Seiko 6106C

The Seiko caliber 6106C is a vintage automatic movement manufactured in Japan during the late 1960s to early 1970s. It features a day-date complication with bilingual day display, distinguishing it from earlier versions in the 6106 family. The movement uses Seiko's Magic Lever winding system and Diashock shock protection, and was produced with 17, 23, or 25 jewels depending on the variant. Production has been discontinued.
