OMEGA Seamaster Aqua Terra Annual Calendar New Watch

OMEGA Seamaster Aqua Terra Watch Collection has attracted a large, enthusiastic following since its launch. The line characterized by the distinctive "teak-concept" vertical lines on their dials has been extended with the release of the first models with an annual calendar complication.

The Aqua Terra collection is a perfect union of eye-catching design excellence and innovative 21st century watchmaking technology. The Annual Calendar models, in stainless steel or an elegant bi-colour blend of stainless steel and 18 Ct red gold, are a dramatic but logical next step in the mechanical watch revolution which has been taking place at OMEGA since the launch of the first Co-Axial calibre more than a decade ago.

The watches are powered by the OMEGA Co-Axial calibre 8601/8611, a high-precision COSC-certified chronometer which features the additional functionality of 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 March 1st.

The Aqua Terra Annual Calendar timepieces are also equipped with OMEGA's exclusive Si 14 silicon balance springs. Silicon is non-magnetic so the performance of the
Si 14 balance-spring is not disturbed by exposure to magnetic objects. While the performance of mechanical watches tends to deviate over time as a result of small everyday shocks, these disturbances have very little effect on Si 14 silicon balance springs.

The watches selected from the Aqua Terra Annual Calendar collection include a bi-coloured model in 18 Ct red gold and stainless steel and another in stainless steel. They feature OMEGA's patented screw and pin system bracelets which match the case metals.
