Examined by yours truly, a specialist in antique and vintage watches since 1971. Worn by me personally, operates great, has nice features for resetting chronograph hands if ever out of place, top of bezel had picked up a few scratches that I reduced and refinished on my lathe, some remnants remain without cutting - please see new photos.
