Gear Train Wheels (Minute, Third, Fourth): Often replaced due to wear; typically sourced from donor movements or NOS stock.
Setting Mechanism (Stem, Crown, Levers, Springs): Must fit precisely to guarantee reliable winding and time adjustment.
Jewels: Synthetic ruby bearings positioned to reduce friction; replacements must match original count and placement.
Hands and Dial Components: Period-correct parts preserve vintage authenticity and collector value.
Sourcing and Maintenance Tips
Use original, NOS, or donor parts clearly marked for AS 1700 to ensure compatibility and retain movement integrity.
Handle delicate parts like the balance and rotor assemblies with care during servicing.
Apply modern synthetic watch oils sparingly, adhering to vintage lubrication standards for durability and performance.
Always verify the calibre number stamped on the main plate before ordering spare parts to avoid mismatches.
Donor movements provide valuable source parts for hard-to-find or worn components.
