Flying Tourbillon! Men's hand-wound... A used men's wristwatch made by Liaoning. The watch itself only, no accessories. Comes with a commercially available case. The movement is Liaoning's cal.5010, the well-known one-minute flying tourbillon. It's a hand-wound, two-hand watch with a carriage that serves as the seconds hand, plus a power reserve (50 hours) indicator. The beat rate is 21,600 bph (6 beats per second), a low beat. Currently, it's running at approximately +12 seconds per day. The time graph at the end of the photos is a simple measurement taken while flat, a reference value from a smartphone app. It is not a guaranteed value. The British Horological Institute (BHI) released a 150th-anniversary watch in 2008 that also featured this cal.5010 (as is). While tourbillons are seen on Mercari, many have cluttered and childish designs, or are tourbillon-style (carriage doesn't rotate, just an open heart = pachinko prize level). Genuine ones with a power reserve are not numerous. ◾️Other Notes: The item is stored at home. Please refrain from purchasing if you are sensitive to imperfections or seek perfection.
