The BN-1 (БН-1) is the legendary standard-issue naval binocular of the Soviet Navy and Merchant Marine. Designed for the harshest conditions at sea, these were built to withstand freezing spray, saltwater corrosion, and the brutal recoil of shipboard life.
Manufactured by the two absolute giants of Soviet optical engineering – BAIGISH (Minsk Mechanical Plant, Belarus) and KOMZ (Kazan Optical-Mechanical Plant, Russia) – these binoculars represent the very best of Cold War optics. The 7x50 configuration is universally recognized by mariners and astronomers as the perfect balance: bright enough for twilight observation, stable enough for handheld use on a rolling deck, and rugged enough to outlast its owner.
This particular unit is New Old Stock (NOS) – fresh from Soviet military storage, never used, complete with all original accessories. Whether you are a serious collector, a maritime enthusiast, or just want the most indestructible binoculars ever made, this is the real Soviet deal – not a cheap modern replica.

Optics: Fully multi-coated Soviet glass – clean, clear, no haze, no fungus, no scratches.
