Casio EF527D-1AV Edifice Watches

Comfort, style and intelligence all come together in the Edifice EF527D-1AV. Smaller rounded band segments allow its solid stainless steel band to hug the wrist with more comfort while a knurled bezel, precision dial indexes and mineral glass give the timepiece a stylish, technical look. Inside, a 1/20th Chronograph and rotating Slide Rule allow for precision measurement and calculations such as time, speed, fuel consumption and more.
