Breitling Montbrillant Datora Watch


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.



Montbrillant Datora timepiece runs on a self-winding Breitling B 21 mechanical movement and it includes a chrono feature with the accuracy of 1/5th of a second. The high-frequency caliber (28,800 v.p.h.) integrates 25 jewels and is made with a power reserve that lasts for at least 42 hours. Its automatic movement is fitted in a round case, made either form a stainless steel or 18K red gold. The case with a screwed in back is 43 mm wide and 14.1 mm thick. Without the strap, this timepiece weights 86.3 g (approximately 3 oz.). As it is quite expected for a product by the famous Swiss watch manufacturer, its face is safeguarded by a cambered sapphire glass with double glare-proof treatment.
