A chased vertical column supporting a globe with a silver equatorial hour-ring marked I to XII with stars at the half-hours; this globed framed in a fixed cast and chased vertical ring. The hour was formerly indicated by the tip of the Turk's spear or pointer, but is now shown by a curved iron pointer screwed to the vertical ring.

The star wheel for strike unlocking is fixed to this arbor. Striking train of brass, of the count-wheel type, with resting barrels, the count-wheel cut for a sequence 1 to 12.
