Vostok Amphibia watches are appreciated for their reliability, solid construction, and consistent performance in demanding environments.
PRODUCT DESCRIPTION & FEATURES
This Amphibia model is a mechanical automatic watch featuring a GMT-style time display system. The GMT hand is not independently adjustable; instead, it is 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 method inspired by early GMT designs such as the original Rolex GMT-Master.
