BREGUET, HORLOGER DES HORLOGERS. Même ses pairs le disent.
Today few watchmakers are able to work in the tradition of their forefathers and founders. However, Breguet not only continues the tradition but is able to offer a rare and elusive pocket watch fit for a king: The Tourbillon Grande Sonnerie.
Genesis of ref. 1907
In creating the Tourbillon Grande Sonnerie, Breguet has sought to distill the vision of its founder into a modern-day pocket watch. Breguet’s watchmakers took inspiration from older pocket watches to create something fresh and unusual at the same time. To this end, the design team looked at the garde temps, a high-precision watch also known as a regulator. Breguet applied this description to his own watches fitted with lever escapements, according to the manufacturing and sales ledgers.1
The following example of a sleek pocket watch in white gold serves as a starting point for the birth of what would later become ref. 1907. A pared down dial with oversized chapter rings for both minutes and seconds make this an extremely practical timekeeper. The design is quite modern too, elements which were infused into the Tourbillon Grande Sonnerie. The most remarkable difference is of course the addition of the tourbillon, Breguet’s own invention, and a sonnerie. Serious complications indeed and an appropriate way of commemorating the heritage of Abraham-Louis Breguet.
Do we need pocket watches anymore?
The scythe of time has seen fashions come and go yet some things transcend cultural trends. That thing which is often called progress, ushered in by the machine age and now knocking on the doors of Artificial Intelligence, boldly declares the obsolescence of mechanical trinkets. From the paperless office to smart watches that make and receive calls and the eagerly awaited so-called Internet of Bodies. Life promises to be sheer bliss when everything around us is managed by Bluetooth and Wi-Fi!
Books, paper, pens and LPs were supposed to have been superseded by the digital age – even though LPs have seen a resurgence. Add to that wristwatches, pocket watches and clocks, all of which may seem antiquated in our fast-paced world and for those in busy and hectic environments. It is worth remembering that clocks have stood the test of time by their presence in and on schools, public buildings and churches. Tangible data carriers and mechanical timepieces therefore have their uses alongside evolving technologies from quartz to solid-state storage.
But it is precisely amid the noise and confusion of modern life that some appreciate the quiet stability and longevity that comes with physical artefacts. For they do not require ‘upgrades’ and are generally low-maintenance and give great pleasure, often to generations of owners.
A triumphant achievement
Ref. 1907 is a fitting tribute to the early pocket watches made by Abraham-Louis Breguet. A striking mechanism is combined with the tourbillon that was originally designed to compensate for the influence of gravity on the balance of a pocket watch worn or carried vertically. In this position the tourbillon acts as a regulator of the escapement as it rotates continuously on its axis completely through 360 degrees negating the effects of poising errors in the balance.
The dial layout is one of simplicity and legibility well suited to pocket watches. Here it can be seen in the form of a regulator dial displaying the hours, minutes, and seconds on three separate axes. Once upon a time, the regulator was a precision clock in the watchmaker’s workshop that gave the reference to which all clocks and watches in production were set or adjusted. To ensure maximum precision, the hands are positioned above the wheels inside the movement. The hour, minute and second hands are all on individual axes and not on the same axis as is usually the case.2
Each aspect of the silvered gold dial is wonderfully decorated by Breguet’s master guillochers, hand-engraved on a rose engine: clous de Paris adorns the main dial while the inner chapter ring for the hours is decorated with panier alterné. An off-centred chapter ring lends additional subtlety to the overall design.
To top it all off, ref. 1907 is endowed with the rarest and most luxurious set of complications – the Great-Strike. This is a complication so rare that to put it in perspective, few of the greatest names in watchmaking venture into this arena. The watch contains four separate options for the strike:
- Great-Strike or Grande Sonnerie, the watch rings on the hour every hour and every quarter hour, with low sounds for the number of hours and with a high-pitched and low double sound for every quarter;
- Small-Strike or Petite Sonnerie, the watch rings on the hour every full hour and the quarters at each quarter not corresponding to a full hour (no repetition of the hour at 15, 30 and 45 minutes past the hour);
- Silence, the watch does not ring any passage; nevertheless the minute-repeater function is still available;
- Minute-repeater or Répétition Minutes, pull the slide of the minute-repeater down as far as possible; the strike gives the time in the minute-repeater fashion: by a first low sound the hours, on two tones the quarters and finally the minutes with high-pitched sounds.
This ultra-complication allows the minute-repeater to override the strike if it is activated while the strike is functioning. As a result the watch must be wound in sequence to avoid damage and users should study the manual carefully before operation.
The movement is breathtaking in its mastery and a mechanical marvel. The observer is invited to linger over a ‘cityscape’ of fine and minute parts, beautifully polished and harmoniously assembled. A loupe will heighten one’s appreciation of the masterful execution from Breguet’s watchmakers: with anglage to perlage to Geneva stripes or côtes de Gèneve, the works exhibit specular highlights thanks to Breguet’s flawless finishing and poli noir screws. The plate of the movement bears the inimitable maker’s mark in the form of a hand-engraved oval plate showing the name and unique number of the manufacture. As expected, the watch has been adjusted for all six positions, reserved for Breguet’s rarest timepieces.
Pocket watch ref. 1907 is the result of painstaking work and collaboration among Breguet’s master watchmakers and is so much more than a mere journey through the archives. The Tourbillon Grande Sonnerie is a modern-day revival of the spirit of Abraham-Louis Breguet. The addition of a grande et petite sonnerie alongside Breguet’s revered tourbillon adds refinement of the highest quality to an otherwise simple regulator pocket watch. Such watches are rarely seen and present an opportunity for connoisseurs to own a Grande Complication that is exceptional enough to be exhibited in a museum.
