. . . because my preference for chronograph design in general reflects an absence of calendar indicators. The purpose of a chrono is to measure a slice of time. When a calendar function is added, the watch then has two objectives, and they are diametrically opposed - one focuses on the measurement of a specific event, and the other reflects the passing of time. That's why many, if not most, chronos with calendar capabilities strike me as bipolar, for lack of a better term.
