10 Best Smart Watches Under 100 2026 in the United States

The Apple Watch Series 11 (GPS, 42mm) is a highly capable smartwatch packed with advanced health and fitness features. It offers a bright, always-on Retina OLED display that’s sharp and easy to read, along with a durable, scratch-resistant glass and an elegant rose gold aluminum finish. Its fitness tracking is thorough, covering heart rate monitoring, ECG, blood oxygen, sleep score, and even hypertension notifications—ideal for those serious about health insights. It’s water-resistant up to 50 meters, making it suitable for swimming and other water activities, and the build quality is solid with IP6X dust resistance, ensuring durability for everyday use. The battery lasts about 24 hours with normal use, which means daily charging is needed, but it charges quickly if you’re short on time. Compatibility is limited to Apple iPhones, which is crucial to know if you use Android devices.

You can receive notifications, calls, and texts directly on the watch, and it supports Siri voice commands for easy control. Given the model’s advanced features and premium design, it is not realistically available under $100, which may be a significant drawback if budget is a priority. While it excels in health and fitness tracking, those looking for longer battery life or a simpler interface might find it less convenient. This smartwatch is best suited for iPhone users seeking a comprehensive health-focused device with a stylish look, but it is not an entry-level budget device.

The Apple Watch Series 11 (GPS, 46mm) stands out with a bright, always-on Retina OLED display that’s easy to read in different lighting conditions, which is great for everyday use. It offers a full day of battery life—up to 24 hours on a single charge—with fast charging that quickly tops up your watch for hours of use. For fitness and health, it’s packed with advanced features like ECG readings, heart rate monitoring, sleep tracking with a daily sleep score, blood oxygen monitoring, and even alerts for high blood pressure and sleep apnea. It’s well suited for people who want a comprehensive health tracker in a sleek, lightweight design that you can comfortably wear all day and night.

The watch is water resistant up to 50 meters and dust resistant, so it can handle swimming and outdoor activities without worry. Notifications, calls, texts, and music controls keep you connected seamlessly via your iPhone, making it a handy companion for daily life. On the downside, this model’s price is usually well above $100, so it’s not a budget option in that sense. Also, full functionality requires an iPhone, limiting compatibility if you use other smartphones. While the battery lasts a day, it may feel short if you use many features continuously.

The solid build and scratch-resistant glass add durability, but the aluminum case might not feel as premium as higher-end materials. To summarize, this watch excels in health and connectivity features and design but is more suited for those ready to invest more than $100 and who own an iPhone.

The Apple Watch Ultra 3 is a high-end smartwatch designed with durability and advanced health tracking in mind. It features a bright, always-on Retina display that's easy to read outdoors and during workouts, protected by a tough sapphire crystal and a strong titanium case. Its battery life is impressive, offering up to 42 hours on normal use and up to 72 hours in low power mode, which supports longer activities like marathons or multi-day adventures. Fitness tracking is very comprehensive, covering running, swimming, cycling, and many more sports, with precision GPS and detailed metrics such as heart rate zones and custom workouts. It also includes safety features like fall detection and emergency SOS, even allowing satellite communication when cell service is unavailable.

Compatibility is limited to iPhones starting from the iPhone Xs with iOS 18 or later, meaning it won't work with Android or older iPhones. Water resistance up to 100 meters and a dust-resistant design make it suitable for swimming, diving, and tough outdoor conditions. The watch supports a wide variety of notifications and apps, with cellular functionality allowing calls, music streaming, and messaging without a phone nearby.

The smartwatch is quite large and heavy compared to many others, which may not suit everyone’s wrist comfortably. Priced well above $100, it is not a budget option but rather aimed at users seeking top-tier features and rugged build quality. For those wanting a durable, feature-packed Apple device and willing to pay a premium, this watch performs excellently. However, simpler models better align with budgets strictly under $100.
