Whenever the time is set on a mechanical watch, one invariably pulls the crown. The intuitive action typically brings the seconds hand to an immediate halt. It is also known as, in a self-explanatory term, stop seconds. The temporary stoppage enables the time displayed on the watch to be synchronised correctly down the second against an accurate timekeeping source, which otherwise wouldn’t have been possible if the seconds hand were to keep chugging along.
The hacking seconds mechanism works by releasing a hacking lever that interrupts the balance wheel, stops the gear train and holds the seconds hand. After correcting the hours and minutes of the wristwatch, one anticipatory waits for the reference seconds to align, before clicking in the crown of the watch to resuscitate the mechanical movement, bringing the watch and the source in sync. This is the marvel of hacking seconds, a poetic but pivotal feature that may seem simple but often overlooked for increasingly complex mechanisms.
Although the hacking seconds has existed for some time – since the 18th century in fact – its ubiquity in wristwatches was a rather recent inclusion. While most modern mechanical movements are incorporated with such a feature, there are exceptions still – some tourbillon movements are built without, inter alia. A significant number of vintages don’t even offer it. The popularity and indeed the importance of hacking seconds amplified in the years of World War II when wristwatches played a greater role in military coordination. Soldiers relied upon the hacking seconds function to synchronise their watches. Precision was central to successful execution of tactical commands as they would have to move at the exact moment as planned. The mechanism gradually expanded its presence in wristwatches in the ensuing decades, beyond field and tool watches where its importance and practicality were proven, culminating in an omnipresence across marques and sizes today.
