The Casio CA-506-1 is a steel calculator watch introduced in 1984, with a twenty-key membrane pad below the LCD on a folded-link bracelet. Module 437 provides an eight-digit four-function calculator, dual time, alarm and stopwatch, but no data-bank memory. (Digital-Watch.com; Casio Operation Guide 437/438/3208) Casio's CD-40, also dated to 1984, took the other branch by storing telephone numbers. (Casio Vintage Collection) CA-506-1DF is a regional suffix for the same product. (Casio)
