Breitling Premier Heritage B21 Chronograph Tourbillon North America Ref. RB21204A1C1P1

The Breitling Premier B21 Chronograph Tourbillon 42 Limited Edition RB21204A1C1P1 debuted in 2025 as a North America–exclusive edition limited to 75 pieces. The watch combines an 18K red gold case with a blue gradient dial and integrates a one-minute tourbillon with a chronograph function — a configuration that underscores Breitling’s technical collaboration with La Joux-Perret. The case measures 42 mm in diameter and 15.25 mm in height, with rectangular pushers, a domed sapphire crystal, and a sapphire case back providing a view of the movement. Water resistance is rated at 100 meters. The blue gradient dial features applied Arabic numerals, gold hands, and a 60-minute counter at 6 o’clock. The tourbillon is positioned at 12 o’clock beneath a curved bridge, forming the visual and mechanical focus of the composition. This model is powered by the self-winding Caliber B21, a column-wheel chronograph tourbillon movement operating at 28,800 vibrations per hour with a power reserve of approximately 55 hours. It is equipped with a gold oscillating weight visible beneath the domed sapphire case back. The Premier B21 Chronograph Tourbillon 42 Limited Edition RB21204A1C1P1 is fitted with a brown alligator leather strap secured by an 18 K red gold folding clasp.
