Detailed Feature Comparisons
Design and Construction
Both models share the same durable jet black aluminium casing with a sporty, minimalist look. However, the 46mm variant has a noticeably larger footprint, making it more suitable for those who prefer a bigger screen or have larger wrists. The 42mm version is more compact, lighter, and may be more comfortable for smaller wrists or users who prefer a less prominent watch face.
Display Quality
Both watches feature the Always-On Retina Display with high brightness and sharp resolution. But the 46mm version provides a slightly larger viewing area. This can be helpful for reading messages, tracking workout stats, or using on-screen apps with less eye strain. The 42mm still performs well, but the screen feels more limited when multitasking or viewing detailed data.
Performance and Processor
Both models are powered by Apple’s new S10 chip, offering smooth performance, faster app launches, and efficient power usage. There’s no difference in processor or RAM between the two, so users can expect equally fast and responsive usage from either version in terms of speed and efficiency.
Connectivity
This is where the biggest difference lies. The 46mm model supports GPS + Cellular, allowing you to make calls, stream music, and receive notifications even when your iPhone is not nearby. This is perfect for runners, cyclists, or travelers who want more freedom. The 42mm model is GPS-only, meaning it requires a nearby iPhone for full functionality.
Battery Life
Thanks to its slightly larger size, the 46mm model can house a slightly larger battery. While both watches deliver all-day battery life, the 46mm version may last a bit longer during mixed usage or cellular activity. The difference isn’t huge, but it’s noticeable on long days or during travel.
Fitness and Health Tracking
Both watches offer the same advanced fitness and health features. These include ECG, blood oxygen monitoring, heart rate tracking, and sleep analysis. You’ll also get cycling and running metrics, Fall Detection, and Apple’s Fitness+ support. No major difference here—both are equally equipped for health tracking.
Software and Compatibility
Running on watchOS 11, both models support the latest Apple Watch apps and services. You’ll get access to widgets, customizable watch faces, and seamless integration with iOS. Updates and features will be identical, regardless of case size or connectivity.
FAQ

Can I use the GPS-only version without an iPhone?
