The community take
Owners widely praise the Breitling Premier B01 Chronograph 42 for its elegant, timeless design, exceptional finishing, and high-quality feel, with many noting it looks even better in person. Reviewers and owners alike highlight the versatile design, thoughtful proportions, and the in-house B01 movement as significant strengths, offering excellent value. Some owners find the chronograph pushers stiff to start or note the reset arm requires extra effort on the first press, and one owner reported accuracy of approximately five seconds fast per day. While some wished for a 40mm option, others found the 42mm case wears slimmer and closer to the wrist. The lume is considered lackluster by one owner due to small application areas, and some users advise caution regarding the price, suggesting consideration of used options or potential servicing and quality control concerns.
