About this watch

When it comes to luxury watches, few brands stand out like Omega. Known for their precision, style, and innovation, Omega has a legacy that dates back to the 19th century. Among their impressive lineup, the Omega Constellation Co-Axial 38 (Model: 123.20.38.21.02.006) combines stunning aesthetics with exceptional mechanical performance. The Omega Constellation series is iconic, often recognized for its classic design and robust engineering. This watch features a blend of stainless steel and yellow gold, which not only enhances its visual appeal but also signifies luxury. With a 38mm diameter, it strikes a perfect balance between being bold yet understated. At the heart of the Constellation Co-Axial 38 is the Omega caliber 8500, a movement that has earned significant respect in the watch community. Introduced in 2007, this automatic movement features a Co-Axial escapement, a technology that enhances precision and reduces friction between components. This means not only better accuracy but also less maintenance over time. As a chronometer, the Omega Constellation Co-Axial 38 has undergone rigorous testing to ensure it meets the high standards set by the Swiss Official Chronometer Testing Institute (COSC). This certification guarantees accuracy within a few seconds per day, making it a reliable companion for anyone who values punctuality. The watch features a date function, water resistance of 100 meters, and an adjustable bracelet for a personalized fit. With its rich history and advanced technology, this watch is sure to become a cherished part of your collection for years to come.
