The new automatic coaxial version (311.30.44.50.01.002) 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.
