PRODUCT DESCRIPTION & FEATURES
This Vostok Komandirskie 650539 is a robust mechanical wristwatch designed for durability, strong water resistance, and dual-time functionality. It features an automatic movement with overwind protection, a stainless steel construction, and a GMT-style 24-hour hand system with a rotating bezel.
The GMT hand on this model is not independently adjustable. Instead, it is mechanically linked (“slaved”) to the main hour hand, meaning both move together. A second time zone is tracked by rotating the bezel to offset the time difference, a design approach similar to early GMT watches such as the original Rolex GMT Master.
