Vostok Amphibian Tonneau Diver's wrist watch, made in USSR, ca.late 1970s.

Vostok amphibian watch is one of the earliest of its kind. The case is stainless steel with bilateral turning bezel.
The dial is navy blue and has raised markers. Hands and second hand are original to the watch. The dots above the markers and hands have been relumed by myself. The watch has been powered with a Vostok 2209 calibre 18 jewel, glucydur balance wheel movement which is typical to this model and of the period. The back case has been inscribed with USSR quality symbol "k" and waterproof to 200M.
