Or, more likely, their alternatives. The Galaxy has some nice ones. The gist is that we think that obscuring the number is dumb, and you need alternative methods (up/down arrows, direct entry... click and get numpad even if softkb only) and scrolling as machine-era interface should be left as secondary; also, if you must scroll, click detents; ALSO: here and select list above, make sure the list is the right choice (can it be a series of buttons instead, to reduce number of clicks?), and pick good values. E.g. scroller for minutes on a calendar should usually be at 15 min intervals, and direct entry required for any odd numbers. This is not with select lists, because it's evolved to a special case only on mobile. So: a mobile pattern!

See the excellent thumbwheel on this page: http://www.space1.com/Artifacts/Space_Shuttle_Artifacts/Controls___Displays/controls___displays.html

Note how it works. VERY discrete clicks, vs. the vague rolling of many of them. Use the concept of an ideal machine-era thumbwheel, for all gestures. Even to suggesting haptic feedback for individual clicks.

As far as pushbutton to go up and down, those also existed in machine era! http://www.digitran-switches.com/specsheets/pushbutton.pdf Reference the difference between bidirectional and uni-directional. Use unidirectional if you are only going to increase, generally (e.g. snooze in incremental minutes, starts at minimum size). Either reduce the size of the other direction, allow direct input, or just assume circular input will work fine.

And even this: (the space shuttle one is not dissimilar) http://www.digitran-switches.com/specsheets/leverswitch.pdf Just as an example of how in the machine era multiple interfaces existed to meet specialized needs. Feel free to explore interactive design alternatives, as long as you meet the principles in this pattern and good design in general...
