Jason Snell on his six colors blog features the Utility watch face as one of his favourites. I think I will use this face a lot too. My preferences are to have the alarm in the top left corner, timer in the top right corner, analog time in the middle, and full date along the bottom. On second thought I might have the date in the middle too and my next calendar item on the bottom. Good thing these preferences can easily be changed.
Almost what I want but with temperature in Celsius or with other time information like an alarm or timer in the top corners.
