The Cosmos Vault PFB204 smartwatch promises a blend of style and functionality, boasting a bright AMOLED display, Bluetooth calling, and comprehensive health tracking capabilities. After several weeks of rigorous testing, I’m ready to share my in-depth review, detailing its strengths and weaknesses. This review will cover everything from daily wearability to its performance during intense workouts.

The PFB204 packs a lot into its sleek design. The 1.43-inch AMOLED display is vibrant and highly legible, even in direct sunlight. The 600 nits of brightness really make a difference. Navigation through the menus is intuitive, and the touch responsiveness is excellent. Beyond the display, the smartwatch offers a range of features, including Bluetooth calling (a feature I actually used quite a bit), heart rate monitoring, SpO2 tracking, sleep analysis, multiple sports modes, and a step pedometer. The ability to receive notifications for calls, texts, and social media apps is also a significant plus. The multiple watch faces are a nice touch for personalization. The metal alloy strap and case feel premium, adding to the overall feel of the product. The magnetic charging is a convenient feature, and the overall design is undeniably stylish.

In terms of performance, the Cosmos Vault PFB204 generally performed well. The heart rate and SpO2 readings seemed accurate when compared to other devices. The sleep tracking is basic but provides a reasonable overview of your sleep patterns. The various sports modes accurately tracked my steps, distance, and calories burned during runs and walks. However, the GPS is not built-in, so you’ll rely on your phone’s GPS for precise location tracking during outdoor activities. Battery life is another key aspect, and while the advertised 5 days (AOD off) is achievable with moderate use, I found the battery life to drop significantly when using Bluetooth calling frequently (as expected). With Bluetooth calling and Always-On Display (AOD) enabled, I generally got about 2 days of battery life, which is fairly standard for smartwatches with these features.

Pros:

• Bright and vibrant AMOLED display
• Bluetooth calling functionality
• Accurate heart rate and SpO2 monitoring
• Multiple sports modes and activity tracking
• Sleek and stylish design
• Convenient magnetic charging

Cons:

• Battery life could be better with heavy usage
• No built-in GPS
• Sleep tracking is basic

Overall, the Cosmos Vault PFB204 is a solid smartwatch offering a compelling combination of features, style, and functionality. The bright display, Bluetooth calling, and comprehensive health tracking capabilities make it a versatile option for everyday use. While the battery life could be improved, and the lack of built-in GPS is a drawback for serious athletes, the overall performance and value make this smartwatch a worthy contender in its price range. I would comfortably recommend the Cosmos Vault PFB204 to anyone looking for a stylish and functional smartwatch that doesn’t break the bank. For most users, the trade off is worth it for the sleek design and calling function.
