The minute repeater, a fascinating and intriguing creation, holds a significant place in the history of watchmaking. Among the luminaries of this intricate art, Abraham-Louis Breguet emerges as a visionary technician whose passion and ingenuity forever transformed this remarkable timekeeping mechanism. In the year 1783, Breguet introduced a groundbreaking concept that would shape the future of minute repeaters. Until then, these horological marvels chimed using bell-type gongs. However, Breguet’s innovative spirit led him to design the first repeating watches that struck a spring blade, departing from tradition. This departure not only marked a pivotal moment in watchmaking but also set the stage for Breguet’s enduring legacy. This year, the Maison Breguet pays homage to this legacy through a new Classique 7637 Répétition Minutes timepiece that embodies the brand’s commitment to innovation and tradition.
Minute repeaters are a pinnacle of horological complications, often described as miniature mechanical masterpieces. Beyond the intricate movement, they feature a complex chiming mechanism composed primarily of hammers striking a gong-spring. This intricate dance of components requires not only meticulous craftsmanship but also the careful selection of materials with exceptional acoustic properties. All of this artistry must be contained within a modestly sized case, adding another layer of challenge to the process.
Crafting a minute repeater demands an unwavering commitment to precision and skill. Astonishingly, over a month of intensive labor is invested in creating just one of these extraordinary timepieces. Breguet, with nearly 250 years of heritage, upholds this tradition at its Manufacture in the Vallée de Joux, a testament to the brand’s dedication to preserving the artistry of the past while embracing the innovations of the present.
The creation of a minute repeater transcends watchmaking and delves into the realm of acoustics. Collaborating closely with watchmakers specializing in high complications, acousticians play a crucial role in refining the auditory experience of the timepiece. Once the movement takes form, the meticulous process of tuning the gong unfolds in two phases: harmonic and melodic.
Within a specially designed anechoic chamber, the acoustician meticulously identifies the resonant frequency of each gong, a vital step in achieving the desired sound profile. Further refinement ensues as the pursuit of Breguet’s signature sound unfolds. Each minute repeater, hand-crafted to perfection, possesses subtle acoustic nuances that distinguish it from its peers, rendering every piece truly unique.
The artistry of a minute repeater extends beyond mechanics and acoustics, venturing into the domain of aesthetics. The minimalist dial of the Classique 7637 Répétition Minutes exemplifies a meticulous craft known as the grand feu enamelling technique. This delicate process involves applying colored powders, a fusion of silica and ground oxides, onto the dial through various methods. The true magic, however, lies in the firing process.
Layer by layer, each application of color undergoes firing at temperatures exceeding 800 degrees Celsius, resulting in a fusion that brings the dial to life. This intricate dance of heat and pigment can span several weeks, culminating in a singular dial of captivating depth and hue. Breguet’s iconic Arabic numerals, minutes track, and logo grace this canvas in a powdered silver hue, while open-tipped gold Breguet hands elegantly mark the hours and minutes. Activating the minute repeater is an experience orchestrated through a dedicated slide at 9 o’clock.
The Breguet Classique Répétition Minutes embraces a 42mm rose gold case, encasing the Calibre 567.2 movement. With a balance oscillating at 2.5 Hz, the entirely hand-chased mechanical hand-wound movement serves as an ode to the enduring art of craftsmanship. Upon turning the timepiece, the sapphire crystal caseback unveils the intricate dance of hammers crafted from polished steel. The placement of gongs, gong-holders, and hammers within the movement is a masterstroke of ingenuity. The gongs, rather than being attached to the plate, find their home on the case middle, enhancing sound transmission and quality.
The use of gold for crafting the gongs ensures a rich and harmonious tonality, while the shared acoustic impedance with the gold case amplifies sound transmission, a patent-worthy innovation exclusively from Breguet.
The Classique 7637 Répétition Minutes dons a black alligator leather strap secured by a gold triple-blade folding clasp, a luxurious touch that complements its exquisite craftsmanship. As part of the same collection, this horological masterpiece is also available in white gold, boasting a grand feu enamel dial and a midnight blue alligator leather strap.
