Audemars Piguet | Jules Audemars Grande Sonnerie, A limited edition pink gold quarter repeating, grande and petite sonnerie wristwatch, Circa 1995 | 愛彼 | Jules Audemars Grande Sonnerie 限量版粉紅金二問大小自鳴報時，約1995年製

The present Jules Audemars example houses the grande and petite sonnerie, one of the rarest and most coveted watch complications ever existed. Its marvelous mechanical calibre 2868 consists of more than 500 individual parts, all working in synchronized order to perform a tranquil audit sensation. As early as the 18th century, repeater timepieces has been around as a device to tell time in the dark. The grande sonnerie on the other hand, automatically chimes the hours and quarters at each quarter of the hour, while the petite sonnerie automatically chimes the quarter hour. A pusher at 11 o'clock activates the chime on demand, while a slider at 2 o'clock offers different settings to select the grande sonnerie, petite sonnerie or a silent function. With the advancement of technology, perhaps the repeater function has lost its practicality in terms of reading the time in the dark, however its mechanism and complexity are still very much appreciated by discerning collectors. The significance of the present watch cannot be overstated, as the Grande Sonnerie represents an important milestone in the history of watchmaking.
