ETA SA G10-71A

The G10-71A is a quartz chronograph movement manufactured by ETA SA, introduced in 1997 as part of the company's Fashionline series. It operates with a 4-jewel movement and features sweep seconds chronograph functionality, powered by a 9.5 x 3.6 1.55v battery. The caliber is non-serviceable—ETA does not permit disassembly, limiting maintenance to electrical testing and hand-fitting. Production has been discontinued, and the movement was primarily used in entry-level, lower-priced timepieces.
