I sometimes use a digital wristwatch just to mix things up and I have a tough time sometimes translating how long to wait for pasta to cook - on an analog face, 11 minutes is easy to represent visually, but with a digital I have to do math in my head.
I have one digital watch, the Casio F-91W, along with a mechanical "jump hand" watch, which shows the time using a pair of rotating wheels which have digits written on them. Kinda cute, but also a little hard to read in low-light.
I admit I've used the rotating bezel of a diving-watch to time cooking more often than for timing dives. They're very practical for that!
You need a microwave oven like mine, with the apparently-by-design feature (mentioned as an aside in a Technology Connections video some years ago, as I recall) that one can program the seconds up to 99. 11 minutes is 10:60 . (-:
