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, these escapements could not be found on watches selling for less than US$150,000. That all changed when Omega released to the world a new line of co-axial watches. At the forefront of these watches stand the Speedmaster Broad Arrow watches, a truly inspired marriage of form and function.

From the easily read dial and broad arrow hands to the curved brushed case-edges, this is one handsome timepiece. It exudes quality and feels both luxurious and sports-worthy. Elegant, dynamic, and extremely capable it's sure to get a second look.

This Speedmaster '57 watch, ref. 321.93.42.50.13.001, was made in a limited edition of 1957 pieces. It remains in mint condition. It is a 9.8 out of 10. The watch itself is a 9.8 or 9.9 and the band shows a slight amount of wear and is about a 9.6.

Accompanying it are its original Omega boxes, chronometer and pictograph cards, and instruction booklet. Included with the purchase is a new one-year C.O.T. warranty on the movement and its function and a new timing certificate.
