Vostok hand-wound wristwatch Silver dial with red numerals and hands Features a battleship design My father bought this on an overseas business trip and it was kept at home. I tried winding it, but it doesn't seem to be working. I don't know if I'm doing it wrong or if it's broken. The hands move smoothly. Below is the description from Google Lens: This is a military watch "Komandirskie" from the Russian watchmaker "Vostok". It is a model derived from the diver's watch "Amphibia" developed for the Soviet Navy. The dial features a ship and anchor mark, indicating a design for the navy. It is a hand-wound mechanical watch with a rotating bezel. It is believed to be a product from the 1980s to 1990s of the Soviet Union era. - Brand: Vostok - Color: Silver - Features: Hand-wound - Design: Battleship design - Dial: Red numerals and hands - Size: Approximately 40mm Thank you for viewing.
