Collectors prioritize this reference for its 51mm chrome-plated base metal case and its unique 41-degree offset dial, designed to allow pilots to read the time without releasing flight controls. The watch contains the caliber 18.72 manual-wind monopusher chronograph movement. Due to the corrosive nature of the chrome plating and the rigors of military use, examples in original, well-preserved condition are rare. On the secondary market, these timepieces typically command prices between $20,000 and $40,000 depending on provenance and dial state. A notable production detail is the \"U.S. Army A.C.\" engraving on the caseback, which distinguishes authentic military issues from civilian counterparts. A high-quality example sold at a 2017 Phillips auction for approximately 32,500 CHF.", "score": 200}]}
