This watch has served me well but I barely use is these days that's why I decided to sell it. Everything is working perfectly and it still connects to newer phones. It's very durable.
The wrist band is not original apple but you can just get a new pair as wristbands are not that expensive.
If anyone was wondering: Height: 42.5mm Width: 36.4mm Depth: 10.5mm Case Weight: 30g
