Common Spare Parts and Components
Mainspring and Barrel: Provides consistent and reliable power delivery; use original or new-old-stock (NOS) mainsprings for durability and correct torque.
Balance Wheel and Balance Staff: Precision components essential for accurate timing and shock resistance; must be exact fits.
Chronograph Mechanism Parts: Includes column wheel, coupling lever, chronograph brake (commonly made from plastic polymer materials like Delrin), and minute recording components; sourcing genuine or high-quality NOS parts ensures smooth chronograph operation.
Pallet Fork and Escape Wheel: Wear-prone escapement parts; original or NOS components maintain smooth and reliable escapement action.
Gear Train Wheels (Minute, Third, Fourth): Frequently replaced due to natural wear; sourced from donor movements or NOS stock.
Setting Mechanism (Stem, Crown, Levers, Springs): Precisely fitting parts are critical for smooth winding, time setting, and chronograph control.
Jewels: Synthetic ruby bearings arranged to minimize friction; replacements must exactly match the original layout for movement integrity.
Hands and Dial Components: Period-correct parts maintain vintage aesthetics and collector appeal.
Sourcing and Maintenance Tips
Always use original, NOS, or donor parts marked for AS 1861 or compatible vintage chronograph calibers to ensure reliable compatibility and function.
Handle delicate chronograph components and balance assemblies with care during servicing to avoid damage.
Apply modern synthetic watch oils sparingly, following vintage lubrication protocols to optimize longevity and performance.
Verify the calibre number stamped on the movement main plate before ordering parts to avoid mismatches.
Donor AS 1861 or Lemania 1873 movements can be invaluable sources for rare or worn components.
