Question: are vostok watches a good investment?
Answer: Vostok models such as the Amphibia and Komandirskie are good military-grade timepieces. They are very tough, plus, they use 19800 BPH 31 and 32 mechanisms, which are jewel self-winding and shock-resistant. They can operate without requiring maintenance for as long as 10 years – or longer if you use them carefully.
