Common Spare Parts and Components
Mainspring and Barrel: Essential for energy storage and smooth power delivery; replacements must precisely match original specs to maintain consistent torque.
Balance Wheel and Balance Staff: Critical for accurate timekeeping and shock resistance; require precise fit and high-quality replacements.
Rotor Assembly and Bearings: Integral to automatic winding; rotor bearings or axle replacements must be compatible to maintain winding efficiency.
Pallet Fork and Escape Wheel: Wear-prone escapement components; sourcing original or trusted new-old-stock (NOS) parts helps ensure reliability.
Gear Train Wheels (Minute, Third, Fourth): Often subject to wear or damage; donor movements and NOS parts are typical sources.
Setting Mechanism (Stem, Crown, Levers, Springs): Necessary for smooth winding, time, and date setting; must fit AS 1590 specifications exactly.
Jewels: Synthetic ruby bearings arranged to reduce friction; replacements must match original count and placement.
Hands and Dial Components: Period-correct parts help preserve vintage authenticity and collector appeal.
Sourcing and Maintenance Tips
Prefer original, NOS, or donor parts explicitly designated for AS 1590 to guarantee compatibility and authenticity.
Donor AS 1590 movements serve as valuable resources for rare or worn components.
Handle delicate parts like the balance wheel, rotor assembly, and escapement carefully during servicing.
Use modern synthetic watch oils sparingly and adhere to vintage lubrication standards to extend movement life.
Always verify the calibre number stamped on the main plate before ordering spare parts to avoid mismatches.
