later.
That means this smartwatch is mainly for iPhone users, not Android users.
Design and First Impression
The Apple Watch SE 2nd Gen has a familiar Apple Watch design with a rectangular case, curved corners, Digital Crown, side button, microphone, speaker, and optical heart sensor. Apple lists the SE 2nd Gen with an aluminum case available in Midnight, Starlight, and Silver finishes.
The Midnight Aluminum Case is a strong color choice for users who want a clean and versatile look. It is dark, modern, and easy to match with casual outfits, gym clothes, office wear, and everyday fashion.
The Midnight Sport Band also makes sense for daily use. Dark bands usually hide dirt better than lighter bands, and a sport band is practical for workouts, walking, running, sleep tracking, and regular wear.
The 40mm case is one of the biggest reasons to choose this model. It is smaller and lighter than the 44mm version, which can make it more comfortable for smaller wrists or users who do not like bulky smartwatches. Apple lists the 40mm SE 2nd Gen GPS model at 26.4 grams, making it a lightweight option for all-day wear.
Retina Display
The Apple Watch SE 2nd Gen includes a Retina LTPO OLED display with Ion-X front glass, 326 pixels per inch, and up to 1000 nits maximum brightness, according to Apple’s technical specifications.
The display is clear enough for checking time, notifications, workout stats, heart rate, timers, weather, messages, and activity rings. The 40mm screen is smaller than larger Apple Watch models, but it is still practical for daily use.
One important thing to understand is that the Apple Watch SE does not offer all the premium display features found on higher Apple Watch models. For example, users who specifically want an Always-On display may need to consider Apple Watch Series models instead. The SE is designed to provide the essential Apple Watch experience at a more accessible level.
Fitness Tracking
Fitness tracking is one of the main reasons people buy Apple Watch SE. The watch can track a wide range of workouts and daily activity. Apple’s official specifications list workout support for running, cycling, swimming, hiking, walking, elliptical, rowing, stair stepper, HIIT, yoga, functional strength training, dance, core training, Pilates, Tai Chi, kickboxing, wheelchair workouts, multisport, and more.
For daily motivation, Apple’s Activity Rings are simple and useful. They help you track movement, exercise, and standing time. This can be helpful for users who want to build healthier habits without using a complicated fitness system.
The watch can also support running features such as custom workouts, customizable workout views, Heart Rate Zones, Race Route, Pacer, stride length, ground contact time, vertical oscillation, and automatic track detection.
This makes the Apple Watch SE more capable than a basic step counter. It is useful for beginners, casual walkers, regular gym users, and runners who want everyday workout tracking.
Built-In GPS
Because this is the GPS model, it can track outdoor workouts such as running, walking, cycling, and hiking. Apple lists connectivity features including L1 GPS, GNSS, Galileo, and QZSS for the Apple Watch SE 2nd generation.
Built-in GPS is useful because it helps record route, pace, distance, and outdoor workout data. For users who walk, run, or cycle outside, this is an important feature.
However, because this is not the GPS + Cellular version, phone-free communication is limited. If you want to make calls, send messages, or stay connected without your iPhone nearby, you should consider a GPS + Cellular model.
Heart Rate Monitoring
The Apple Watch SE 2nd Gen includes a second-generation optical heart sensor, according to Apple’s technical specifications. It also includes the Heart Rate app, high and low heart rate notifications, and irregular rhythm notifications.
This is useful for everyday wellness awareness. You can check your heart rate during rest, workouts, walks, and other activities. The watch can also alert eligible users if it detects unusually high or low heart rate patterns.
Apple notes that irregular rhythm notifications are not intended for people under 22 years old or for users previously diagnosed with atrial fibrillation.
The heart rate features are helpful, but they should not be treated as a replacement for medical care. If you feel chest pain, shortness of breath, dizziness, fainting, or any unusual symptoms, contact a qualified healthcare professional.
Sleep Tracking
The Apple Watch SE 2nd Gen includes the Sleep app with sleep stages, according to Apple’s official specifications.
Sleep tracking can help users understand how long they sleep and how their sleep may be divided into different stages. This can be useful for people who want to improve bedtime habits, reduce late-night screen time, or build a more consistent sleep routine.
The lightweight 40mm case can be a good advantage for sleep tracking because it may feel more comfortable overnight than a larger smartwatch.
Sleep tracking should be used as a general wellness tool, not a medical diagnosis. If you have serious sleep problems, loud snoring, breathing concerns, or daytime fatigue, speak with a healthcare professional.
Crash Detection and Safety Features
One of the strongest features of the Apple Watch SE 2nd Gen is safety support. Apple lists safety features including Emergency SOS, international emergency calling, Crash Detection, Fall Detection, noise monitoring, and Backtrack.
Crash Detection can be useful in serious car accidents, while Fall Detection can help if the user takes a hard fall. Emergency SOS can help contact emergency services, but Apple notes that Emergency SOS requires a cellular connection or Wi-Fi calling with an internet connection from the Apple Watch or nearby iPhone.
Because this is the GPS model, having your iPhone nearby matters for safety communication. If safety independence is a top priority, the GPS + Cellular version may be better.
Water Resistance
Apple Watch SE 2nd Gen is listed as water resistant to 50 meters and swimproof. Apple says it may be used for shallow-water activities such as swimming in a pool or ocean, but it should not be used for scuba diving, waterskiing, high-velocity water activities, or submersion below shallow depth. Apple also notes that water resistance is not permanent and can diminish over time.
This makes the watch suitable for everyday water exposure and swim workouts, but users should still care for it properly. Avoid exposing it to soaps, lotions, perfumes, harsh chemicals, and high-pressure water when possible.
After swimming or sweating, it is a good idea to clean and dry the watch and band.
Battery Life and Charging
Apple lists the Apple Watch SE 2nd Gen with all-day battery life up to 18 hours of normal use. Apple also states that it can charge up to 80% in about 1.5 hours using the included Apple Watch Magnetic Charger to USB-C Cable.
For most users, this means daily charging is likely. If you use sleep tracking, you may need to charge the watch during the morning, evening, or while getting ready.
Battery life can vary depending on notifications, workouts, brightness, GPS use, apps, and settings. If you use GPS workouts often, expect battery usage to increase.
Performance and Storage
Apple Watch SE 2nd Gen uses the S8 SiP with 64-bit dual-core processor, includes a 2-core Neural Engine, and has 32GB capacity, according to Apple’s technical specifications.
For daily use, the watch should feel smooth for notifications, workouts, alarms, timers, Apple Pay, music controls, weather checks, and health apps. It is not Apple’s most advanced watch chip today, but it remains capable for the core smartwatch tasks many users need.
Smart Features
The Apple Watch SE 2nd Gen supports many useful smartwatch features, including notifications, calls through a connected iPhone, Apple Pay, Siri, alarms, timers, reminders, messages, activity sharing, music controls, maps support, and apps through watchOS.
Apple lists connectivity features such as Wi-Fi 4, Bluetooth 5.3, Apple Pay, and GymKit.
For everyday users, these features make the watch useful beyond fitness. You can check messages quickly, use Apple Pay at supported locations, receive calendar alerts, set timers while cooking, track workouts, and monitor daily activity.
Midnight Sport Band S/M
The Midnight Sport Band S/M is a practical choice for this watch. It is simple, flexible, and easy to match with the Midnight case. The S/M size is usually intended for smaller to medium wrists, but buyers should still check wrist fit before ordering.
Apple lists the 40mm Apple Watch SE as fitting 130–200mm wrists.
If your wrist is outside that range or you prefer a looser fit, check band sizing carefully before buying.
