PolderCombination Clock, Timer and Stopwatch with Large, Easy-to-Read Digital Display, White

Q: how do you set the clock?

That one also took me a little while to figure out. Press and hold the Clock button until the screen clears. Press the Start/Stop button to select AM or PM. Punch in the time using the number buttons. You have to enter a 2-digit hour, so if it is 6 pm you need to enter 06. The key to setting the clock is that you need to enter digits for the seconds. As soon as I enter the seconds the clock starts counting down the seconds. If I put in the seconds I don't have to press the Clock button again. You know it is set when the clock starts counting the seconds.

Q: How is this different from the http://www.amazon.com/Polder-898-90-Clock-Timer-Stopwatch/dp/B00004S4U7/ref=pd_bxgy_k_text_y ?

They appear to be about the same. Possibly different color, might be slightly different. But they look the same and seem to provide the same functionality over all
