The Breitling Avenger Chronograph 45 Ref. A13317101B1A1 is a bold and shock-resistant instrument watch, engineered for the skies with a commanding presence and uncompromising precision . This robust timepiece features a 45mm stainless steel case with a unidirectional ratcheted rotating bezel and a distinctive grip pattern on the crown and pushers, ensuring easy operation even while wearing gloves—a hallmark of the Avenger’s aviation-focused design . The matte black dial serves as a highly legible canvas, featuring silver-toned hands and applied stick indexes, both coated with luminescent material for optimal readability in all conditions . The chronograph function is displayed through three sub-dials, with a 30-minute counter at 12 o’clock, a 12-hour counter at 6 o’clock, and a small seconds sub-dial at 9 o’clock, complemented by a practical date window at 3 o’clock . At its heart beats the Breitling Caliber 13, a COSC-certified chronometer, a self-winding automatic movement that delivers a 48-hour power reserve and operates at a frequency of 28,800 vph . Visible through the cambered, glareproofed sapphire crystal, this movement ensures the watch’s reliability and precision are certified to the highest standards . Completed with a robust stainless steel bracelet and a screw-down caseback, this timepiece is water-resistant to an exceptional 300 meters (1,000 feet) . For the discerning collector who demands a watch that is as functional as it is formidable, the Avenger Chronograph 45 is a quintessential tool watch that excels in any demanding environment, offering the perfect synthesis of Breitling’s aviation heritage, technical sophistication, and enduring style
