I just started wearing a couple of ani-digi watches a couple months ago. This might seem like a silly question, but I'm heartened that there some silly people here who will take it in the right spirit.
On Casio anologue/digital watches the minutes hand advances in 20 second increments. There is a choice of either having the minute hand "fast", i.e. it advances to the full minutes when the digital seconds reach :40.
The other option is to have it advance to the next full minute at :00 seconds.
I go for the first option since even though the difference is only a third of a minute, I'd rather have it appear slightly ahead than behind.
What is your practice?
