i need manual settings for a Justin sport watch all details I have is that it has 4 setting buttons, work with solar power and slide the day, date and time over the screen. On the back is a sticker that says digital black series and that is all the info I have on the watch. I bought the watch at a shop and the owner promised to give me the settings manual, but never are available to help me. If you could help me I will really appreciate it.
