A. Schild (AS) Calibre 1402 Watch Spare Parts: Technical Overview and Sourcing Guide
A. Schild (AS) Calibre 1402 is a vintage Swiss automatic mechanical movement derived from the AS 1361 calibre, enhanced with calendar and moon phase complications. Produced around the 1950s, this movement is well-regarded for its sturdy automatic winding system combined with useful additional functions, making it a prized movement for collectors and watchmakers restoring mid-20th-century wristwatches.
Key Technical Highlights
Calibre: AS 1402
Movement Type: Automatic winding mechanical with calendar and moon phase complications
Diameter: 26 mm (11.5 lignes)
Jewels: Usually 17 or 21 synthetic ruby jewels
Beat Rate: 18,000 vibrations per hour (vph)
Power Reserve: Approximately 38 hours
Functions: Hours, minutes, sweep seconds, calendar with date display, moon phase indicator
Shock Protection: Incorporated anti-shock system typical of the era
Additional Info: Based on AS 1361 with added calendar and moon phase mechanisms
Common Spare Parts and Service Components
Mainspring and Barrel: Critical for stable power delivery; must be matched precisely for durability and consistency.
Balance Wheel and Balance Staff: Vital for timing accuracy; subject to shock damage necessitating exact replacements compatible with the movement’s shock protection.
Rotor Assembly and Bearings: Essential for automatic winding functionality; wear here affects winding efficiency and requires specialized parts.
Pallet Fork and Escape Wheel: Frequently serviced escapement components; original or compatible parts ensure smooth operation.
Calendar and Moon Phase Mechanism Parts: Date wheels, moon phase discs, springs, pushers, and cams are vital for full functional restoration of complications.
Wheels (Minute, Third, Fourth): Transmission gears prone to tooth or pivot wear; replacement parts often sourced from donor movements or new-old-stock (NOS).
Setting Mechanism (Stem, Crown, Setting Levers, Springs): Crucial for winding, time setting, and calendar adjustment; precise matching parts required.
Jewels: Synthetic ruby bearings matching the original count and position reduce friction and wear.
Hands and Dial: Period-correct hands and dials maintain authenticity and collector appeal.
Sourcing and Maintenance Tips
Prioritize original or NOS parts labeled for AS 1402 to guarantee perfect fit and maintain authenticity.
Donor AS 1402 movements are invaluable for sourcing rare components, especially calendar and moon phase parts.
Handle delicate assemblies such as the balance wheel, rotor, and calendar mechanisms carefully during servicing.
Use modern synthetic watch oils sparingly, following traditional lubrication standards to maximize longevity.
Confirm the calibre number stamped on the main plate before ordering parts to ensure compatibility.
Why AS 1402 Spare Parts Matter
Preserves Movement Complexity: Genuine parts maintain the accuracy and reliable automatic winding plus calendar and moon phase functions.
Collector and Repair Value: Authentic restoration preserves the vintage integrity and value of the watch.
Watchmaker Familiarity: The AS 1402 is well-documented, enabling effective servicing and parts sourcing in the restoration community.
The A. Schild AS 1402 calibre symbolizes a sophisticated mid-20th-century automatic Swiss movement where precise spare parts sourcing is essential for sustaining its legacy of reliability and functional elegance.
