This is one of two (other sold) Poljot chronographs we leased to the Apple T.V.+ show “For All Mankind” and was worm by Russian pilots on the show. This watch is extremely clean overall. The manual winding movement was cleaned last year and is accurate and functioning perfectly. Notice the stunning original dial with vibrant lume and reflective chrono registers. The 40mm. case is superb and retains its original brushed finish. This one is as good as it gets.
