Known for its robustness and exceptional water-resistance, this men's timepiece from the Spirotechnique collection is signed by the legendary Auricoste watchmaking house. Designed for the French Navy's combat swimmers, this diving watch offers sober, elegant aeronautical styling and unrivalled reliability. The case is in 316L stainless steel. Topped with a sapphire crystal, the case measures 42mm in diameter by 13.30mm thick, and features a black unidirectional rotating bezel. The bezel is graduated with white indexes, dots and numbers 10, 20, 30, 40 and 50. Finally, the caseback is screw-down, as is the winding crown located at 4 o'clock and protected by a part of the case.
