The patented repeating mechanism comprises some 250 individual parts working together as if in a mechanical orchestra. The design’s central elements are two steel gongs, which are struck by the two hammers when the repeating slide is pushed down. The minute repeater chimes out each full hour that has elapsed since noon or midnight with a single strike on the deeper-pitched gong (the tone is B flat), every quarter since the last full hour with a double strike – one on each gong – and every minute that has passed since the last quarter with one strike on the higher-pitched of the gongs. An all-or-nothing piece ensures that the chimes are only struck if the repeating slide is pushed down fully. The watch is equipped with the 98950-calibre hunter pocket watch movement, which goes back to the 1930s and which has since then been further developed, improved and modernized. The see-through sapphire-glass back provides an open view of the stylistic elements of the early F. A. Jones calibres, such as the elongated index, which facilitates the fine adjustment of the effective length of the balance spring. The nickel-silver plate and threequarter bridge are decorated with circular graining and Geneva stripes, respectively.
