In September 2025, Apple officially introduced the long-awaited Apple Watch SE 3. The device was unveiled on September 9, 2025, and is expected to hit the market on September 19, 2025. Positioned as a budget-friendly alternative to the premium Apple Watch Series and Ultra models, the SE 3 combines core smartwatch features with a lightweight, stylish design. For users looking for a balance between affordability, functionality, and modern Apple features, the Watch SE 3 is one of the most compelling wearables of the year.
Design and Build Quality
The new Apple Watch SE 3 inherits Apple’s minimalistic and modern design principles. Measuring 44 x 38 x 10.7 mm and weighing 26.4 g or 33 g, this model is incredibly lightweight—providing comfort even during extended wear.
Crafted with an aluminum frame, a glass front, and a plastic or sapphire crystal back, the SE 3 is both durable and visually appealing. The 50-meter water resistance rating makes it suitable not only for workouts but also for swimming and other water activities.
Available in Midnight and Starlight finishes, it blends seamlessly into a variety of styles, whether it’s casual wear, business attire, or fitness gear.
Display: Bright and Protected
The Apple Watch SE 3 boasts a 1.78-inch Retina LTPO OLED display, offering a crisp resolution of 448 x 368 pixels at 326 PPI. Apple has once again focused on brightness, with the screen reaching up to 1000 nits peak brightness—perfect for outdoor visibility.
Durability is enhanced by Apple’s new-generation Ion-X strengthened glass (2025 edition), delivering extra protection against scratches and everyday wear.
Performance: Apple S10 Chip and watchOS 12
At the core of the SE 3 lies the brand-new Apple S10 chipset, bringing a powerful dual-core CPU and PowerVR GPU combination. The device runs on watchOS 12, Apple’s most advanced smartwatch operating system to date, delivering smooth animations, faster app performance, and improved integration with the iOS ecosystem.
The SE 3 also comes with 64GB of storage—perfect for apps, playlists, and podcasts. Although it lacks expandable memory, the built-in storage is more than sufficient for most users.
Health and Fitness Features
Apple has built a reputation for health-focused wearable technology, and the SE 3 reinforces this legacy. Equipped with advanced tracking sensors, it’s a full wellness assistant on your wrist.

One of the highlights of the Apple Watch SE 3 is its future-proof connectivity. Supporting GSM / HSPA / LTE / 5G networks, the device ensures seamless communication whether you’re in a city or on the move. Equipped with eSIM support, the SE 3 offers independence from your iPhone when needed.

Battery and Charging Efficiency
Battery life has always been a crucial topic for smartwatches. While Apple has not disclosed the exact Li-Ion capacity, the SE 3 benefits from the energy-efficient Apple S10 processor and optimized watchOS 12.
Most importantly, it supports fast wireless charging—reaching 80% in just 45 minutes. This makes it ideal for those who need quick top-ups during a busy day.
