The Breitling Navitimer B01 Chronograph 43 (Ref. RB0120121B1P1), launched in 2025, continues the legacy of one of the most iconic pilot’s watches in aviation history. Revered since its debut in 1952, the Navitimer remains a symbol of technical mastery and design precision — now presented in a refined 18K red gold case that underscores its timeless elegance. The case measures 43 mm in diameter and 14.22 mm in height, featuring a bidirectional ratcheted bezel with Breitling’s signature circular slide rule, allowing on-the-fly flight calculations. Both sides are protected by cambered sapphire crystals, glareproofed internally and externally, ensuring clarity in all lighting conditions. Water resistance is rated at 30 meters. The black dial contrasts beautifully with silver subdials arranged in the traditional 3-6-9 layout, displaying chronograph hours, minutes, and running seconds. Applied hour markers, a red central chronograph seconds hand, and a discreet date window between 4 and 5 o’clock complete the composition. At its heart beats the Breitling Calibre B01, an in-house automatic column-wheel chronograph with a vertical clutch for smooth precision. Operating at 28,800 vibrations per hour (4 Hz), it delivers a 70-hour power reserve and bears COSC chronometer certification. The Navitimer B01 Chronograph 43 RB0120121B1P1 is paired with a brown alligator leather strap and an 18K red gold tang buckle, combining aviation heritage with contemporary luxury.
