Introduction

For the past few weeks, I’ve been putting the Watch 4 smartwatch (model numbers TMA-L19 and TMA-B19) through its paces. This sleek device boasts a vibrant 1.75-inch AMOLED display and a surprisingly long battery life. But does it live up to the hype? Let’s dive into a comprehensive review to find out.

Features

The Watch 4 is packed with features. Beyond its stunning AMOLED display (390×450 resolution), you get an independent eSIM for making calls directly from your wrist. This was a surprisingly convenient feature, allowing me to leave my phone behind on several runs without missing important calls. The inclusion of GPS, NFC for payments, and a suite of health and fitness tracking options – including heart rate monitoring, blood oxygen level tracking, and sleep tracking – make it a comprehensive package. I particularly appreciated the accuracy of the sleep tracking, providing detailed breakdowns of my sleep stages.

The customizable watch faces offer a good degree of personalization, letting you tailor the watch’s appearance to your style. The notification system is robust, allowing for quick glances at messages and calls without having to pull out your phone. The 5ATM water resistance rating (50 meters) held up well during my showers and even a few swims in the pool.

Performance

The Watch 4’s performance was generally smooth and responsive. The AMOLED display is incredibly sharp and vibrant, even in direct sunlight. The battery life, advertised as up to 10 days, proved to be reasonably accurate with moderate usage. With heavy use (constant GPS tracking and frequent notifications), I found the battery lasted around 5-6 days, still very impressive for a smartwatch with so many features. The GPS accuracy was consistently reliable, matching my phone’s location data within a few meters.

The heart rate and blood oxygen sensors were fairly accurate, comparing favourably to my other fitness tracking devices. However, the accuracy can vary depending on the tightness of the band, so ensuring a snug fit is crucial for best results.

Pros & Cons

• Pros: Vibrant AMOLED display, long battery life, eSIM functionality, accurate GPS, comprehensive health and fitness tracking, comfortable design, water resistant.
• Cons: The user interface could be slightly more intuitive, and the notification management system could benefit from a more granular level of customization. Some users may find the band slightly stiff at first, but it softens up over time.

Final Verdict

Overall, the Watch 4 (TMA-L19, TMA-B19) is a fantastic smartwatch offering an excellent balance of features, performance, and battery life. The vibrant AMOLED display and the convenience of the built-in eSIM are standout features. While there’s room for minor improvements to the user interface, these are minor drawbacks compared to the overall positive experience. I highly recommend the Watch 4 to anyone looking for a feature-rich and stylish smartwatch.
