Luch Luch 1801

Luch 1801 is a small manual-wind caliber introduced in 1960 by the Luch watch manufacturer. Measuring 18mm in diameter, it ranks among the smallest Soviet movements ever produced and was specifically designed for early ladies' watches. Developed entirely in-house as part of the Luch 1800 family, the caliber has remained in continuous production for over six decades. Its compact dimensions and enduring design make it notable within the context of Soviet watchmaking history.
