The only watch that you don't need the manual to set! The time and alarm can be adjusted in a few seconds! There are inexperienced users (I already read two reviews) who say that to set the time or alarm you have to click minute by minute, which practically makes it difficult to use. Obviously, they don't know that if they hold down the button (+ or -), the minutes start to run quickly and it can be adjusted in no time! It's important that both the screen lighting and the snooze (5-minute delay) can be activated with a simple touch on any part of the top surface of the watch. I am thrilled with the purchase! There is no manual in Greek, but you really don't need it. Just know that the back selector has three positions: Clock - Off - Alarm. After setting the time and alarm, put the selector in the middle (Off) to stop the digits from flashing on the screen. Initially, I had given it 5 stars. However, since the morning of the next day when I set the alarm to go off, it did go off, but did anyone hear it? A minute later, it supposedly rings louder! If you stick it with tape on your ear, you might hear it. Otherwise, it's impossible! Huge disappointment and I even threw away the box!
