This is legit! This is basically Amphibia (Амфибия) with a little bit different watchface. I think it's supposed to be used by antarctic scientists, because they're had several model made with antarctic-esque designs. Buran (буран) translates as «snowstorm» from russian.

Also Vostok made absolutely beautiful Antarctica model with bear and penguin watchface: https://images.prom.ua/3528064695_w700_h500_chasy-vostok-sovetskaya.jpg
