The only thing I can think of for myself is an insistence on setting my alarm and time in odd sum-related times.
For example, if I need to get up @ 7 am, I will choose either (a) 6:51, or (b) 7:07. I also set the time in the same manner.
I only do this on my alarm clock, however. My watch, cellphone and any other clocks I don't care, although I do sometimes set my microwave cooktimes by the same method.
I am not sure where you draw the line between a compulsion and a superstition. I have always had bad luck with waking up with alarms, so over the years I have had to invent elaborate mechanisms to ensure I get up on time. At some point, my time-setting seemed to work, so I am superstitious about ever changing it, even though it probably had little to do with anything.
