The Omega Pre-Seamaster Ref. 2504-9 is a captivating piece that represents Omega’s early dive into creating elegant, durable timepieces that would later influence the iconic Seamaster line. Powered by the Omega Caliber 283, part of the renowned 30mm manual-winding series, this movement is known for its reliability and precision. The Pre-Seamaster models are celebrated for their role in shaping Omega’s future dive watches, offering both style and substance in a compact form. This specific reference, dating back to the 1940s-50s, showcases the brand’s commitment to excellence and mechanical innovation during the post-war era.

The watch features a charmingly patinated dial, with warm cream tones that have developed over time, adding to its vintage allure. Its 36mm stainless steel case offers a balanced, understated presence on the wrist, while the dial’s Arabic numerals at 12, 3, 6, and 9 o’clock create a clear and symmetrical layout. The sharp dauphine hands retain their polished appeal, standing out against the aged dial. Paired with a soft blue suede strap and the original Omega buckle, this timepiece exudes both vintage character and modern-day wearability.

Brand Story

Omega, founded in 1848 by Louis Brandt in La Chaux-de-Fonds, Switzerland, quickly rose to prominence for its precision and innovation in watchmaking. Originally known as "La Generale Watch Co.," the company rebranded as Omega in 1903 after its groundbreaking “Omega” caliber became a symbol of reliability and precision, setting a new standard for timekeeping. Omega’s commitment to quality and groundbreaking technology has made it a household name, particularly with innovations in chronometry, co-axial escapements, and anti-magnetic materials. One of the defining moments for Omega came in 1932, when it became the official timekeeper for the Olympic Games, a role it has upheld across multiple decades. However, it was in 1969 that Omega truly made history as the first watch brand to reach the moon. Astronaut Buzz Aldrin wore the Omega Speedmaster Professional on his wrist during the Apollo 11 mission, solidifying Omega's place in space exploration. This iconic association with NASA and the Speedmaster’s robust design helped Omega earn a reputation for rugged precision under extreme conditions. Today, Omega is celebrated for both its historical achievements and its modern innovations. Known for models like the Speedmaster, Seamaster, and Constellation, Omega continues to push the boundaries of horological design while remaining a staple among professionals, astronauts, divers, and watch enthusiasts worldwide.
