In-Depth: Quantifying Performance and Trade-Offs in Movement Design
There are a lot of traditions in the luxury watch industry. From the use of pegwood to polish bevels, to the Roman “IV” rendered as “IIII”, the culture of watchmaking is full of interesting customs passed down over generations. But the most fundamental tradition remains the reliance on incremental improvements towards better timekeeping. “Better” might mean absolute performance measured over a defined period such as an observatory trial (the objective of the superstar régleurs), or reliable long-term performance on the wrist. Regardless, for almost four hundred years the quest for better precision was the guiding principle of the trade. To paraphrase from historian David S. Landes’ Revolution in Time, “… it has always been the rule that the quality of [a watch] is a function of [its] precision.” Omega cal. 47.7 observatory chronometer, where the barrel and balance occupy almost all of the diameter. Image – Omega Today, some 50 years after mechanical timekeepers were left in the dust by their “better” electronic brethren, some makers of mechanical watches are more pious in their observance of this traditional approach to incremental improvement than their competitors. And if we look carefully, we can quantify this difference in approach by looking at how different watchmakers choose to use the available energy within their movements. Our interest was to find a way to quantify which watchmakers are making high-performance timekeeping choices and ...
