Molnija's main product were mechanical pocket watches with military, religious and historical motifs. The Molnija movement is basically a copy of a Cortébert movement used in Swiss watches from around 1940. About 80% of the work on most of the watches was done by hand. Some Molnija movements were used in oversized men's wristwatches. Early Molnija pocket watch movements (from 1947 to c. 1960) normally had 15 jewels. Later ones (from around 1965 to 1997) normally had 18 jewels. However from around 1997 they started to produce lower quality watches with fewer jewels.
