The Breitling Chronomat Evolution Two-Tone (Ref. B13356-086) is a men’s automatic chronograph produced between 2005 and 2007, belonging to a particularly recognizable period of Breitling sports watch production. Positioned within the luxury Swiss watch segment, it combines the robust character of the Chronomat family with a decidedly more striking two-tone configuration than the all-steel versions.
Its personality comes from the meeting of two seemingly contrasting elements: the functional approach of a sports chronograph and an aesthetic in which yellow gold plays a prominent role. It is therefore not a model designed for discretion, but rather a timepiece aimed at those who appreciate the strong visual presence of Breitling watches from that period without sacrificing genuinely usable technical features. The blue dial with gold-toned counters represents the defining feature of the configuration shown, creating an immediately recognizable contrast.
Design
The blue dial is the watch’s primary chromatic element. Its intense surface provides the backdrop for the three light-colored counters arranged according to the movement’s characteristic vertical architecture, while the gold-toned elements introduce a strong contrast that gives the chronograph a more elaborate appearance than the monochromatic configurations within the same family.
The applied hour markers and hands retain a robust and easily recognizable construction, consistent with the model’s sporting character. The peripheral minute track is particularly dense and contributes to giving the dial the instrument-like appearance typical of Breitling production from that era. The tachymeter scale also appears around the outer edge, integrated without disrupting the visual continuity of the composition.
The three counters are clearly separated from the background by their contrasting color and create strong symmetry along the vertical axis. The date display at 3 o’clock, meanwhile, occupies its own distinct space, fitting among the dial elements without excessively disturbing the overall balance. The amount of information is considerable, but the visual hierarchy remains sufficiently clear thanks to the contrast between blue, gold, and light-colored details.
The gold-toned rider tabs on the bezel also play an important role, extending the two-tone theme from the dial to the exterior of the watch. The crown and pushers follow the same visual language, making the steel-and-gold combination part of the overall architecture rather than merely a decorative detail.
In the configuration shown, the dark blue leather strap partially tones down the visual impact of the gold and creates continuity with the dial. Compared with a two-tone Pilot bracelet, this solution focuses more attention on the watch head and makes the chromatic contrast less dominant across the wrist.
Case & Construction
The case combines stainless steel with elements in 18K yellow gold, with alternating surfaces that emphasize the substantial construction of the Chronomat Evolution. Its 43.7 mm diameter is accompanied by a thickness of 17.1 mm, 22 mm lugs, and a lug-to-lug measurement of approximately 52 mm: proportions that clearly place the model among the large sports chronographs of its era.
The unidirectional rotating bezel is one of the construction’s most characteristic functional elements. The four protruding rider tabs make it easier to operate while also helping to protect the bezel surface. On this version, they also become an important aesthetic element thanks to their gold-toned finish.
On the right side, the crown and chronograph pushers occupy considerable space and reinforce the technical appearance of the case. Their integration is consistent with a design in which robustness and ease of operation take precedence over the pursuit of a slim silhouette.
The crystal is sapphire with an anti-reflective treatment, an appropriate choice considering the amount of information displayed on the dial and the need to preserve its legibility. Water resistance reaches 300 meters (30 ATM), a particularly high rating for a luxury automatic chronograph and one of the features that genuinely distinguishes this model from many contemporary sports chronographs less focused on robustness.
Movement
Inside is the Breitling Caliber 13, an automatic movement derived from the Valjoux 7750 and COSC chronometer-certified. It is a choice consistent with the philosophy of the model: a proven mechanism focused on reliability, rather than a caliber developed in pursuit of thinness or particular architectural refinement.
The power reserve is approximately 42 hours. The movement natively manages the time display, small seconds, date, and chronograph, providing all the required functional architecture without relying on a construction primarily intended for decorative purposes.
One of the practical advantages of this mechanical base is its widespread use throughout the watch industry. For an example that now belongs to the pre-owned market, the familiarity of specialist watchmakers with the 7750 family represents a favorable factor from a servicing perspective. At the same time, its construction contributes to the watch’s substantial thickness: an evident structural compromise, but one that remains consistent with the robust character of the overall design.
