The Jacob & Co. Epic X Black Titanium (Ref. EX110.21.AA.AF.A) is a contemporary hand-wound mechanical watch, produced from the 2020s onward and positioned in the luxury segment. Part of the Epic X collection, it interprets the sports watch concept through a skeleton construction in which the movement is not simply displayed, but becomes an integral part of the model’s identity.
Its defining characteristic is precisely the integration between exposed mechanics and design. The internal architecture determines much of the frontal composition, while the dark exterior and chromatic details accentuate the contemporary character of the whole. It is therefore aimed primarily at enthusiasts who consider observing the movement and strong wrist presence central elements when choosing a luxury watch.
Design
The absence of a traditional dial allows the mechanics to shape much of the composition. Bridges, gear trains, and moving components remain exposed, organized around a strongly vertical layout that brings order to an otherwise highly complex surface.
Black dominates the outer frame, rehaut, and several structural elements, creating a visually defined backdrop for the metallic and warmer tones of the mechanics. On the right side, the Jacob & Co. signature in red introduces an immediately recognizable chromatic accent and decisively breaks up the predominance of darker tones.
The hands are broad and partially skeletonized, with light-colored inserts and small red details that separate them from the mechanical texture beneath. The black peripheral minute track with light-colored markings frames the composition and provides a conventional reference for reading the time.
The Honeycomb rubber strap also plays an active role in the design. Its perforated hexagonal-cell structure echoes the technical language of the watch and visually breaks up the continuity of the black surfaces. Rather than attempting to make the timepiece appear classical, the combination reinforces its sporty and contemporary character.
Case & Construction
The case is made of black DLC-coated Grade 5 titanium. The surface treatment creates continuity between the different structural elements and contributes to the technical character of the construction.
The architecture departs from the configuration of a traditional round case with simple attached lugs. The upper and lower extremities are integrated into the central body through pronounced profiles and faceted surfaces, while the lateral protections help define a complex and immediately recognizable structure.
The diameter is 44 mm, the thickness is 13.05 mm, the lug-to-lug distance is estimated at approximately 51.5 mm, and the space between the lugs at around 22 mm. The proportions therefore confirm a substantial frontal presence, accompanied by a relatively controlled profile compared with the overall width of the case.
At the front, the watch uses an anti-reflective sapphire crystal, a solution particularly suited to keeping the different levels of the movement clearly visible. The caseback also uses transparent sapphire crystal, extending the view of the mechanical construction to the rear.
The stated water resistance for this configuration is 100 meters, equivalent to 10 ATM. This is an appropriate rating for everyday use and provides greater peace of mind around water, without giving the model the specialist credentials of a diver or a watch specifically designed for underwater activities.
Movement
At the heart of the watch is the Jacob & Co. JCAM02, a Swiss Made hand-wound mechanical caliber developed to integrate with the collection’s skeletonized architecture. The barrel and balance wheel occupy immediately recognizable positions along the vertical axis, making the organization of the mechanical components a direct part of the design.
The movement operates at 28,800 vibrations per hour, equivalent to 4 Hz, uses 21 jewels, and consists of 158 components. The power reserve reaches approximately 48 hours. The absence of a rotor also leaves the rear view of the caliber unobstructed and preserves the central role assigned to its architecture.
Manual operation requires periodic interaction with the crown, creating a more direct relationship with the mechanics than an automatic solution. In this case, it is not merely a technical choice, but one that is consistent with a watch built around the idea of keeping the movement constantly in the spotlight.
The verified data does not provide sufficient evidence to attribute specific certified chronometric performance, a hacking-seconds function, or particular service intervals to the JCAM02; these aspects should therefore not be considered confirmed features of the model.
Functions & Complications
From a functional standpoint, the timepiece adopts an essential configuration limited to the indication of hours and minutes. Adjustment is performed through the crown, with no additional indications to manage.
The skeletonization represents the main technical and visual characteristic, but it is not a horological complication in the strict sense. The presence of the mechanical components on the same visual plane as the hands makes reading the time less immediate than on a solid dial, while the peripheral minute track maintains a sufficiently well-defined reference.
Performance
On the wrist, the case sits with a pronounced presence. The broad frontal surface, sculpted lugs, and open construction give the timepiece considerable visual impact, while the profile prevents the overall form from becoming equally dominant in height. The geometry particularly favors medium to large wrists and deliberately preserves the distinctive character of the collection.
The titanium reduces the sense of mass suggested by the shapes at first glance and contributes to more favorable balance during extended wear. The rubber strap conforms to the wrist and provides support consistent with a broad, structured case, without introducing the rigidity of a metal bracelet.
The titanium pin buckle with black treatment offers straightforward adjustment through the strap’s different holes and keeps the fastening system relatively simple, without adding the bulk of a deployant clasp.
With formal clothing, the watch remains far from discreet. Its pronounced extremities and the visual impact of the construction make it more natural with a looser cuff and in settings where the watch can remain visible. It is not designed to disappear beneath a sleeve, but to maintain a prominent role within the overall look.

The Epic X Black Titanium interprets the contemporary skeleton watch by prioritizing identity and mechanical spectacle over versatility. The project finds its coherence primarily in the relationship between movement and design: the mechanics do not appear as an element added to a conventional base, but directly determine the face of the watch.
The compromises stem from the same approach. The visual richness reduces immediate legibility, its sporting character does not coincide with that of a true water-oriented model, and everyday ownership requires greater involvement than an automatic solution. Its strong wrist presence also deliberately narrows its audience compared with a more versatile luxury sports watch.
With an indicative launch price in the region of 24,000 euros / 26,000 dollars, the value proposition cannot be measured by the number of available functions. The buyer is primarily paying for a strongly characterized construction, mechanics designed to be observed, and the maison’s distinctive stylistic language. If you are looking for numerous complications or maximum versatility, the proposition is difficult to justify; if, on the other hand, you consider skeleton architecture and visual impact central elements in your choice, it offers a clear degree of design coherence.
The verdict is that of a deliberately specialized luxury skeleton sports watch: strong in identity and in the integration between mechanics and design, but unwilling to make the compromises required to become a universal timepiece. Its overall value lies precisely in its ability to offer a highly specific aesthetic and mechanical experience, aimed at those who prefer a distinctive personality over absolute versatility.
