Common Spare Parts and Components
Mainspring and Barrel: Crucial for energy storage and stable power delivery; must exactly match original specifications for reliable operation.

Rotor Assembly and Bearings: Vital for efficient automatic winding; bearing or axle wear requires careful servicing or replacement with compatible parts.
Pallet Fork and Escape Wheel: Key escapement components subject to wear; sourcing original or new-old-stock (NOS) parts is important to ensure smooth function.
Gear Train Wheels (Minute, Third, Fourth): Commonly replaced due to wear; often sourced from donor movements or NOS stock.
Setting Components (Stem, Crown, Levers, Springs): Must fit exactly for reliable winding, time-setting, and automatic winding functionalities.
Jewels: Synthetic ruby bearings reduce friction and wear; replacements must correspond to original count and positioning.
Hands and Dial Components: Period-correct parts help preserve vintage authenticity during restoration.
Sourcing and Maintenance Tips
Prioritize original or NOS parts explicitly marked for AS 1533 to maintain authenticity and compatibility.
Donor movements are invaluable sources for rare or worn components such as rotor assemblies and escapement parts.
Handle delicate parts, especially the balance wheel and rotor assembly, with care during servicing.
Use modern synthetic watch oils sparingly, adhering to vintage lubrication standards for longevity and performance.
Always verify the calibre number stamped on the main plate before ordering parts to avoid incompatibility.
