Common Spare Parts and Service Components
Mainspring and Barrel: Vital for energy storage; must be precisely sized to ensure consistent power delivery.

Pallet Fork and Escape Wheel: Wear-prone escapement components; original or compatible parts ensure continued smooth operation.
Gear Train Wheels (Minute, Third, Fourth): Replacement necessary if teeth or pivots wear; sourced from donor movements or new-old-stock (NOS) parts.
Setting Mechanism (Stem, Crown, Levers, Springs): Essential for reliable manual winding and time-setting; compatibility with AS 1382 dimensions is critical.
Jewels: Synthetic ruby bearings reduce friction; replacements must match exact count and location within the movement.
Power Reserve Indicator Components: Specific parts related to the reserve indicator require proper sourcing for full functional restoration.
Hands and Dial Components: Period-correct parts maintain the vintage authenticity and must fit the unique configuration of the AS 1382.
Sourcing and Maintenance Tips
Use original or NOS spare parts clearly marked for AS 1382 to maintain authenticity and precision fit.
Donor movements are invaluable for rare or difficult-to-find components, especially power reserve parts.
Handle balance, escapement, and rotor assemblies carefully due to their delicate nature and anti-shock features.
Apply modern synthetic watch oils sparingly, following vintage movement lubrication standards to prolong movement life.
Verify the calibre number stamped on the main plate before ordering parts to ensure compatibility.

Maintaining genuine or precise compatible parts preserves the movement’s accuracy, robustness, and unique features such as the power reserve.
Proper parts ensure the watch functions reliably and authentically, upholding collector and repair value.
AS 1382’s combination of automatic winding with power reserve and hacking seconds makes it an important mid-20th-century calibre; quality parts sourcing supports its sustained restoration and use.
