The "Montbrillant Datora" is a revival of Breitling's best-selling model from the 1940s. This chronograph, featuring a triple calendar, indicates the date with crescent-shaped pointer hands and includes small windows for the month and day at the 12 o'clock position. Its appeal lies in its classical yet mechanical face design.

While the standard Montbrillant is a compact 38mm chronograph, the Datora, equipped with a triple calendar, boasts a larger 43mm case, offering a distinct presence on the wrist. The dial is available in black, silver, and bronze as pictured, along with a two-tone bronze and silver option. The color of the indices also varies depending on the case material, allowing for a choice of designs from various configurations.

Like other models in the Navitimer line, it also features a rotating slide rule for aviation calculations. By manipulating the bezel, various calculations necessary for flight plans can be performed. A red-printed tachymeter is positioned in the center of the dial, which can be considered another vintage-like feature reminiscent of classic chronographs.
