Ligne, an old-fashioned unit of length first introduced in France, was widely used in Swiss watchmaking. Watch movements used to be named according to their diameter and one inch comprises 12 lignes. One ligne is about 2.26mm.
Omega had stopped producing the original 19-ligne calibre in 1923, but the last components in stock were put away in the Omega Museum, guardian of the brand’s history and heritage timepieces, for close to 100 years. These parts have been retrieved from its vaults and watchmakers at its Atelier Tourbillon are busy using original bridges, mainplates, escapements and bimetallic balance springs to recreate 19 new movements and imbue them with “a truly authentic and historic spirit”.
As a brand synonymous with evolution, Omega is fitting the second-generation 19-ligne with an innovative Swiss hand-setting system. Other updates include new parts, such as the barrel, main spring and some screws. The chatons and ruby stones will be recreated and the entire gear train will be recalculated to meet modern standards.
For an artistic flourish, the revitalised movement will be decorated with an intricate “damaskeening” pattern used by Omega early in the last century. When everything is in place, it will be assembled with a crown at three o’clock and placed inside a half hunter pocket watch.
“People like pocket watches, especially one built from original movements,” says Aeschlimann, after welcoming guests to the 125th anniversary celebration. “They appeal to young people and collectors.”
Limiting production to 19 units in keeping with the name of the movement is novel, but would that number be enough to satisfy collectors?
“It is never enough. We want to make it exclusive,” he adds, because owning a watch with a calibre given a new lease of life is “an emotional thing”.
