About the product: About the product Manufacturer Omega Model Speedmaster Professional Ref. ST145.022 Stainless Steel 1991 Ser.4826 Long R Moon Bezel Movement Hand Wound Cal.861 Case Steel (SS) 42mm Bracelet Strap Omega NASA Strap [Slightly Usable] Accessories No Accessories Dial Black Overall condition: small scratches (can be removed by polishing) [overhauled] Comment I am a Speedmaster professional, Omega's main model. It is famous as a watch that went to Apollo and the Moon in 1969, and it is a model that has withstood harsh NASA tests. The rotor is a risk for testing, and since there is no gravity and it is useless in outer space, it is hand-wound. The basic design of the Speedmaster Professional has not changed since the 4th model, including the current model. While automatic windings are becoming popular, it is equipped with a Lemania hand-wound chronograph Cal.861, the same as in the past, so you can feel Omega's thoughts. Unlike the previous Cal.321, the chronograph's switching mechanism uses a cam type, and the balance is changed to a flat beard and smooth steel. Also, the frequency has increased from 18,000 vibrations per hour to 21800 vibrations per hour. This is the model Ref.ST145.022 before the serial number was engraved on the back of the 1991 lug, and the dial is a long R with R lowered. The bezel has faded like the surface of the moon in a gray world due to moon dust, and the one wearing an Omega NATO strap is the moonwatch itself that has returned from a mission in space. It makes me feel the majesty of a battle history that has overcome various missions that cannot be tolerated by ordinary people.
