Casio EDIFICE Bluetooth Watch ECB-30DC-1AEF

Presenting the Casio EDIFICE ECB-30DC-1AEF, a large-format ana-digi chronograph that pushes motorsport-inspired design to its darkest extreme. The 48.7 mm stainless steel case with matte black IP treatment features a crown at 3 o'clock flanked by two pushers and a light button, all integrated into an architecturally bold case profile. The fully black dial organises three distinct layers of information: at the top near 12, a compact digital display shows local time with an active Bluetooth indicator; at 9, a rectangular digital window handles the alarm function; and at the lower section, a large analog subdial serves as the chronograph counter with an outer scale reaching 120 intervals, with orange accent details that cut through the dominant black. Hour markers are rectangular bar indices in silver-grey distributed across the rehaut, and the main hands are leaf-shaped with white luminescent treatment. The outer bezel carries tachymeter scale markings along with MODE at 8 and START at 4. The black IP stainless steel link bracelet completes a deliberate and coherent all-black aesthetic.

Inside runs the Casio module 5686, an ana-digi calibre built for the connected EDIFICE line. Bluetooth connectivity allows pairing with the CASIO WATCHES smartphone app for automatic time adjustment and alarm management. The analog chronograph measures up to 60 minutes via the lower subdial, while the digital displays handle a second time zone (local time), programmable alarm, automatic calendar, and world time. The lower bezel also labels the WT (world time) and AL (alarm) functions alongside the chronograph OVER indicator. Water resistance is rated at 10 bar (100 metres), suitable for swimming and non-professional water sports. A CR2016 battery powers the entire system.

EDIFICE is Casio's high-performance sports watch line, inspired by the technology and speed of motorsport. Since its launch, EDIFICE has equipped drivers and enthusiasts who demand real functionality in a design that echoes cockpit instrumentation. The ECB series integrates Bluetooth as standard, elevating the precision of the whole package through real-time synchronisation with global time networks.
