When a watchmaker has a proud tradition and a rich history, it is not surprising that it has a tendency to draw the inspiration from the previous successful models. This is exactly the case with Breitling’s timepiece Montbrillant Datora which was a very sought-after model and one of the bestselling watches made by the Swiss company during the 1940s. Montbrillant Datora demonstrates the mechanical expertise of the manufacturer. It is a chronograph that offers a host of information on its dial. One of the most notable features is the inclusion of a full calendar with month and day apertures placed next to each other, supplemented with a hand which circles around the dial and indicates current date. Other notable features are the presence of the aviation slide-rule bezel and alternative hour displays.

As it has been explained, the face of the watch includes a lot of information and might seem a bit too overcrowded, depending on the taste. The watch has a bidirectional rotating slide rule bezel, convenient for aviators. Apart from this scale, the flange of the dial includes 24-hour scale that displays the time in a military manner, and there is also a scale that shows the date (indicated by a central pointer that ends with a half-moon. Its dial includes three subsidiary dials, and the one placed at the top (30-minute chrono counter) has day and month apertures inside it which gives this watch an original and unusual appearance. The dial with luminous hour and minute hands and a sweeping seconds hand is rounded with a 1/100th of an hour display at the center that overlaps with its sub-dial. All in all, even though there are a lot of functions and indications, this chronograph has an overall vintage look of the aviator’s instrument that makes it appealing, despite the multitude of information on it.
