Belt model. The Longines Pioneer has released a flyback chronograph watch with a diameter of 42mm. The bezel is bi-directionally rotating with a glossy finish and features strong luminous Arabic numerals separated by small black holes, in sync with the official website. The dial is available in black and blue, with the chronograph sub-dial at 3 o'clock and the small seconds at 9 o'clock. The central large second hand functions as the chronograph's main second hand, and the 6 o'clock position on the dial indicates the flyback function, making it a very convenient chronograph. The sapphire crystal is slightly domed and has anti-reflective coating on both the inner and outer surfaces. The bi-directional rotation is precise and smooth, and the watch is equipped with a screw-down crown that is easy to grip and adjust. The sealed case back is secured by six screws and boasts excellent water resistance of up to 100 meters. The watch features a stainless steel bracelet along with a calfskin leather strap and a NATO blue fabric strap in different versions. It comes with an original folding clasp suitable for various style preferences. Additionally, it is powered by the original L791.4 automatic movement, which provides a power reserve of up to 68 hours.
