A. Schild (AS) Calibre 1861 is a vintage Swiss manual-wind mechanical chronograph movement known for its precision, reliability, and classic design.

Proper maintenance with quality spare parts is essential for preserving these vintage timepieces.

Common Spare Parts and Components
Mainspring and Barrel: Critical for steady and reliable power delivery; original or NOS mainsprings ensure consistent torque and durability.
Balance Wheel and Balance Staff: Precise components needed for accurate timekeeping and shock resilience; replacements must be exact fits.
Chronograph Mechanism Parts: Include column wheel, coupling lever, chronograph brake (often made from Delrin or similar polymers), and minute recorder components; high-quality parts critical for smooth chrono operation.
Pallet Fork and Escape Wheel: Wear-prone escapement parts; sourcing original or NOS components maintains smooth and reliable operation.
Gear Train Wheels (Minute, Third, Fourth): Frequently replaced due to wear or damage; typically sourced from donor movements or NOS stock.
Setting Mechanism (Stem, Crown, Levers, Springs): Accurate fitting parts essential for smooth winding, time setting, and chronograph controls.
Jewels: Synthetic ruby bearings arranged to minimize friction; replacements should match original layout exactly.
Hands and Dial Components: Period-appropriate parts preserve vintage authenticity and collector appeal.
Sourcing and Maintenance Tips
Use original, NOS, or donor parts clearly marked for AS 1861 or compatible vintage chronograph calibers to ensure proper compatibility.
Handle fragile chronograph components and balance assemblies with care during servicing.
Apply modern synthetic watch oils sparingly, following vintage lubrication standards to optimize performance and longevity.
Always 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 valuable sources for rare or worn components.
