Explanation for the rest.
During the cold war period, the soviet Mod had a quality asurance office on the premises of the Vostok plant.
The watches which passed this office were intended for military service and the dials bore the blurp: 3aka3 mo cccp

giving rise to desireable ´3aka3´ or zakaz Vostoks.
It simply stands for ´in order of´ hence it features on the 2415 caliber I ordered. Still a fun association with the vintage coolskies.
