The Latest Omega Speedmaster Caliber 3313

The new automatic coaxial version (311. of the iconic Omega Speedmaster is purpose designed for those who like big tool watches. At 44.25mm, it's noticeably larger than the 3570 with a moderately wider tachymeter bezel.

This new model offers the advantage of a date display and automatic winding, but could lose the attention of a few purists with the evolution of the dial design. However, for any fourty-plus owner, the larger markings make the watch that little bit easier to read.

This large and latest Speedmaster is noticeably heavier than the moonwatch and features a new bracelet design using screws instead of the old pins and collars they used on earlier models. The specifications of the watch are as follows:

…Omega caliber 3313 Self-winding Chronograph
…Co-Axial Escapement
…Column wheel mechanism
…52 Hour Power reserve
…Date at the 6 o’clock position
…Continuous seconds hand at the 9 o’clock position
…Matte black dial with recessed sub dials for elapsed minutes and hours
…Scratch resistant sapphire crystal with anti-reflective treatment on the inside
…Scratch resistant sapphire crystal exhibit case back
…Water resistant to 100 meters (330 feet)

This new version maintains a strong design link with its predecessors while offering new features. It satisfies many of the demands of contemporary owners, and while some may feel that the exhibition case back is a travesty, it certainly is a joy to look through and see the movement go through its paces.

the Fredric Piguet co-designed and manufactured Calibre 33xx has had a mixed reception amongst some Omega aficionados, notably the late Chuck Maddox. But, while it may have its detractors it certainly has a cohort of followers on the major watch forums. Notwithstanding improvements to this movement in later iterations, I believe there are better chronograph movements around.
