A true grail! I found this gem in non-working condition. A very early Cyrillic Strela with serial number 0321. One of the first Strela watches that came out of the factory in 1959. 

​

After sending it to the watchmakers it came back in full running condition like it left the factory. When the sunlight hits the dial it gets that remarkable glow and makes the blue second hand shine like the sun. This one is hard to beat!
