Hi, I'm selling some watches from my collection. This is a beauty!
It's a vintage Sekonda Strela (Poljot 3017) chronograph wristwatch, a legendary piece of Soviet watchmaking history. 
36mm Chrome plated Case. Champagne Dial, Gold hands and indices.
I have ironically fitted it with a new & unused "Nato" Strap. But it compliments it nicely.
Period appropriate Sekonda Box (Not the one originally supplied with this particular watch)
From Web:- 
Historical Significance: A version Worn by cosmonaut Aleksey Leonov during the first-ever spacewalk in 1965. 
  • Features a rare and desirable 19-jewel, manual-winding, column-wheel chronograph movement (caliber 3017)
  • Produced in the USSR (Union of Soviet Socialist Republics), with Sekonda being the British arm for exporting these watches to the West. 
  • Includes a stopwatch function, a 45-minute counter, and a telemeter scale on the dial. 
  • Collectibility. Due to their historical importance and relatively low production numbers compared to Swiss counterparts, these watches are highly sought after by collectors./* ssgST: excluded from sampling */
