A. Schild (AS) Calibre 1816 Watch Spare Parts: Technical Overview and Sourcing Guide
A. Schild (AS) Calibre 1816 is a Swiss automatic mechanical movement introduced around 1965, recognized for its robust construction and inclusion of both day and date complications (day at 6 o’clock, date set by changing the time between 20:00 and 24:00). The movement measures 11.5 lignes (25.60mm) in diameter and around 5.95mm in height, available in 17 or 21 jewel variants and operates at 18,000 vibrations per hour (vph).

Common Spare Parts and Components
Mainspring and Barrel: Crucial for steady power delivery; NOS (new-old-stock) mainsprings and barrels (e.g., Part No. 182) are available.
Balance Wheel and Balance Staff: Precision parts vital for accurate timekeeping; require perfect fit for shock resistance and reliability.
Rotor Assembly and Bearings: Core to the automatic winding mechanism; ensure replacements are genuine or high-quality NOS for smooth winding.
Pallet Fork and Escape Wheel: Wear-prone; sourcing original or NOS parts maintains escapement integrity.
Gear Train Wheels (Minute, Third, Fourth): Frequently replaced due to wear or damage; commonly sourced from donor movements or parts stock.
Setting Mechanism (Stem, Crown, Levers, Springs): Must match original dimensions for winding, time, and date setting functions.
Jewels: Synthetic rubies designed to reduce friction; replacements must exactly follow the original configuration.
Hands and Dial Components: Period-correct spares (e.g., 1.50 x 0.90 x 0.21mm) uphold vintage authenticity and value.
Sourcing and Maintenance Tips
Always use original, NOS, or donor parts specifically marked for AS 1816 to safeguard compatibility and movement quality.
Handle delicate components like the balance, escapement, and rotor assembly with special care during service.
Apply synthetic watch oils sparingly, adhering to vintage lubrication standards for longevity.
Always confirm the calibre number stamped on the main plate before ordering parts to prevent misfits.
Donor AS 1816 movements are invaluable for sourcing rare or worn parts.
