Using magnets would definitely make for a cooler look, but this effect can be done using nails of varying heights.

  The thing that I wonder about (with nails) would be "what would happen if the the flexihand was able to wiggle past the peg when it moved from one peg to the next?" In that case, I believe, it would just be a regular clock style hand. It's possible that I've got the wrong mental model for how that would work.

    I think you'd put the nails at N+1 position, not N. (e.g. for the minute mark, you't put the nail at 6, 11, 16, etc. not 5, 10, 15). Then, the hand would press against the nail and progressively bend until it slipped past the nail entirely and jumped to the next 5 spot (and not yet be touching the next nail).
