Ask HN: Is there something like a Casio watch module available as a desktop app?

I was looking for a compact desktop app with alarm, timer, and stopwatch. Then I realized my Casio watches are pretty much ideal for this, but 1) I'm not always wearing one when at the computer and 2) if I want to have 3-4 timers going at once, I could open more than one instance of the app.

Any tips appreciated. Desktop Linux, Wine OK.
