How The World's Most Accurate Watches Are Made
Nearly every advance in watchmaking technology has been in the service of increased utility and functionality - even inventions that we now consider entirely luxurious affectations. The minute repeater, for example, was invented so a watch wearer could audibly check the time in the dark in the days before luminous treatment on dials. Even the tourbillon began its existence as a device for enhancing timekeeping accuracy, countering the effects of gravity on a pocketwatch’s movement. Thus it should come as no surprise that as the world entered the electronic era in the mid-20th century, watchmakers would attempt to harness the new technologies to improve the precision - and hence the desirability - of their products. Read on as we trace the evolution of timekeeping technology all the way up through today’s most accurate watches. Birth of the Chronometer Not long after the tracking of time migrated from giant clocks in the town square to portable devices carried in waistcoat pockets, and eventually worn on wrists (click here for a brief history of watches), the need for a standard of dependable accuracy in these mechanical timekeepers became evident. Hence the establishment of standards for which a timepiece could be deemed a "chronometer." The classical definition of a chronometer goes all the way back to the golden age of seafaring exploration in the 18th Century, when ships required the use of a highly accurate onboard clock that enabled their navigators to det...
