A Relook At Omega Speedmaster Auto (“Reduced”) September 30, 2011

Posted by Admin in Uncategorized.

30th Sept 2011

There are many reviews about the Omega Speedmaster Pro (diameter 42mm) and the Speedmaster “reduced” (39mm) available.

In essence, the main characteristic differences are,

(1)  The Speedmaster Pro is deployed with manual hand-winding thicker mechanical movement while the Speedmaster “reduced” comes with a more sophisticated automatic mechanical thinner movement.  The speedmaster “reduced” is more accurate with 28,800 beats per hour (4Hz).

(2)  The Speedmaster Pro remains an icon “Moon Watch” classic. It’s therefore a desired collectible.  The Speedmaster “Reduced” is a modernized & improved automatic chrono in comparison.

Review of the Omega Speedmaster Automatic

Movement: Technical Info
It is powered by an exclusive decorated, rugged and reliable movement – the Omega 3220 caliber – which is different from the previous versions of this model, since they used to have the 1140 movement that lacks the desirable luxury finish. It has rhodium-plated finish, beautifully decorated with perlage (circular graining) on the plates, and Côtes de Genève (Geneva stripes) on the winding rotor mass and bridges. This movement, exclusive to Omega, is a slim 45-jewel self-winding Chronograph with central hour hand, central minute hand, small seconds at 3 o’clock, 12-hour totalizer at 6 o’clock, 30-minute totalizer at 9 o’clock, and central chronograph hand. The movement is of modular construction, based on the ETA 2892-A2 with the exclusive Dubois-Dépraz 2020 module. Power reserve: 40hours. This movement’s dimensions are 30mm diameter by a height of 6.5mm. The high 28,800 beat-per-hour frequency (4Hz) make the small seconds hand at 3 o’clock as well as the central chronograph hand glide smoothly–noticeably smoother than on its big brother the Omega Speedmaster Professional which has a slower frequency of 21,600 beats-per-hour (3 Hz).
