The BW0504E smartwatch promises a compelling blend of features: a large AMOLED display, a substantial 600mAh battery, and comprehensive fitness tracking capabilities. After spending several weeks with this device, I’m ready to share my in-depth review, covering its strengths and weaknesses.

The BW0504E boasts a 1.96-inch AMOLED square display with a resolution of 240 x 286 pixels. The screen is bright and vibrant, even in direct sunlight, making it easily readable. Beyond the display, key features include Bluetooth connectivity for calls and notifications, a built-in music player allowing for local music storage, a heart rate monitor, sleep tracking, and multiple sports modes. The replaceable strap is a welcome addition, allowing for customization.

Battery life lived up to its 600mAh promise. With moderate use (notifications, basic fitness tracking, and occasional music playback), I consistently achieved 5-6 days on a single charge. Heavy usage, such as continuous GPS tracking, will naturally reduce this. The accuracy of the fitness tracking was generally good, though I noticed occasional inconsistencies in step counting compared to my other fitness tracker. The Bluetooth connectivity was reliable for calls and notifications, although I experienced the occasional drop-out, requiring re-pairing. The user interface is intuitive and easy to navigate. The built-in music player is a nice touch for those who prefer to leave their phone behind during workouts.

The build quality feels surprisingly solid for its price point. The zinc alloy case gives it a premium feel, although it can feel a bit heavy on the wrist for extended periods. The stainless steel band is comfortable, although the clasp isn’t the most secure, and I did experience occasional accidental loosening.

Pros:

• Excellent battery life
• Bright and vibrant AMOLED display
• Built-in music player
• Multiple sports modes
• Replaceable strap

Cons:

• Occasional Bluetooth connectivity issues
• Slight inconsistencies in fitness tracking accuracy
• Band clasp could be more secure
• Can feel a little heavy on the wrist

Overall, the BW0504E smartwatch offers impressive value for its price. The combination of a long-lasting battery, a beautiful display, and a range of features makes it a compelling option for those seeking a versatile fitness tracker. While it has a few minor drawbacks, these are largely outweighed by its strengths. I would recommend the BW0504E to anyone looking for a reliable and feature-rich smartwatch without breaking the bank.
