We are pleased to offer this OMEGA Seamaster Diver 300M Master Chronometer Co-Axial 42mm accompanied by all of its cards, booklet, boxes.

It is collector new, purchased by a collector with a large collection who stored this watch in new condition along with a number of other watches and did not wear them before his passing away.

Mating beauty, class, craftsmanship and usefulness, the watch stands out as a quality time piece to even the casual of observer. With its polar white dial with wave pattern and mixed black and red printing, large luminous hands and highly raised hour markers, and a calendar window at 6 o'clock its face possesses both a high degree of utility and style.

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.
