Casio Edifice 38mm EFR-109D-1AER

Some sports cars are appreciated not only for their performance, but also for the timeless elegance and dynamic spirit they retain over the years. Inspired by that enduring charm, the EFR-109 captures these qualities in a simple three-hand design. The slim 38mm case slips perfectly under a shirt cuff, while the understated design pairs effortlessly with a wide range of styles, from elegant to casual. The box-shaped crystal, with its delicately curved lines, provides a distinctive depth effect reminiscent of a vintage watch. Whether you are behind the wheel or relaxing at a cafe on the weekend, the watch fits perfectly for any occasion. Thanks to its water resistance up to 10 bar, it is also perfect for worry-free daily use. Combining a timeless design with details that reflect a sporty spirit, the EFR-109 is designed for those who appreciate both.
