Speedmaster Reduced... better than the Moonwatch?

Updated: Apr 20, 2022

In the late 1980's, Omega decided to put a diminutive variation of their flag bearer, the Speedmaster Professional, into the market.

In 1988, Omega launched the Speedmaster Automatic, nicknamed "Reduced" because of its smaller 39mm case size. Omega fit a Calibre 1140 movement, essentially, Omega's own assembly of an ETA 2890-2 with a Dubois-Dépraz 2020 chronograph module mounted to the dial-side.

From a distance, the Speedmaster Automatic with its black dial and familiar case can be mistaken for its big brother, the Speedmaster Professional. Upon closer inspection, you will notice details that differentiate it. The most obvious being that the "Reduced" dial reads "Automatic" rather than "Professional". The vast amount of space from the central pinion to the sub-dials at 3 & 9 is another detail that differentiate the "Reduced" from the "Professional".

There are plenty more details that make the "Reduced" different from the "Professional" but that is for another day, an in-depth video review perhaps!

The smaller case size and fully automatic movement make this an almost perfect watch! This is not something I say lightly, I really believe that the "Reduced" is a slightly better option for most. Lets hope that Omega re-introduce a variation of the Speedmaster Automatic, because I for one would be first in line.
