Seiko travel alarm
With but one exception, I consider the Seiko travel alarm (with "atomic" time and room temp) terrific for use both at home and on the road. It's reasonably compact for what it features and is nonetheless easy to read. The sole exception is that it has no volume control for the alarm; I do not need to hear it as loud as it is, but it can wake my wife as well as waking me. I muffled the "speaker" with cotton.
