The Casio F91W-1 wristwatch for men has been a popular digital model since its release in the early 1990s. The black resin band looks good with most daytime wear, and the digital accessories are useful and convenient. Made with study materials and using reliable quartz movement, this watch is perfect for men or women who value function and efficiency. This sporty chronograph watch features a 1/100 digital stopwatch that runs up to just shy of an hour. It is useful for athletes in training, coaches, and referees. These watches also have multiple measuring modes, allowing you to keep track of split, net, and both first and second place times. An hourly time signal can help watch wearers increase their productivity on and off the job, keeping them focused and on task. The automatic perpetual calendar never needs setting and keeps you informed of the date at a glance. Found at the top of the display, the day is written in English and the date is in Arabic numerals. An intuitive design makes these watches easy to set and easy to use for men of any age.
