Product Details
Description
The Casio EDIFICE EFS-S640PB-1AVUEF is a sporty solar chronograph for men that translates the world of motorsport into a precise watch case. The case made of carbon fibre-reinforced resin with an ion-plated stainless steel bezel is lightweight, robust, and visually inspired by the double-wishbone suspension of a Formula racing car. The diameter measures 44.5 mm with a thickness of 13.3 mm – compact enough for comfortable everyday wear on the wrist.
The carbon fibre dial makes a bold statement and reinforces the motorsport character of this watch. Behind the three integrated subdials, solar modules generate sufficient energy even in low light, allowing the model to operate for approximately five months on a full charge without further recharging. A scratch-resistant sapphire crystal with anti-reflective coating reliably protects the striking dial. The resin strap fits wrist circumferences from 14.5 to 21.5 cm, and the watch is water-resistant to 10 bar, making it ideal for sporting activities.
