Jaquet Droz’s Grand Seconde collection is seeing color. The latest timepiece to join the collection, the Grande Seconde Quantième Ivory Enamel, brings a welcomed visual and mechanical update to the line, which hasn’t seen any new watches join the collection in over twelve years.

Featuring a completely new movement that uses a silicon balance spring to regulate and control its timekeeping mechanism, the Quantième Ivory Enamel showcases a new era of time-telling precision that can be seen through the watch’s back crystal and underneath Côtes de Genève–finished bridges.

But it’s not just the mechanical evolution that has buyers and enthusiasts alike singing the Quantième Ivory Enamel’s praises. Though the watch has retained its iconic shape, its lower subdial has been recessed to create a sense of depth that the brand has not experimented with before. It also features a new dial design that’s marked by the distinctive figure eight, consciously created by the intersection of the two dials, which uses grand feu enamel method, which bakes the decorative elements, lines and indexes during the enameling process rather than painting them on later.

Available in either red or white gold in either 39 mm or 43 mm, the watch retails for $19,400 and $20,000, respectively, on the Jaquet Droz website.
