Edifice Automatic EFK-100D-7A

The Casio Edifice EFK-100D-7A marks a significant step for the brand, introducing an automatic mechanical movement into its Edifice line. The watch features a solid stainless steel case measuring approximately 43.5 × 39 × 12.5 mm and weighs about 148 g. It houses a textured white dial — achieved via an electro-forming process to mimic the look of forged carbon — giving the piece a refined sporty aesthetic. The crystal is scratch-resistant sapphire, and the case back is transparent, allowing a view of the movement in action. The mechanical movement offers roughly a 40-hour power reserve, runs at 21,600 vibrations per hour, and uses 24 jewels. Accuracy is rated around –35 to +45 seconds per day. The watch is water-resistant up to 100 m (10 bar) and incorporates a robust stainless steel bracelet with a one-touch three-fold clasp. Additional features include a date display and a hacking seconds function.
