If you look at the G-5600J screen at an angle, you can see the text "BRT" right above the tens-of-seconds digit in the same location as "SNZ", "ALM", and "SIG". What is "BRT"?
Also, after replacing the CTL1616 battery, I put the watch outside in direct sunlight for about 2 to 3 hours. When I checked on it, the screen was blacked out, as if the LCD was all smeared about 80 percent of the central part of the screen in a disk-pattern. The watch was warm-to-hot. I took the watch inside, and as it cooled down the black wash-out problem went away and the screen looks normal. But, I was really worried. The manual cautions that the watch could get hot in direct sunlight. It even offers the time of 5 hours to take the charge from zero to full in direct sunlight. But, this LCD black-out is not mentioned. Is it not a problem? Is my watch defective?
