Samsung Galaxy Watch8

At the Galaxy Unpacked 2025 event, Samsung introduced its latest wearables, the Galaxy Watch8 and Galaxy Watch8 Classic, alongside the Samsung Galaxy Z Fold 7 and Galaxy Z Flip 7.

The new smartwatch lineup brings meaningful upgrades in health tracking, design, performance, and software. In this article, we’ll focus specifically on the Samsung Galaxy Watch8 specifications and why it stands out in 2025.

Display and Design

The Samsung Galaxy Watch8 is designed to work best when paired with a Samsung smartphone, unlocking its full feature set. It comes in two sizes:

40mm model: 1.34-inch OLED display

44mm model: 1.47-inch OLED display

Both displays offer up to 3,000 nits of peak brightness, making outdoor visibility excellent.

Design-wise, the Watch8 is sleek, lightweight, and extremely comfortable to wear. Weighing just 30 g (40 mm) and 34 g (44 mm), it features a “cushion design”—a circular dial housed in a subtly square frame. This design not only improves comfort but also enhances health tracking accuracy. Compared to its predecessor, the Watch8 is now 11% slimmer.

For durability, it’s built with sapphire crystal glass on the front and an aluminum frame. It is MIL-STD-810H compliant and IP68 rated, making it dust-tight and water-resistant up to 50 meters (5 ATM).

Galaxy Watch8 Sensors

The Samsung Galaxy Watch8 comes with an upgraded BioActive sensor capable of monitoring a wide range of biometrics, including:

Heart rate

SpO₂ (blood oxygen)

ECG (electrocardiogram), to assess heart rhythm

Blood pressure monitoring, certified in many regions

Dual-band GPS for accurate outdoor activity tracking

Full sensor list: Accelerometer, gyroscope, heart rate sensor, barometer, altimeter, compass, SpO₂, skin temperature, BioActive sensor, and antioxidant index.

These advanced sensors offer more precise readings, especially when worn consistently, thanks to the improved fit of the cushion design.

Software Features

Running on Wear OS 6 with One UI 8 Watch, the Watch8 introduces new software enhancements tailored for health and fitness, including:

Bedtime Guidance

Vascular Load Tracking

Antioxidant Index

New Running Coach

These tools aim to give users deeper insights into sleep quality, stress, and overall health. The dual GPS also provides highly accurate route tracking during workouts and outdoor activities.

Performance and Connectivity

Under the hood, the Galaxy Watch8 is powered by the Exynos W1000 (3 nm) processor with 5 CPU cores, delivering smooth and responsive performance. It’s equipped with:

2 GB RAM

32 GB storage

For connectivity, the Watch8 supports eSIM with LTE, allowing users to make calls, send messages, and stream content directly from the watch without needing a phone nearby.

Battery Life

Battery capacity has been upgraded:

40 mm model: 325 mAh

44 mm model: 435 mAh

This is an improvement over the Watch7’s 300 mAh and 425 mAh batteries. The Watch8 supports fast wireless charging, offering quick top-ups and all-day usage. With efficient software and hardware synergy, the battery life remains reliable even with advanced features enabled.
