I have the ABL-100WE-1A version, it has LED backlight. all of the ABL-100WE have it. I press 3 seconds on the mode button, the watch syncs to the phone, syncs the clock and doesn't drift for a long time, and it also syncs the steps from pedometer.

These watches have cheap batteries that you can swap in two minutes. Not a big deal. Solar batteries cost a lot more money and will render this watch as e-waste in the future.
