The F-91W is the upgrade enthusiasts have always wanted. When the F-91W uses a standard LED microlight that only illuminates a portion of your display, the F-105W-1A steps up to a full electroluminescent backlight—the uniform glow technology found on more premium Casio models—illuminating soft, evenly distributed glow across the dial. There is a slight difference on paper and there is actually a huge difference. Especially in low-light environments where F-91W partial lighting leaves desirable. In watch collectors, the F-105W-1A developed a true supporter as the definitive edition of the classic Casio rectangular digital. Sometimes called "F91W EL". The reason is easy to understand. Everything else about the F-105W-1A is the same as the proven F-91W formula. Resin case measures 39 x 35.4 x 9.6 mm, total weight is only 21 grams. It is one of the most comfortable wearers that can be worn every day at any price because there is almost no presence on your wrist. The classic black case and blue accent ring and matching black resin band provide a timeless aesthetic that has made the F-Series an icon of design. Rectangular LCD dial includes time, day of the week and date, daily alarm, 1/100 second stopwatch, hourly time signal. Everything you need, everything you don't need and has been proven to be used daily for decades. One of the best casio's plain watches. Lightweight resin case, EL backlight, daily alarm, stopwatch, auto calendar with date. CR2016 battery lasts about 7 years and is waterproof to withstand daily use such as splashes of water, rain, etc. Whether you are a fan of upgrading the F-91W from the F-series, a first Casio buyer, or a collector who wants to add an EL variation to your lineup, the F-105W-1A is the definitive digital version of Casio desertcart.com Review Show off your classic style with the Casio Men's Illuminator Digital Watch #F105W-1A.
