locking stone

As the two escape wheels A and B rotate meshed together, one of them is locked when an impulse/locking tooth, standing upright from the escape wheel, rests on the wide straight locking stone of the detent.

The first and largest dome was completed in October 2006 when bone relics of Gautama Buddha were enshrined in the central locking stone of the dome on 29 October 2006, making it the world's largest structure containing relics of the Buddha.
