Only recently I found out about Vostok when I was looking for an automatic diver style beater watch. The brand has an interesting history and used clever engineering tricks for this particular model, plus it has an in-house movement! The rotating bezel is a little stiff at first but it gets smoother once you use it more, and the NATO strap makes it a perfect daily driver!
Any idea what reference of the Amphibia this is? Great looking watch
