Edifice built its identity on motorsport from the start, and Casio's Red Bull Racing partnership — running since 2009 — is the clearest expression of that. The relationship produced a string of limited-edition watches over the following decade, and even after Red Bull's senior F1 team moved to a different watch partner in 2016, Casio stayed in the paddock by shifting its sponsorship to Red Bull's sister team, keeping the Edifice name on race suits through the 2022 season.
The EQB-900DB-2AJF carries that DNA into a daily-wearable form: a Bluetooth Smart connection to Casio's companion app keeps the time accurate automatically, a dual-dial layout displays two of roughly 300 world cities at once, and Tough Solar charging means it never needs a battery swap. Casio calls it the smallest case in the EQB series to date — motorsport styling scaled down for everyday wear.
