Insight: When Simplicity Belies Complexity, the F.P. Journe Chronomètre Optimum
The Chronomètre Optimum is arguably François-Paul Journe’s most complex no-complication creation. Being a time-only watch, the Chronomètre Optimum displays the same amount of information as the entry-level Chronomètre Souveraine, albeit for more than twice the price, with the Chronomètre Optimum retailing for US$129,500 in platinum and a bit less in gold. On a pleasantly asymmetric dial, the Chronomètre Optimum presents the wearer with the time, down to the second, and a power reserve indicator. Plain as the dial might seem, the Chronomètre Optimum’s appeal lies in its inner, and largely hidden, complexity. In fact, the cal. 1510 within ranks among the most sophisticated time-only movements on the market today. Chronometry Historically the tourbillon was never a complication, though it is often regarded as such today – though some prominent collectors disagree. In this context, it is difficult to label the features of the Chronomètre Optimum true complications. But since the timepiece was designed with chronometry in mind, its features of engineered accuracy might just qualify as a complication. Chronometry in mechanical watchmaking is regarded as a marriage between accuracy and precision, as there is a nuance between the two. Accuracy is the quality of a watch or clock to have a timekeeping deviation as close to zero as possible, whereas precision relates more to the consistency and stability of the timepiece’s rate, rather than to a temporary lack of devi...