The COSC certification also adds an objective performance benchmark to the timepiece and distinguishes the Caliber 13 used in this application from a standard implementation of the underlying mechanical platform.
Functions & Complications
Interaction with the chronograph follows a particularly intuitive layout: the 30-minute counter occupies the upper position, the 12-hour counter the lower one, while the small seconds are positioned laterally. This arrangement keeps the reading of continuous time separate from that of elapsed time.
The prominent pushers provide decisive operation, while the contrast between the counters and the dial makes the supplementary indications easy to identify. The date display at 3 o’clock remains sufficiently isolated from the counter layout and can be read without becoming confused with the chronograph information. The crown handles the adjustment of hours, minutes, and date, keeping the everyday management of these indications straightforward and conventional.
The tachymeter scale broadens the chronograph’s range of uses and reinforces the instrument-like character of the dial. The unidirectional rotating bezel, meanwhile, provides a second method of measuring elapsed time independently of the chronograph mechanism, useful when there is no need to operate the pushers.
The result is a functionally rich yet still immediate and entirely analog arrangement: the wearer has access to multiple indications without the model resorting to additional displays or complications unrelated to its sporting identity.
Performance
On the wrist, the Chronomat Evolution has a substantial presence. The case sits high and occupies a considerable portion of the wrist, while the architecture of the lugs distributes the watch head more effectively across medium-to-large wrists. This is not a chronograph that disappears beneath clothing, and its character remains immediately apparent even with casual attire.
The concentration of metal in the case, bezel, and side controls makes the watch head visually and physically substantial. The leather strap of the configuration shown gradually conforms to the wrist and keeps the overall weight lower than an all-metal configuration, while leaving the sense of solidity of the central watch head unchanged.
Under a close-fitting cuff, the thickness is clearly noticeable and makes the model less suitable for traditional formal wear. With less structured jackets, casual clothing, or sportswear, however, its proportions find a more natural context.
The ergonomics of the controls follow the same approach. Crown, pushers, and rider tabs are easy to reach and prioritize grip over discretion. Overall, the fit rewards those deliberately seeking a pronounced wrist presence, while proving less convincing for anyone who prefers thin, lightweight, or visually restrained chronographs.

The Breitling Chronomat Evolution Two-Tone effectively represents a concept of the luxury sports chronograph in which robustness, proven mechanics, and strong visual identity coexist within the same design. The combination of the blue dial and gold-toned elements gives it a very specific personality and makes it noticeably different from the more conservative all-steel configurations.
Its principal strengths include particularly robust construction, high water resistance, a COSC-certified movement, and a comprehensive chronograph configuration. The caliber’s Valjoux origins also have pragmatic value today: it does not offer the exclusivity of a manufacture movement, but prioritizes a familiar and well-established platform, an aspect that is far from insignificant for a watch of this age.
Its limitations are equally tangible. The case is large and thick, making it less suitable if you are looking for versatility with formal clothing. The two-tone aesthetic is also deliberately assertive and reflects the stylistic codes of its production period more strongly than other configurations. Finally, the Caliber 13 lacks the degree of mechanical exclusivity that some buyers now expect from a luxury Swiss chronograph.
Its original retail price of approximately 4,600 euros, equivalent at the time to around 5,400 dollars, clearly positioned it within the premium segment of Breitling sports watch production. Its value, however, is best assessed within today’s pre-owned market, where case condition, service history, originality of components, and the presence of the original accessories and documentation can significantly influence the appeal of an individual example.
The verdict is positive if you are looking for a Breitling that is strongly representative of the 2000s, with genuine sports chronograph credentials and an immediately recognizable aesthetic. It is less suitable if you prioritize thinness, discretion, or caliber exclusivity. Yet this very lack of neutrality forms part of its appeal: the Chronomat Evolution Two-Tone does not attempt to be universal, but instead confidently expresses the technical and stylistic identity of its generation.
