We are pleased and proud to offer this OMEGA Seamaster Aqua Terra Co-Axial Chronometer 41.5mm watch accompanied by all of its cards, booklet and boxes.

It was purchased by a collector with a large collection who only wore it a relatively few number of times before his passing away. It has one mark on the left side. Otherwise it presents like new.

Mating beauty, class, craftsmanship and usefulness, the classic yet robust watch stands out as a quality time piece to even the casual of observer. With its strong black dial with maritime Teak Concept pattern, day of the week window at 12 and calendar window at 6 o'clock, large luminous hands and raised hour markers, its face possesses both a high degree of utility and style.

Like a Rolex President, it is double quick-set: both the day and the date can be quick-set through the crown.

Although the mechanical watchmaking industry has a history of progressing slowly over time, one invention carried it a giant leap, the co-axial Escapement. Considered by many to be one of the most significant watch technology advancements in the last 250 years, the co-axial escapement functions with little need for lubrication.

Until 1999 when Omega released their co-axial line, these escapements could only be found on specialty watches selling for $150,000 and up.

We have tested the watch, and it continues to keep "as new" time.

Included with the purchase is a full one-year international warranty on the movement and its function.

The watch's page on the Omega website can be found here.

Don't miss the opportunity to own a watch that is functionally like-new worn only a few times and cosmetically mint, except for one mark, for a fraction of the price of a new one.
