Product Specifications:
The Casio F-91W-1AEF is one of the most recognizable digital watches from the Casio Timeless Collection. Its all-black design with the classic square case and black resin strap gives the watch a simple, retro look that has remained virtually unchanged since the F-91W was introduced in 1989. Thanks to its light and compact design, this is a versatile unisex watch that is worn comfortably by both women and men.
Weighing only 21 grams, you will barely notice you are wearing the watch. The case measures 38.2 × 35.2 × 8.5 mm and the flexible resin strap is suitable for wrist circumferences of approximately 145 to 200 mm. The F-91W is water-resistant for daily use and has a battery life of approximately seven years on one CR2016 battery.
Despite its simple appearance, the F-91W offers several practical functions. The digital watch features a stopwatch that measures up to 1/100 of a second, a daily alarm, hourly time signal, automatic calendar, and LED lighting. The combination of the iconic design, light weight, and useful features makes the F-91W-1AEF a timeless Casio that can easily be worn every day.
