Raketa Cal. 2609

The Raketa 2609 caliber, introduced in the 1960s, is a manual wind mechanical movement that became a cornerstone of the Petrodvorets Watch Factory’s production, powering numerous Raketa models, including the iconic Big Zero and Copernicus. This 19-jewel movement operates at 18,000 beats per hour and offers a power reserve of approximately 42 hours, delivering reliable timekeeping for its era. Measuring 26mm in diameter and 3.6mm in height, it features a robust design with a pallet lever escapement and a balance wheel, typically without shock protection in early versions, though later iterations may include it. The 2609.HA variant, stamped “SU” for Soviet Union, is particularly noted for its durability, often described as one of the most rugged Soviet calibers due to its ability to withstand harsh conditions, as seen in watches supplied to the Red Army and Soviet Navy. Its straightforward construction facilitates easy servicing, making it a favorite among watchmakers and collectors. The movement’s versatility allowed it to be adapted for various dial designs, from minimalist dress watches to bold models like the Big Zero, and its continued functionality in well-maintained examples underscores its engineering quality. Collectors value the 2609 for its historical significance and mechanical charm, with market listings highlighting its presence in watches priced from $50 to $200, reflecting its accessibility and enduring appeal in the vintage watch community.
