ETA 6325 Ratchet WheelThe ETA 6325 Ratchet Wheel is a genuine Swiss replacement component manufactured specifically for the ETA/UNITAS 6325 manual wind movement. According to the official ETA/UNITAS parts catalogue, Part No. 415 is identified as the Ratchet Wheel, one of the primary components of the manual winding mechanism responsible for transmitting rotational force from the crown to the mainspring barrel.Manufactured to original Swiss factory specifications, the ETA 6325 Ratchet Wheel is precision-machined to ensure smooth engagement with the crown wheel and secure attachment to the barrel arbor. During manual winding, it transfers torque generated by the winding stem through the winding train into the mainspring, allowing the watch to store the energy required for continuous operation.The winding system is one of the most heavily used mechanical assemblies within a manual watch. Every time the crown is turned, the ETA 6325 Ratchet Wheel rotates to wind the mainspring while working together with the click and click spring to prevent reverse movement. This mechanism safely locks the stored energy inside the mainspring barrel until it is gradually released through the gear train.A worn, damaged, or excessively worn ETA 6325 Ratchet Wheel may result in slipping during winding, rough crown operation, reduced winding efficiency, or premature wear of the surrounding winding components. Installing a genuine Swiss replacement restores smooth winding action and maintains the original mechanical performance of the movement.Professional watchmakers choose genuine ETA/UNITAS replacement parts because every component of the winding mechanism must be manufactured with extremely tight tolerances. The ETA 6325 Ratchet Wheel is produced using hardened Swiss steel for excellent strength, wear resistance, and long-term durability under thousands of winding cycles. Its precise tooth profile ensures smooth engagement with the crown wheel while minimizing friction and mechanical wear.The ETA/UNITAS 6325 remains one of the most respected vintage Swiss manual wind calibers thanks to its robust construction and dependable engineering. Preserving this movement with authentic replacement components such as the ETA 6325 Ratchet Wheel helps maintain originality, collector value, and factory-level reliability throughout future servicing.Whether you are performing a complete movement overhaul, replacing worn winding components, or restoring a vintage Swiss watch, the ETA 6325 Ratchet Wheel delivers the quality, precision, and durability expected from genuine Swiss watch parts. Its factory-quality construction and accurate dimensions make it the preferred choice for professional repair workshops, restoration specialists, and collectors seeking authentic ETA/UNITAS replacement components.Technical SpecificationsBrand: ETA / UNITASCaliber: 6325Part Name: Ratchet WheelPart Number: 415Movement Type: Manual WindSwiss MadeGenuine Swiss Replacement PartCondition: NOS (New Old Stock)FeaturesGenuine ETA / UNITAS partOriginal Swiss Made componentRatchet Wheel Part No. 415Precision-machined hardened steelAccurate factory dimensionsSmooth manual winding performanceReliable power transmissionProfessional repair qualityIdeal for vintage movement restorationLong service lifeFunction and PurposeThe ETA 6325 Ratchet Wheel transfers winding force from the crown wheel to the mainspring barrel, allowing the movement to store energy during manual winding.
