To commemorate the 125th anniversary of the legendary 19-ligne caliber movement which essentially established the Omega brand as one of the thriving forces which has endured and carved out an astonishing legacy for over a century. Lets take a stroll down memory lane towards the new “Omega De Ville Trésor 125th Anniversary Edition”.

The introduction of the 19-ligne calibre represented a significant change for the horology industry with its innovative. It was the first time watchmakers had established an “industrial scale” production line, crafting each component to very precise specification making them interchangeable, which allowed for a much more streamlined assembly.

Such a concept of efficient workflow brings to mind Henry Ford’s assembly line for the mass production of an entire automobile back in 1913, but Omega’s factory pre-dates Ford by two decades. This system was patented by the company on 1 August 1894 and became such a success, it was soon adopted by the entire Swiss watch industry.


“Ligne” is an ancient unit of length that was first introduced in France and was widely used in the Swiss Watchmaking industry and corresponds to 2.26mm. And besides the aforementioned industry-changing workflow, in simpler terms with the 19-ligne calibre Omega perfected a method for winding your pocket watch and setting the time by only using the crown.


The 40mm case is made of 18k yellow gold with a solid case back, which features a red enamel medallion engraved with a vintage font Omega logo, a reference to the “19 Cal.” and “125 YEARS” anniversary. Surrounding the medallion is an engraved patterned called damaskeening, which Omega originally used to decorate the 19-ligne movements over a century ago.


But, despite these callbacks and inscription, underneath the case back is actually an all new caliber 8929, not the 19-ligne. This explains why Omega opted for other embellishments, instead of an exhibition case back. All topped by a scratch-resistant sapphire crystal with anti-reflective treatment on both sides. Water-resistance on this watch is capable of reaching up to 30 meters (100 feet).


Time is exhibited on a rare red enamel dial with 18k yellow gold baton-style hour index markers, with double-baton markings for every 15-minute increment, while the inner flange is discreetly dotted with minute index markings. There is a “red carpet” appeal that seems to emanate from this watch and its sumptuous simplicity.


The central hour, minute and seconds are also made of 18k yellow gold. In essence that sums it up, besides the Omega logo on the upper-half and the inscription “CO-AXIAL MASTER CHRONOMETER” on the lower-half of the dial. But, despite the lack of feature the warmth that emanates off this dial is quite captivating and establishes a presence.
