A favorite for decades — the slim, lightweight F-91 with digital LCD now with a minimalist face, fewer mode indicators, and more environmentally responsible materials.

The band is made with bio-based resin, a material expected to help reduce environmental impact. Complete with date/day display, alarm, stopwatch and other handy functions, these watches are always at the ready.
