The Octo Répétition Minutes Retro with jumping hours and retrograde minutes from Bulgari Gérald Genta Collection belongs to the category of masterpieces of horological micromechanical engineering that express the passing of time in sound. On demand, meaning by sliding a dedicated bolt, the user can choose to have it strike the hours, quarters and minutes: each hour on a low-pitched note, each quarter-hour on two low/high-pitched notes and each minute on a high-pitched note. The cadence of the G and C notes sounded is optimised: the 31 notes required to sound 11:59 chime out in around 15 seconds, which is neither too slow nor too fast and creates a melodious and easily audible sound.
The striking mechanism activates two gongs set to a third musical interval to differentiate between the hours, quarterhours and minutes. The lower gong strikes the hours, the gong set to the upper fourth musical interval strikes the minutes, and both are used to strike the quarter-hours. Within the family of Grand Complication models, this watch is distinguished by a combination of a minute repeater mechanism with a jumping-hour display and retrograde minutes indication. This masterpiece embodies a stunning blend of exclusive contemporary design and noble watchmaking traditions.
