Speed & Intelligence at your fingertips. The EDIFICE EFS-S660 captures the exhilaration of driving in a design that is all about simple, no-fuss functional beauty.
This analog timepiece packs all the tracking functions you need into a slim, compact case measuring just 38.3 mm. The center chronograph seconds hand delivers a high-precision 1/20 second stopwatch, while the tachymeter around the periphery of the bezel helps you calculate your average speed. The dial is treated to a sophisticated textural finish, yet still lets enough light through to generate the solar power to keep you going strong.
Designed with readability in mind, the center seconds hand ensures you know the time at a glance, delivering the practical utility every motorsport enthusiast wants. With sapphire crystal, 100-meter water resistance, and solar power charging, this watch delivers reliable support, no matter what your day brings.
Choose your favorite style — The sharp, fearless EFS-S660D-1A with stainless-steel case and band and blue center seconds hand, or the sporty EFS-S660PB-1A with gray ion-plated case, resin band and red center seconds hand.Basic Information
