Housed in a 46mm 18K rose gold case, this Navitimer B01 Chronograph presents a silver dial adorned with applied rose gold-tone index hour markers featuring luminous tips, rose gold-tone hands with luminous fill, and a fine printed minutes, seconds, and fraction-of-a-second track. A small running seconds sub-dial sits at 9 o'clock, a date window falls between 4 and 5 o'clock, and the chronograph architecture includes a large central red seconds hand, a 30-minute counter at 3 o'clock, and a 12-hour counter at 6 o'clock. The cambered sapphire crystal is glare-proofed on both sides, and a transparent case back reveals the movement within.
The iconic slide-rule bidirectional rotating bezel — Breitling's navigation-computer complication — enables airborne calculations including fuel consumption, climbing times, and conversion between miles, nautical miles, and kilometers. Power comes from the automatic Breitling caliber B01, which carries 47 jewels and offers an approximate 70-hour power reserve. The 18K rose gold crown is non-screw-locked and fitted with two gaskets, and water resistance is rated to 30m / 99ft.
The watch is presented on a brown alligator leather strap with white stitching, secured by an 18K rose gold tang buckle clasp. Reference RB0127121G1P2 is supplied complete with the original Breitling watch box and Breitling papers.
