A. Schild (AS) Calibre 1130 Watch Spare Parts: Technical Overview and Parts Guide
A. Schild (AS) Calibre 1130 is a legendary Swiss manual-wind movement, widely known for powering military, field, and civilian watches—especially German “Wehrmachtswerk” timepieces—in the mid-20th century.
Technical Highlights
Type: Manual wind, sub-second dial at 6 o’clock
Size: 13 lignes (approx. 29.4 mm diameter)
Thickness: 3.8 mm
Jewels: Commonly 17 (may vary 15–21)
Power Reserve: About 41 hours
Beat Rate: 18,000 vph
Shock Protection: Most have none; late samples occasionally have Incabloc or similar
Special Notes: Also called “Wehrmachtswerk” in German military watches; replaced by AS 1188 for direct sweep second
Common Spare Parts and Service Needs
Mainspring:
Dimensions: approx. 1.70–1.75 mm x 0.130–0.135 mm x 340–360 mm x 11.5 mm
Failures include breakage and loss of tension—replace with correct AS 1130 mainspring
Balance Staff:
Must match shock/non-shock variant (dimensions vary with cap-jewel system)
Prone to breakage, especially in models lacking shock protection
Pallet Fork and Arbor:
Torn, bent, or worn teeth and pivots require replacement. Use AS 1130-specific fork
Wheels (Minute, Third, Fourth):
Look for tooth wear, bent pivots, or corrosion; source from donor movements or NOS parts
Escape Wheel:
Especially for non-shock models, check for wear on pivots and teeth.
Barrel and Ratchet Wheel:
Barrel wear may cause power loss; replace or rebush as needed.
Stem, Crown, and Setting Mechanism:
Issue: Detent screw removal can be tricky; use caution to avoid losing spring and click
Hands and Dial:
Sub-seconds hand hole is unique to this calibre; dials are often military-styled, originals are rare and sought after
Jewels:
17 or 21-jewel variants; match for size and placement if replacing separately.
Incabloc/Other Anti-Shock Parts:
Only late and rare; identify presence/absence before ordering.
Sourcing Strategies
Original Parts:
Use only AS 1130-labeled parts due to variations in arbor, mainspring, and wheel sizes
