While the typical quartz timepiece maintains a ☑ second a day average and good quartz timepieces make ☑5 seconds a month, by COSC standards, a quartz chronometer holds a requirement of ☒5.55 seconds a year. Some quick numbers to note: according to the Contrôle Officiel Suisse des Chronomètres (COSC), mechanical tickers are considered to be highly precise when they maintain a rate of −4/+6 seconds per day. As a result, high-precision quartz timekeeping is making a strong comeback. This redefinition is in no small part due to the presence of smartwatches, which are driving forward digital timekeeping efforts. In recent days, however, there’s been increasing interest in redefining electronically assisted timekeeping – quartz-powered timekeepers are no longer simply the more accessible option.
