I actually like a 24 hour analogue clockface

You must be very rarely satisfied then! I vaguely remember seeing a 24h analogue clockface once, but I can't remember where (Crewe Station?).

The Fitzwilliam Museum in Cambridge has a longcase clock showing French Revolutionary time: 10 hours in the day, 100 minutes in the hour. (As Eric Hobsbawm put it, the only lasting effect of the French Revolution was metrication.)
