Common Spare Parts and Components
Mainspring and Barrel: Critical for stable power delivery; must match exact dimensions to maintain consistent torque.
Balance Wheel and Balance Staff: Delicate and essential for timing accuracy; include shock protection and require precise compatible replacements.
Pallet Fork and Escape Wheel: Wear-prone escapement parts; original or high-quality NOS parts ensure smooth operation.
Gear Train Wheels: Center, third, and seconds wheels may need replacement due to wear; often sourced from donor movements or NOS stock.
Setting Mechanism: Stem, crown, setting levers, and springs must fit perfectly for reliable winding and time-setting.
Jewels: Synthetic ruby bearings reduce friction; replacements must conform to original configuration for performance and durability.
Hands and Dial Components: Period-correct parts maintain original appearance and collector value.
Sourcing and Maintenance Tips
Prioritize original or NOS parts explicitly marked for AS 1526 or AS 1525 for guaranteed compatibility.
Donor movements are valuable for rare or worn components such as balance assemblies and gear wheels.
Handle delicate parts like the balance and escapement with care during maintenance.
Apply modern synthetic watch oils sparingly, following vintage lubrication standards to maximize movement longevity.
Always verify the calibre number stamped on the main plate before ordering to avoid ordering incompatible parts.

Preserving genuine or precise compatible parts ensures the calibre’s renowned accuracy and reliable manual winding performance.
Correct restoration maintains the vintage watch’s authenticity and collector appeal.
