The only reason I gave it four stars instead of five was for the design. If you look closely you will see that there are times when the minute and hour hands will obscure the digital numbers behind it. The vast majority of the time, this is not a problem. It did become a pain when I was taking myself through a spinning (bicycle) routine, which means I was changing the routine every minute or so. When the minute hand was around 35 and 40, it was really difficult to see the stopwatch numbers.
