Breitling Navitimer 01 43 Red Gold / Black / Alligator Ref. RB0120121B1P1

The Breitling Navitimer B01 Chronograph 43 RB0120121B1P1 debuted in 2025 as part of the brand’s core Navitimer collection, continuing the lineage of one of the most recognizable pilot’s chronographs ever produced. The case is crafted in 18k red gold, measuring 43 mm in diameter and 14.22 mm in height, with a bidirectional ratcheted bezel incorporating the signature circular slide rule for airborne calculations. The watch is fitted with cambered sapphire crystals on both sides, glareproofed internally and externally. Water resistance is rated at 30 meters. The black dial features silver subdials arranged in the classic 3-6-9 layout for elapsed hours, minutes, and running seconds, complemented by applied hour markers and a red central chronograph seconds hand. A date aperture is positioned discreetly between 4 and 5 o’clock. Inside ticks the automatic Caliber B01, Breitling’s in-house column-wheel chronograph movement. Operating at 28,800 vibrations per hour (4 Hz), it offers a 70-hour power reserve and features a vertical clutch for precise start-stop operation. The movement is visible through a sapphire crystal case back and bears COSC chronometer certification. The Navitimer B01 Chronograph 43 RB0120121B1P1 is fitted with a brown alligator leather strap secured by an 18k red gold tang buckle.
