Arsène Lippens Scheletrato Opaco

The  Scheletrato Opaco is one of the most premium offerings in the Arsène Lippens catalogue. While skeletonised watches are appreciated for their mechanical transparency and architectural depth, many can sometimes appear overly industrial and devoid of personality. The Scheletrato Opaco, however, strikes a more nuanced balance. Despite its open-worked architecture, the design manages to retain a certain softness and elegance. Personally, I’ve never been drawn to skeletonised dials - they’ve simply never been my thing. Yet this is the first time a skeletonised watch has genuinely captured my attention. The Scheletrato Opaco doesn’t just reveal its mechanics; it shapes them into a cohesive aesthetic that feels intentional, stylish, and surprisingly wearable.

Case and Dial: Skeleton Architecture With a Stylish Character

Like all other Arsène Lippens watches, the Scheletrato Opaco also features a stepped bezel. It is one of the design elements that gives the watch a subtle vintage character while serving as a recognisable feature across much of their collection.

The case shares its profile with the Visionario chronograph and measures 39.5 mm in diameter, 45.5 mm lug to lug, and 13.5 mm in thickness. Crafted from 316L stainless steel, the proportions feel compact and well suited to the brand's vintage-inspired design language. Turning the watch over reveals an exhibition caseback that provides an unobstructed view of the fully skeletonised Valjoux 7750 movement. Protected by a sapphire crystal, the movement is complemented by a custom open-worked rotor bearing the "AL" initials. Surrounding the display is a distinctive twelve-sided (dodecagonal) caseback, a subtle architectural detail that gives the watch a more bespoke and luxurious appearance.

The skeletonised dial construction creates a strong sense of depth, revealing much of the movement beneath while maintaining a well-organised layout. Four sub-dials are arranged across the display, comprising the running seconds at 9 o'clock, the date at 3 o'clock, a 12-hour chronograph counter at 6 o'clock, and a 30-minute chronograph counter at 12 o'clock. The placement of texts on the dial has also been carefully considered. Both the Arsène Lippens logo and the "Swiss Made" inscription are positioned on the chapter ring — leaving the unobstructed view of the skeletonised movement to serve as the visual centrepiece of the dial.

Colour plays an important role in the design. The chapter ring that frames the dial and the sub-dials adopt the same blue tone, giving the watch a cohesive appearance. Heat-blued central chronograph seconds hand provides another subtle splash of blue colour. Beneath the skeletonised architecture, sandblasted silver-grey bridges contrast with gold-toned gears. The cool silver-grey architecture lends the watch a purposeful, technical character, while the blue accents and warm gold gears soften the overall appearance. The result is a skeletonised chronograph dial that feels mechanically fascinating without sacrificing refinement or style.

The Mechanical Heart: The Legendary Valjoux 7750

Powering the Scheletrato Opaco is a modified, fully skeletonised Valjoux 7750 automatic chronograph movement, one of the most respected chronograph calibres in Swiss watchmaking. Introduced in the 1970s, the Valjoux 7750 has earned a reputation for exceptional reliability and robustness, making it a favourite among Swiss watch manufacturers. Over the past five decades, it has appeared in watches from renowned luxury brands including Breitling, IWC, and TAG Heuer, cementing its status as one of the industry's most iconic automatic chronograph movements.

Operating at 28,800 vibrations per hour (4 Hz) and providing a 48-hour power reserve, the movement combines proven reliability with the level of performance expected from a respected Swiss chronograph calibre.

Colourways and Strap Variants

Arsène Lippens Scheletrato Opaco is offered in two colour variants: the blue variant named Blu Opaco and the dark gray variant named Grigio Opaco. While both share the same skeletonised architecture and overall design language, the choice of accent colours gives each watch a slightly different personality. The blue version (which is also my favourite) offers a more vibrant appearance, while the grey variant adopts a more understated aesthetic.

Both versions can be ordered on a sailcloth strap matched to the dial colour or paired with a stainless steel beads-of-rice bracelet.

Final thouoghts: A Contemporary Skeleton Chronograph for the Modern Collector

The Scheletrato Opaco from Arsène Lippens is a compelling interpretation of the modern Swiss-made skeleton chronograph, successfully balancing mechanical complexity with refined design. Its compact proportions, the stepped case, fully skeletonised Valjoux 7750 movement, layered architecture, and thoughtful use of colour result in a watch that is technically fascinating, aesthetically sophisticated and wearable. With a retail price of approximately €4,979, the Scheletrato Opaco firmly occupies the luxury segment of the market. While it represents a significant investment, it offers a distinctive design, respected Swiss mechanics, and a level of individuality that sets it apart from many conventional skeletonised watches.
