It is powered by the in-house caliber 30CH, a manual-wind movement featuring a column wheel and flyback functionality, which collectors regard as the successor to the 13ZN. This reference is distinguished by its 37.5mm to 38mm waterproof-style case with a screw-down caseback and \"mushroom\" pump pushers. Dials typically feature a two-register layout with various scales, including tachymeter or telemeter tracks. Due to its larger proportions and technical movement, it is a primary target for vintage Longines enthusiasts. On the secondary market, prices generally range from $12,000 to $25,000 depending on condition and dial configuration. A notable production detail is the \"Sunray\" dial variant, which can command premiums at auction, with exceptional examples occasionally exceeding the $30,000 mark in specialized sales.", "score": 199}]}
