avi-8 av-4077-01 The avi-8 men's watch av-4077-01 is an accessory for aviation-enthusiast watch fans from the P-51 Mustang Chronograph 43mm model series. It's the perfect choice if you're looking for a timepiece with an aviation and pilot-inspired look. The chronograph function makes this watch a prized accessory for athletes and anyone who needs a timing tool to keep track of personal bests, running times, preparation times, or similar metrics. The watch features a silver case made of stainless steel, which stands out as a real eye-catcher thanks to its matte and polished finish. The round case is 43 mm wide and 13 mm high and, depending on individual taste, of course, complements nearly any wrist. The fixed bezel stands out subtly from the case. The watch’s case back is a screw-down stainless steel back that rounds out the attractive design. The “tempered mineral glass” watch crystal offers extensive protection against accidental scratches and damage. Beneath it, the dial of your new dream watch is silver in color. Luminous hands illuminate the avi-8 av-4077-01, ensuring excellent readability even in low-light conditions. At the heart of this timepiece is a quartz movement (battery-powered) which, as is standard for avi-8 watches, guarantees precise timekeeping and offers the following functions: 24-hour display, chronograph, date, minute, second, hour. Its water resistance of 5 atm (test pressure) ensures it’s well-suited for everyday use, as shown in the list below: 3 atm: Water splashes while washing your hands are fine. 5 atm: You can shower and bathe with this watch. Swimming or diving is not recommended. 10 atm: The watch can handle a trip to the pool, but not diving. 20 atm and above: At 20 atm and above, the watch is considered water-resistant and suitable for swimming and shallow-water diving*. You’ll enjoy your new avi-8 watch even more thanks to the high-quality calfskin leather strap—color: black—with a pin buckle. The calfskin leather strap offers exceptional comfort and can be worn on wrists up to 230 mm in circumference. *Water resistance is not a permanent feature and must be checked regularly and professionally when the watch is used as intended. For watches with screw-down pushers and/or a screw-down crown, ensure that these are securely tightened by hand so that the watch can be water-resistant at all.
