Okay, next case:

When you don't press the button, the pedometer is a perfectly usable
digital watch. (This is actually closer to the vivofit's reality, except
that said watch goes dark when kept at rest for a long enough time. In
which case, moving your wrist lights up LEDs... But let's stick to the
imaginary example.)

Is it still zilzul Shabbos when you have a perfectly Shabbosdik reason
to wear the watch in addition to tracking one's walking?

Tir'u baTov!
