The BR-X5 is made from high-tech materials which are lightweight yet robust. Its manufacture movement ensures it soars to the very heights of precision. Inspired by the Aero GT supercar and the design of stealth aircraft, the watch dial adopts the codes of racing car instrument panels. It has a central seconds hand with a chequered graduation accurate to the quarter-second, with the minutes on the outer flange and the hours on the crystal of the dial. The hour numerals and hands are luminescent for optimum legibility in the dark. The calibre BR-CAL.323, chronometer-certified by the COSC, can be seen through the tinted crystal in the centre of the dial and the sapphire on the case-back. The 70-hour power reserve indicator, shaped like a fuel gauge, accentuates the sports styling of the BR-X5 Racing.
