Design and Aesthetics:
The UB012721 Breitling Navitimer 01 46mm boasts a commanding presence on the wrist. Its 46mm case, a significant size for some, is expertly crafted from a combination of stainless steel and rose gold. This two-tone approach adds a touch of sophistication and luxury, differentiating it from the purely stainless steel versions. The rose gold accents, typically found on the bezel and possibly the crown and pushers depending on the specific sub-model, create an elegant contrast against the brushed stainless steel. The dial, often described as black (although variations exist), features the characteristic Navitimer layout: the iconic slide rule bezel, three sub-dials for chronograph functions (hours, minutes, and seconds), and highly legible Arabic numerals. The use of Super-LumiNova on the hands and markers ensures excellent readability in low-light conditions, a crucial feature for a watch with aviation heritage. The watch face itself is typically protected by a sapphire crystal, known for its scratch resistance. The overall aesthetic is one of robust elegance – a perfect blend of classic design and modern refinement. The combination of stainless steel and rose gold is a tasteful choice, avoiding the ostentatiousness that can sometimes accompany all-gold watches while still conveying a sense of luxury and prestige.
Movement and Functionality:
The heart of the UB012721 is the Breitling Caliber 01, an in-house manufactured automatic chronograph movement. This is a significant point of distinction, as it signifies Breitling's commitment to vertical integration and high-quality movement production. The Caliber 01 is known for its reliability, precision, and impressive power reserve (typically around 70 hours). The chronograph function operates smoothly, with precise start, stop, and reset actions. The slide rule bezel, a defining feature of the Navitimer, allows for quick calculations related to flight, such as speed, distance, fuel consumption, and time conversion. While its practical use might be limited in the modern age of readily available digital calculators and flight computers, it remains a powerful symbol of the watch's history and heritage, appealing to both aviation enthusiasts and watch aficionados. The date window, usually located at 3 o'clock, adds a practical element without disrupting the overall aesthetic balance.
