Common Spare Parts and Service Needs
Mainspring and Barrel: Vital for power delivery; replacement parts must match original dimensions exactly for consistent torque and longevity.

Gear Train Wheels (Minute, Third, Fourth): Often experience wear; typically sourced from donor movements or NOS stock.
Setting Mechanism (Stem, Crown, Levers, Springs): Must fit precisely to ensure reliable winding and time setting.
Jewels: Synthetic ruby bearings positioned to reduce friction; replacements must correspond perfectly to the movement’s original configuration.
Hands and Dial: Period-correct parts enhance authenticity and maintain collector value.
Sourcing and Maintenance Tips
Use original, NOS, or donor parts marked specifically for AS 1511 or the fully interchangeable AS 1510 to guarantee compatibility and authenticity.
Handle balance and escapement components with care owing to their delicacy and the movement’s precision standards.
Apply modern synthetic watch oils sparingly, following vintage lubrication guidelines to optimize longevity and performance.
Always verify the calibre number stamped on the main plate to prevent ordering incompatible parts.
