Product details
The Casio F-105W-1A occupies a unique and beloved position in the Casio digital lineup — it's the F-91W with the one upgrade that enthusiasts have always wanted. Where the F-91W uses a standard LED micro-light that illuminates only a portion of the display, the F-105W-1A steps up to a full Electro Luminescent backlight — the same even-glow technology found in more premium Casio models — that lights the entire dial surface in one soft, evenly distributed glow. It's a small difference on paper and a significant one in practice, especially in low-light environments where the F-91W's partial illumination leaves something to be desired. In watch collector circles, the F-105W-1A has developed a genuine following as the definitive version of the classic Casio rectangular digital — often called the ""F91W EL"" — and it's easy to understand why. Everything else about the F-105W-1A is unchanged from the proven F-91W formula. The resin case measures 39 × 35.4 × 9.6mm and the total weight is just 21 grams — a barely-there presence on the wrist that makes it one of the most comfortable daily wearers available at any price. The classic black case with blue accent ring and matching black resin band deliver the timeless aesthetic that has made the F-series a design icon. The rectangular LCD dial displays time, day, and date, and includes a daily alarm, 1/100-second stopwatch, and hourly time signal — everything you need, nothing you don't, in a layout that has proven itself across decades of daily use. CASIO This is one of Casio's best no-frills watches — a lightweight resin case, EL backlight, daily alarm, stopwatch, and an auto-calendar that handles the date so you don't have to. A CR2016 battery powers it for approximately 7 years, and the watch is water resistant for everyday use including splashes and rain. Whether you're a long-time F-series fan upgrading from the F-91W, a first-time Casio buyer, or a collector looking to add the EL variant to the lineup — the F-105W-1A is the definitive everyday Casio digital.
