2PCS Ronda 1013-21, 1113-21, 1213-21, 1313-21 Cannon Pinion No.2 Part No. 245 Swiss Watch.

Ronda cannon pinion 245 is a replacement motion work component designed for Ronda 1013-21, 1113-21, 1213-21, and 1313-21 Swiss watch movements. This listing includes 2 pieces, making it suitable for watchmakers, repair workshops, collectors, and technicians who require spare components for servicing multiple movements.The ronda cannon pinion 245 is one of the most important components within the motion work assembly. It is mounted on the center wheel arbor and acts as the connection between the gear train and the display system of the watch. The cannon pinion transfers rotational motion from the movement to the hands while allowing the hands to be adjusted through the crown during time-setting operations.Because the cannon pinion operates under continuous friction and mechanical load, it is considered a wear-sensitive component. Over time, wear may affect its friction characteristics, resulting in hand slippage, inaccurate time indication, or difficulties during hand-setting. Replacing worn cannon pinions is a common procedure during professional movement servicing.The ronda cannon pinion 245 is manufactured according to the specifications required by compatible Ronda calibers, ensuring proper fitment and reliable performance when installed correctly.◼️ Ronda Cannon Pinion 245 FunctionThe ronda cannon pinion 245 performs several critical functions inside the movement.Its primary responsibilities include:Transferring motion to the minute handSupporting the motion work assemblyMaintaining accurate hand synchronizationAllowing smooth hand-setting through the crownProviding the correct friction fit required for operationThe cannon pinion is responsible for ensuring that the display system remains synchronized with the movement.Without proper operation of this component, the watch may lose accuracy in hand positioning even if the movement itself is functioning correctly.◼️ Ronda Cannon Pinion 245 ConstructionThe ronda cannon pinion 245 is manufactured with precise tolerances to ensure compatibility with the specified Ronda movements.It operates together with:Center wheelMinute wheelHour wheelMotion work assemblyHand-setting mechanismThe design provides the correct friction level required for both normal operation and manual adjustment of the hands.Proper fitment helps reduce wear and ensures smooth transmission of motion.Using the correct cannon pinion helps preserve the original mechanical characteristics of the movement.◼️ Ronda Cannon Pinion 245 Use in RepairThe ronda cannon pinion 245 is commonly used during:Watch repairMotion work servicingHand-setting mechanism repairMovement restorationComplete movement overhaulProfessional watchmakers frequently inspect the cannon pinion during servicing because wear in this component can directly affect time display accuracy.Before installation, it is important to verify:Movement caliber compatibilityPart number (245)Condition of the center wheelCondition of surrounding motion work componentsProper installation ensures reliable operation and long-term performance.◼️ Compatible Ronda MovementsThe ronda cannon pinion 245 is compatible with:Ronda 1013-21Ronda 1113-21Ronda 1213-21Ronda 1313-21Always verify movement reference before installation.Using the correct caliber ensures proper fitment and functionality.◼️ Benefits of a 2PCS SetThis listing includes two cannon pinions, providing additional flexibility for repair professionals and watchmakers.Advantages include:Spare part availabilityServicing multiple movementsWorkshop inventory supportBackup component for future repairsCost-effective replacement solutionHaving spare motion work components available helps reduce repair delays and improve workshop efficiency.◼️ Ronda Cannon Pinion 245 ReliabilityThe ronda cannon pinion 245 is designed to restore proper motion work performance when replacing a worn or damaged original component.When correctly installed, it provides:Accurate hand movementSmooth hand-settingReliable motion transmissionStable display performanceLong-term functionalityRoutine servicing and proper maintenance help maximize the lifespan of the motion work system and reduce wear on surrounding components.The cannon pinion remains one of the most important components within the hand-setting mechanism and contributes directly to the accuracy and reliability of the watch.◼️ Shipping & Delivery Phone & WhatsApp: 20 122 323 9604Email: [email protected]Email: [email protected]Website: www.swisswh.comFacebook: https://www.facebook.com/WatchHouseSpareParts
