DClock is a nice suite that offers a clock, timer and stopwatch. All of the apps are free, and you can donate to the developer if you want.
Some of this app's other features are a stopwatch, which shares the same design as the clock and has hotkey support to start and stop it, a timer, and a to-do list manager.
All of the features are very simple, easy to set-up and use. And that is perhaps the best thing this app has to offer: simplicity and ease-of-use.
All of the components of DClock seem to be set to stay on top of your applications. And they are all portable; meaning that they don't require installation.
