The watch is used, but it is undoubtedly a genuine item purchased by a friend at a famous store. The belt became old, so a few years ago I purchased a genuine belt and buckle on Yahoo Auctions. The original belt was blue, but I changed it to black, which suits it very well and looks cool. I haven't used it much since purchasing it used, but there are some minor scratches. It was overhauled in 2018 at a well-known local repair shop. I will also provide the receipt from that time. All accessories are as shown in the photos. The box is not in a clean condition, possibly due to long-term storage. Please make your judgment based on the photos. As this is a high-value item, please make your purchase after carefully reviewing the photos. Also, to prevent swapping, returns and refunds are not accepted after purchase. Thank you for your understanding. Due to the nature of the item being used, please refrain from purchasing if you are sensitive to imperfections or seek perfection. I am considering purchasing another watch in the long term, so I cannot accommodate significant price reductions. Thank you for your understanding. For detailed information, please search the watch's details online. This is a collaboration model created to commemorate Breitling's partnership with acrobatic flight teams from various countries in the 1990s. This is a collaboration model with the Swiss Air Force acrobatic team "Patrouille Suisse," with a limited edition of 1,000 pieces worldwide. The Patrouille Suisse mark is printed at the 3 o'clock position. The same mark is also engraved on the back cover.
