An elite unit of the French Air and Space Force, the Patrouille de France has established itself for 70 years as one of the most prominent aerobatic display teams. If the BR 03-92 PATROUILLE DE FRANCE 70TH ANNIVERSARY is intended to celebrate the anniversary of the Patrouille de France, it is nonetheless a professional instrument. As proof, it adopts the fuselage of the BR 03, that is to say an ultra-light square-shaped case (42 x 42 mm) in high-tech ceramic, treated here with a black coating accentuating the contrasts. Both technical and contemporary, water-resistant to 100 metres, it protects the automatic mechanical movement calibre, BR-CAL 302, which indicates the hours, minutes, seconds and date. For the dial of this exclusive anniversary limited edition of 999 pieces, Bell & Ross has chosen a particularly luminous shade of blue, evoking the colour of the Alpha Jet of the Patrouille de France.
