The immediate problem becomes - assistive tools will show the clock has 12 options for minutes and seconds with gaps. Not sure if VBtn approach is correct here. Maybe the clock should have role spinbutton and accept up/down keys to change, while the visual representation is more of a guide for people relying on pointer-based interaction.
