This model may cost a little bit more than 158, but it is really worth it because of the lighting. When compared to the 158th, which just displays the minutes, this one clearly displays both the minutes and the seconds. When worn with a bracelet, the watch takes on an industrial, even retrofuturistic appearance. Time is kept well. I dropped it twice, which caused the speaker to break; now, it makes a very faint squeaking sound; you can't use the alarm clock and notification around every hour; nevertheless, this alarm clock wouldn't wake me up anyway, so the problem isn't that big of a deal. There is only a stopwatch and not a timer available. A straightforward and dependable little watch for hands of medium and average width.
