Undoubtedly, aviation and diving models hold a central place in Breitling's history and portfolio. Alongside its most popular series, however, the brand has also created a number of lesser-known timepieces that are in no way inferior to their more recognizable counterparts.

Today's model is a representative of just such a series — the Breitling Hercules.

Its name was by no means chosen by chance. Inspired by the mythological hero Hercules, upon its introduction in 2001, the watch was one of the largest automatic chronographs ever created by Breitling up to that point. The case has an impressive diameter of 44.8 mm and a thickness of 15.7 mm — dimensions that still guarantee a serious presence on the wrist today.

The overall feel is that of a true "instrument for professionals." The massive steel case, multiple functions, and bold proportions are combined with a surprisingly uncluttered and easy-to-read dial.

The details, finishing, and overall feel are at the high level characteristic of Breitling. The watch is impressive, eye-catching, and sits particularly well on a larger wrist. Despite its considerable size, the integrated design of the case and bracelet gives it a complete and relatively balanced silhouette.

The piece presented features the rarer and, in our opinion, particularly beautiful blue dial, combined with contrasting white counters and elongated applied hour markers.

The hands and the luminescent dots at the hour indices are coated with a generous layer of luminous material, ensuring good legibility in low light conditions. The contrast between the deep blue, the white counters, and the polished steel elements gives the watch a simultaneously sporty and elegant look.

One of the most characteristic parts of the Hercules is its bi-directionally rotating bezel. It features a degree scale and the letters N, E, S, and W, denoting the four cardinal directions.

The bezel does not turn the watch into a standalone compass, but it can be used as an orientation aid if information about the Sun's position is available. Above all, however, it is a strong design element that emphasizes the model's aviation and tool-watch character.

The crown is another accent that we particularly like in this series. It is massive, deeply knurled, and adorned with a large embossed "B". Its shape allows for easy operation even with gloves, and the guards on either side of it and the large chronograph pushers complete the watch's assertive look.

The Hercules impresses not only with its size but also with the unusual way it displays elapsed time.

Instead of the traditional small 30-minute counter, the model uses a central hand, which can easily read up to 60 chronograph minutes. This provides significantly better legibility when measuring intervals of up to one hour.

For longer periods, a combined counter with two hands is located at 6 o'clock, which displays the elapsed hours and minutes in a manner resembling a regular watch dial. At 9 o'clock is a 24-hour indicator, and the small seconds hand is located at 3 o'clock.

An IFR/VFR aviation indication has also been added to the periphery of the dial — another detail that connects the model to Breitling's long history of producing professional pilot's instruments.

At the heart of the watch beats the automatic Breitling Calibre 39. This is a modular chronograph movement, built on the proven ETA 2892-A2 base and supplemented with a specialized chronograph module.

The movement operates at a frequency of 28,800 vibrations per hour, has 38 jewels, and offers a power reserve of approximately 42 hours. In addition to the unusual reading of chronograph minutes and hours, it also provides the 24-hour indication on the dial.

The Calibre 39 is officially certified as a chronometer by COSC. This means that the movement has passed independent tests for accuracy in various positions and at different temperatures.

The modular construction is more complex to service than a standard integrated chronograph, but the ETA 2892-A2 base is widely known to watchmakers and has proven itself as a reliable and high-quality platform. With proper maintenance, the movement is perfectly suitable for regular daily wear.

The case is equipped with a screw-down crown and case back, and the sapphire crystal has an anti-reflective coating on both sides. The official water resistance is 100 meters — perfectly sufficient for everyday use and swimming, provided that the crown is properly screwed down and the gaskets are in good condition.

The massive integrated steel bracelet is an essential part of the overall design. It continues the lines of the case, distributes the considerable weight of the watch well, and leaves no doubt as to which model you are wearing on your wrist.

The Breitling Hercules is not a watch that tries to be discreet. It is large, heavy, functional, and unmistakably recognizable — a product of an era in which Breitling created some of its boldest professional models.

It is enough to hold it in your hand or simply gaze at the unusual dial, the massive bezel, and the complex chronograph system to understand why the brand used its iconic slogan for so long: "Instruments for Professionals."
