The present watch is fitted with a so-called "Cathedral" repeating which thanks to its rich and full-bodied sound resembles the chime of the bells of a cathedral.
The repeating mechanism of this watch consists of a high-tone and a low-tone gong. When the repeating is activated, first the number of hours are stroke by means of one of the two hammers on the low-tone gong, followed by the quarter hours with double strikes on both the low-tone and the high-tone gong, and finally the number of minutes which have elapsed since the last quarter-hour with one hammer on the high-tone gong.
The length of the gong in a standard repeating mechanism corresponds to almost precisely one turn in the movement whereas those of the "Cathedral" mechanism exceed the case circumference by at least one and a half, even two turns. Consequently, a much richer and fuller timbre is achieved.
This mechanism is now used in highly complicated wristwatches such as Patek Philippe's Sky Moon Tourbillon.
