Rare chronograph, originally produced in a limited edition of 80 copies, with a large second, this one with a red second was the prototype of the series. Movement: Swiss mechanical self-winding caliber TOT / VALJOUX 7750. Sold to members of the GIGN (National Gendarmerie Intervention Group) as a tribute to their air transport protection work known as 'Sky Marshall'. It comes from the personal collection of the brand's creator, engineer René Bruyeron. The steel case features a large aperture, a smooth stepped bezel, and a domed, screw-down sapphire crystal case back (signed, numbered and inscribed with the GIGN logo). The black dial bears the GIGN logo at 9 o'clock and the red "Sky Marshall" lettering. Three sub-dials are displayed: the small seconds at 9 o'clock, the minute at 12 o'clock and the hours, along with a date window at 6 o'clock. Arabic numerals and skeleton hands with Luminova provide night vision.
