Patek Philippe Minute Repeaters - Musical Instruments of Time

‘Minute repeaters are the musical instruments of time,’ says Alexandre Bigler, vice president and head of Watches at Christie’s Asia Pacific. ‘Relative to the complexity of minute repeaters, tourbillons are just standard. Minute repeaters are fascinating, because the sound they produce engages the emotions. Like with music. People of all ages have a childlike fascination with them. There’s a real allure to a minute repeater.’

Bigler is as charmed by them as the next person. Small wonder: minute repeaters — which use a tiny hammer and gong, typically to chime the hour, quarter hours and minutes — are notoriously hard to make. A Patek Philippe for example takes hundreds of hours to assemble. The issue is not simply one of mechanics or microscopic tolerances, but also the need to master sonics and the forces that produce them.

‘Patek Philippe may not have pioneered the minute repeater, but it was arguably the first to master the building of it on a commercial scale, and with a great sound,’ explains Bigler. The first minute repeater was produced in Germany by an unknown clockmaker in 1720, and in the late 1700s, Breguet introduced the idea of a two-tone chime. In 1839, Patek Philippe sold its first chiming repeater pocket watch.

But the nature of a chiming complication brings with it highly qualitative, yet often universally unanimous judgment on its aural aesthetics – a beautiful chime is a function of the quality of attack, harmony, pitch, volume, resonance, rhythm, and frequency. To create a repeater that works reliably and that sounds fabulous, is an ability limited to precious few watchmakers. As is true with any creative or technical endeavor, a tiny minority of watchmakers produce a disproportionate quantity of minute repeaters worth their chime. Laurent Junod, long-time technical director at Patek Philippe, suggests that the number of watchmakers competent enough to make a repeater to be no more than fifty in Switzerland, of which fifteen of them work for Patek.

The process for hand producing a Patek Philippe minute repeater is done by a single watchmaker who works on the repeater from beginning to end - typically 200 to 300 hours of assembly, excluding further optimization. This watchmaker approves it then proceeds to an echo-free chamber, where the parameters of its chimes are recorded and computationally analyzed against a template of previously approved and archived repeaters. Thus ensuring continuity in the acoustic qualities across all Patek watchmakers and chiming watches.

The repeater is then presented to the head watchmaker overseeing the chiming complications, and then finally – and most famously – to Thierry Stern, President, for his approval; in the same way as it was presented to the ear of Stern’s father and grandfather before him. The great majority of repeaters are approved by this stage, but not to the extent where this presentation is a mere formality. Thierry Stern has the final say in whether a watch is ready for their client.

Born of purpose, repeaters originated before widespread artificial illumination, to allow time to be determined in the dark. They were also used by the visually impaired. Today, repeaters are chosen for fascination & appreciation. The beauty of the minute-repeater is that there is no other watch complication, whose design, assembly, and tuning of the musical chimes demands as much of a watchmaker’s prowess. The acquisition of a minute repeater is to own a unique, precise mechanical piece of art and a finely tuned musical instrument. These watches fully encompass Patek Phillippe’s philosophy of artistically engineered watchmaking.
