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!
I don't think Vostocks get enough love in this sub. That's a great looking watch.
