OMEGA De Ville Hour Vision Annual Calendar Limited Series

The De Ville Hour Vision Annual Calendar Limited Series is the refined result of 160 years of experience in the art of making mechanical watches. At the heart of the Hour Vision Annual Calendar is the exclusive OMEGA calibre 8611, a high-precision COSC-certified chronometer with an instantaneous jump annual calendar complication. This annual calendar automatically recognizes months with 30 and 31 days and needs to be manually corrected only once a year, on the first of March.

These extraordinary timepieces also have silicon balance springs which further contribute to their precision and stability.  The presence of the silicon balance springs is indicated by “Si 14” engraved on the caseback and balance arm.

The De Ville Hour Vision Annual Calendar, in a Limited Series of 160 pieces, is based on advanced Co-Axial technology exclusive to OMEGA: the Co-Axial Escapement and free sprung balance deliver stable accuracy and extended reliability over time. A 13-ligne movement with 18-Ct red gold rotor and balance bridge, the OMEGA 8611 has two series-mounted barrels with a 55-hour power reserve and a bi-directional self-winding mechanism. The intricate beauty of the mechanism is accentuated by the luxurious decorative finish, as fine black screws complement the delicate Geneva stripes presented with an arabesque pattern, a world premiere.

OMEGA’s rich heritage and unparalleled experience in the production of mechanical watches is expressed in every feature, beginning with the polished 18-Ct white gold case with four lateral openings in sapphire crystal allowing visibility of the meticulously-crafted movement.

The caseback of the De Ville Annual Calendar Limited Series bears the Limited Series number (0/160) along with the inscriptions Hour Vision and Annual Calendar. This exclusive timepiece is presented in a wooden box fitted with four lateral windows through which the watch is visible, echoing the four sapphire lateral openings in the watch case itself.

De Ville Hour Vision Annual Calendar Collection
The De Ville Hour Vision Annual Calendar Limited Series is complemented by a Collection of eight models, four in red gold and four in stainless steel, all with dials identical in design to that of the Limited Series.

The red gold models are available with silver or brown dials and a red gold bracelet or brown alligator leather strap.  Their meticulously-crafted movements are visible through four lateral openings made of sapphire crystal.   The steel models are offered with silver or grey dials and a steel bracelet or black alligator leather strap.

As with the De Ville Hour Vision Annual Calendar Limited Series, the timepieces in the Collection are driven by the exclusive OMEGA Co-Axial calibre 8611, which evolved from OMEGA’s revolutionary, state-of-the-industry calibre 8500. The calibre 8611 has an added instantaneous jump annual calendar complication which recognizes months with 30 and 31 days, meaning that it has to be manually corrected only once a year, on the first of March.  Its Co-Axial Escapement and free sprung balance deliver stable accuracy and reliability over time; the self-winding chronometers have a power reserve of 55 hours.

The De Ville Hour Vision Annual Calendar wristwatches are also equipped with another groundbreaking feature: they have silicon balance-springs for an unprecedented level of accuracy in a series production mechanical watch. Their presence is subtly announced by the “Si 14”, the chemical symbol and atomic number of silicon, engraved on a balance arm and the caseback.
