ETA Caliber 2472 Technical Specifications and Parts
Technical specifications and service documentation for the ETA caliber 2472 automatic watch movement. This workshop manual provides detailed technical data including precise millimeter dimensions for all major components: balance wheel and hairspring assembly, escapement mechanism, barrel and mainspring, gear train, and supporting structures like the cage, virole, and piton. The guide features exploded diagrams showing the complete movement architecture, complemented by comprehensive parts lists covering both the base caliber 2450 platform and all caliber 2472-specific components. Each part is cross-referenced with its part number and nomenclature in French, English, and German for international technical reference. The movement specification covers the automatic winding system, direct-drive seconds hand, and instantaneous date mechanism accessed through the dial window—essential information for watchmakers, repair technicians, and horological professionals performing maintenance, repair, or restoration work on this movement.
