Supplement to Parts Catalogue/Technical Guide Cal. 3M22A - Power Resource Change
Supplement to the Parts Catalogue and Technical Guide for Seiko caliber 3M21A/3M22A, documenting the transition from the original capacitor unit (3029 011) to an improved rechargeable battery unit (3027 29N). The guide presents a comparative performance matrix tracking indicator display duration and balance wheel swing counts across both power sources, helping technicians understand the operational advantages of the new design. Includes a detailed parts list with identification diagrams and practical installation guidance covering capacitor clamp compatibility. Critical specification: the new rechargeable battery unit and its corresponding clamp assembly must be sourced together as set 3027 3MZ to prevent short circuit risk or internal movement damage during installation and operation.
