EFS-S640ZE-1AER

PRE-PURCHASE AVAILABLE

The EFS-S640ZE embodies the spirit of craftsmanship in this special edition.

This solar-powered EDIFICE chronograph features a black and gold color scheme that evokes the first flash of light, that spark of innovative craftsmanship, where the creation of new value begins.

The golden loop on the strap, with the laser-engraved inscription “”50TH ANNIVERSARY“”, flickers on the black strap like a light that breaks through the darkness and illuminates the path to value innovation.

As a special design touch, the dial inset at the 9 o'clock position is printed with 0 and 1, capturing Casio's devotion to the art of making something out of nothing. 

Based on the solar-powered SOSPENSIOE EFS-S640, the carbon fiber reinforced resin watch case features a unique design inspired by the suspension of a formula car with lugs configured in a four-arm arrangement. Together with the carbon fiber dial, this watch radiates an authentic automotive spirit. The band is made of Alcantara, a highly durable and breathable material used in the interior of sports cars. With its international carbon neutrality certification, the fabric is also expected to contribute to reducing environmental impact.
