Why does a sidereal day last less than 24 hours?+
Earth turns relative to the stars in about 23 hours, 56 minutes and 4 seconds of solar time. It also moves along its orbit, so it must turn a little farther before the Sun returns to the same meridian. The sidereal dial still reads 24 sidereal hours per rotation.
What makes a regulator different?+
A regulator gives hours and minutes separate axes. Here, the central hand reads minutes, the upper dial reads 24 hours, and the lower opening reveals the tourbillon. The arrangement makes each indication easier to read on its own.
