　　History of the Minute Repeater

　　Known alongside the perpetual calendar and the tourbillon as one of the three classic mechanical complications, the repeater, also known as a striking watch, has a history of several hundred years since its birth. Outstanding watchmakers have used their ingenuity to invent this mechanical device, which was highly practical at the time. It conveys time information through different rhythms of sound produced by hammers striking gongs; it can be said to transmit the sound of time to us.

　　Daniel Quare Pioneers Striking Clocks and Watches

　　Before Edison popularised the electric light in the 19 century, people lived in darkness. By this time, Western watchmaking had already undergone centuries of development, and various technologies were maturing. In the 17 century, during the 80s, the British watchmaker Edward Barlow invented the rack-and-snail striking mechanism. Ten years later, British watchmaker Daniel Quare further refined the striking mechanism; his technology focused primarily on the quarter-repeater—striking the hours and the quarters (15 minutes). Later, he further developed the half-quarter repeater (7.5 minutes), increasing the precision of timekeeping that could be conveyed through sound. Based on Daniel Quare's repeater technology, the quarter-repeater became the primary category of striking watches throughout the 18 century, and people gradually came to recognise and accept this magical, complex function that allowed them to tell the time in the dark. Although early repeater technology, represented by Daniel Quare, pioneered audible timekeeping, the limitations of craftsmanship and understanding meant these were not the bar-type gongs we use today; instead, they mostly used a method of striking metal bells. Furthermore, these works were primarily large mantel clocks, carriage clocks, and heavy leather-cased clocks. Nevertheless, Daniel Quare's contribution to the development of repeater technology is undeniable, and the safety-start mechanism he invented was the predecessor to the modern minute repeater activation system.

　　Master Breguet pioneered the history of the gong-spring striking repeater.

　　The truly groundbreaking 'gong-spring' striking mechanism, which has had a profound influence on modern repeater technology, was born in the late 18 century (around 1783). It was created by the renowned master watchmaker Abraham-Louis Breguet. Beyond ensuring a louder and crisper sound quality, the invention of the 'gong-spring' mechanism was most significant for making the miniaturisation of repeater watches possible. It is this structure that laid the foundation for the coiled gong-spring movement used throughout the industry today, allowing minute repeaters to become increasingly compact, while the tones produced by the gongs still retain the essence of Master Breguet's work.

　　By the 19 century, a more precise 'five-minute repeater' technology appeared in the watchmaking industry—the first strike represented the hour, and the second strike represented five minutes (or its multiples). Throughout almost the entire 19 century, as I am sure readers of Watch Home know, five minutes was the smallest time increment that most repeater watches could accurately indicate.
