The version that I have is the Amaztim M3 Ultra Military Smart Watch. There's a similar model called the Kospet Tank M3 Ultra. Both have GPS built-in and AMOLED screens (I only get watches with those kind of screens now, I will never go back to a regular "HD" screen). This is a big, bright watch, and since I have large hands, It's perfect for me. Here's a video of the Kospet Model (mine looks exactly the same):
