ETA 6325 Winding StemThe ETA 6325 Winding Stem is a genuine Swiss replacement component manufactured specifically for the ETA/UNITAS 6325 manual wind movement. According to the official ETA/UNITAS spare parts catalogue, Part No. 401 is identified as the Winding Stem, the component that connects the external crown to the internal winding and keyless works mechanism.Manufactured to original Swiss factory specifications, the ETA 6325 Winding Stem is engineered with precision-machined threads and accurate dimensions to ensure perfect compatibility with the original movement. As one of the most frequently operated components in a manual wind watch, the winding stem must withstand repeated winding and hand-setting while maintaining smooth operation throughout its service life.The ETA 6325 Winding Stem performs two essential functions. In its normal position, it transmits rotational force from the crown through the winding pinion and clutch wheel to wind the mainspring. When the crown is pulled into the hand-setting position, the winding stem engages the keyless works, allowing the setting mechanism to adjust the hour and minute hands accurately without interrupting the movement’s mechanical integrity.A damaged, bent, worn, or broken ETA 6325 Winding Stem can cause several operating issues, including difficulty winding the watch, inability to set the time correctly, rough crown operation, or complete loss of connection between the crown and the movement. Replacing the damaged stem with a genuine Swiss replacement restores smooth winding, accurate hand-setting, and reliable crown function.Professional watchmakers rely on authentic ETA/UNITAS spare parts because the keyless works require extremely precise dimensional tolerances. The ETA 6325 Winding Stem is manufactured from high-quality hardened steel, providing excellent resistance to wear, twisting, and repeated daily operation. Its precision machining ensures proper engagement with the winding pinion, clutch wheel, and setting mechanism while preserving factory performance.The ETA/UNITAS 6325 is a respected vintage Swiss manual wind caliber widely appreciated for its robust construction and dependable design. Maintaining this movement with authentic components such as the ETA 6325 Winding Stem helps preserve both its originality and long-term mechanical reliability. Genuine replacement parts provide superior fit, smoother operation, and greater durability compared to generic alternatives.Whether performing a complete movement overhaul, replacing a damaged stem, or restoring a collectible vintage watch, the ETA 6325 Winding Stem offers the precision, durability, and quality expected from genuine Swiss watch components. It is the preferred choice for professional watchmakers, restoration specialists, and collectors seeking authentic ETA/UNITAS replacement parts that maintain factory specifications and dependable long-term performance.Technical SpecificationsBrand: ETA / UNITASCaliber: 6325Part Name: Winding StemPart Number: 401Movement Type: Manual WindSwiss MadeGenuine Swiss Replacement PartCondition: NOS (New Old Stock)FeaturesGenuine ETA / UNITAS partOriginal Swiss Made componentWinding Stem Part No. 401Precision-machined hardened steelAccurate factory dimensionsSmooth winding and hand-settingReliable keyless works operationProfessional repair qualityIdeal for vintage movement restorationLong service lifeFunction and PurposeThe ETA 6325 Winding Stem connects the crown to the movement, transmitting rotational force for manual winding and engaging the keyless works during time-setting.
