Black Smart Fitness Watch Metal Mesh Magnetic Band Emerge S3 Android & IPhone

Sleek black smart fitness watch with responsive touchscreen, metal mesh magnetic band and a charger. Tracks steps, calories, and heart rate with clear on-screen stats. Comfortable all-day wear and modern minimalist design. The original Emerge app is not longer available. They say there are several universal apps this watch can be connected to but I don’t have time for researching. I have charged the watch but have never used it.
