What to know
The EFK-100CD-1A belongs to the first generation of Casio Edifice mechanical automatics. Forged carbon, a material strongly linked to motorsport and aerospace, gives the black dial an irregular, individual appearance. It pairs that unusual surface with the geometry of a classic steel sports watch.
This 39 mm automatic is driven by a Japanese mechanical movement with manual winding and a quoted 40-hour reserve. The case is 12.5 mm thick, with sapphire crystal, an exhibition back and 100-metre water resistance. It is part of the 2025 launch family, included here to give the newer EFK-110 and EFK-200 models their proper historical context.
