The Omega Speedmaster Automatic is commonly known as the “Reduced” because it shares the majority of its design with the larger Speedmaster Professional Moonwatch but in a smaller package. Measuring 38.5mm in diameter, the case shares the same twisted lugs with mixed brushed and polished finishing, black tachymeter bezel, and hesalite crystal as the larger Speedmaster Professional. The dial retains a similar layout to its big brother with triple registers and a matte black surface with white printing and luminous hour markers. Where the Reduced also differs is in its movement, as the watch is powered by the Omega 46-jewel caliber 1140 automatic chronograph movement versus the hand-wound unit in the Professional.

This example of the Reference 175.0032 Speedmaster Automatic "Reduced" is in excellent condition and was just serviced in January 2022 by our Omega certified Master Watchmaker. The watch features a beautiful original tritium dial with a very attractive patina on the hour markers and hands, along with a 50.7 million serial number which dates production to the late 1980s during the early production of this watch. The 175.0032 reference predates the more commonly used reference 3510.50 as it uses the older Omega 7 digit reference numbering convention that was updated at the very end of the 80s.
