The Breitling Premier B01 Chronograph 42 (Ref. RB0145171C1P1) was introduced in 2025 as part of a capsule collection that combines timeless elegance with modern proportions. Reflecting Breitling’s heritage of refined chronographs, this model unites classic design elements with advanced in-house mechanics. The 42 mm case is crafted from 18K red gold, measuring 13.6 mm thick, and features a cambered sapphire crystal with anti-reflective coating on both sides. A sapphire display back offers a clear view of the movement, while the fixed bezel and 100-meter (10 bar) water resistance provide both functionality and luxury. The blue dial features applied Arabic numerals, recessed subdials for running seconds and a 30-minute chronograph counter, and gold-tone leaf hands. The clean bi-compax layout maintains the Premier collection’s signature balance and readability, delivering understated sophistication suitable for any occasion. Powering the watch is the Breitling Caliber B01, an in-house automatic chronograph movement with a column wheel and vertical clutch for precise operation. Running at 28,800 vibrations per hour (4 Hz), it provides a 70-hour power reserve and superior accuracy. The Premier B01 Chronograph 42 RB0145171C1P1 is fitted with a gold-brown alligator leather strap secured by an 18K red gold folding clasp, representing a perfect harmony of craftsmanship, performance, and style.
