For sale is my IWC Ingenieur Chronograph Racer Flyback IW378507 The watch comes FULL SET with Box and Papers, and an additional OEM rubber strap (on top of the base leather one). The watch is in overall very good condition. It has a few hairline scratches on the case and bezel, but it has never been polished so it retains its shine and crisp bevels. Timekeeping is fantastic at less than 2 seconds a day of gain when I wear it. Shipping CONUS only for $5200, wire or Zelle. Not interested in trades at this time, thank you (unless one I cannot refuse). Feel free to contact me for any question! Edit: motivated seller, will consider best offers
