Chronoswiss Chronograph Rattrapante CH7322 Review

The Architecture of Ambition: An Analysis of the Chronoswiss CH7322

To understand the Chronoswiss Chronograph Rattrapante, one must first understand the man behind the brand: Gerd-R. Lang. Lang was a veteran of Heuer during the golden age of chronographs, and when he founded Chronoswiss in 1983, he did so with a singular mission—to preserve the mechanical traditions that the quartz revolution had nearly extinguished. The Reference CH7322 is perhaps the purest expression of that mission, marrying a robust industrial base with the high-wire act of a split-seconds complication.

The Case: A Study in Neo-Classical Design

The case of the CH7322 is a masterclass in detail. Measuring 38mm in diameter, it adheres to the classical proportions favored by Lang. However, its presence is magnified by the signature Chronoswiss design elements. The bezel and the case back feature a fine coin-edge knurling, a nod to the trench watches of the early 20th century. This is not merely decorative; it provides a visual texture that breaks up the polished surfaces of the mid-case.

The lugs are equally distinctive. Long and straight, they are fitted with functional screws to secure the strap, a system Chronoswiss refers to as 'Autopod.' This choice reflects a commitment to mechanical integrity over the convenience of standard spring bars. Then, there is the crown. The oversized onion crown is the brand's most recognizable signature, designed for ease of use even while wearing gloves—a romantic callback to the era of pioneer aviation.

One cannot discuss the case without addressing its thickness. At 15.3mm, the CH7322 is undeniably tall. This height is the necessary byproduct of the Caliber C.732. Accommodating a split-seconds module on top of an automatic chronograph movement requires physical space. On the wrist, this creates a 'instrument-like' feel. It does not hide; it announces itself as a piece of serious engineering.

The Dial: Elegance in Silver and Blue

The dial of the CH7322 is crafted from solid .925 sterling silver, a rarity in modern watchmaking where brass is the standard. The surface is finished with a delicate matte texture that absorbs light, providing a perfect backdrop for the blued steel hands. The hands themselves are in the 'Poire Stuart' style, characterized by their graceful, teardrop-shaped tips.

The layout is a traditional tri-compax arrangement: small seconds at 9 o'clock, a 30-minute counter at 12, and a 12-hour counter at 6. The date window is integrated into the 3 o'clock position, providing daily utility without disrupting the visual balance. The most captivating element, however, is the dual central chronograph hands. In their resting state, they appear as a single hand. Only when the rattrapante pusher at 10 o'clock is engaged do they separate, allowing the user to time two simultaneous events or record intermediate laps.

The Movement: The Heart of the Rattrapante

At the core of the CH7322 lies the Caliber C.732. While its architecture begins with the legendary Valjoux 7750—a movement known for its 'bulletproof' reliability—the modifications are extensive. Chronoswiss collaborated with the complication specialists at Alfred Rochat & Fils to integrate the split-seconds module. This is a significant horological feat; the rattrapante is widely considered one of the most difficult complications to manufacture and regulate, often ranked alongside the tourbillon and the minute repeater.

Viewing the movement through the sapphire case back reveals a level of finishing that punches far above the watch's price point. The plates are decorated with perlage (circular graining), and the screws are thermally blued. The rotor is skeletonized and finished with Côtes de Genève. Technically, the C.732 operates at 28,800 vibrations per hour, ensuring a smooth sweep of the chronograph hands. The engagement of the split-second function is crisp, a result of the precise tensioning of the rattrapante clamps that halt the second hand.

The Rattrapante Function: How It Works

The term 'Rattrapante' comes from the French 'rattraper,' meaning 'to catch up.' In the CH7322, the chronograph is started via the pusher at 2 o'clock. Both hands move in unison. When the pusher at 10 o'clock is depressed, the lower hand stops, allowing the user to read an intermediate time, while the upper hand continues its journey. Pressing the 10 o'clock pusher again causes the stopped hand to instantly 'catch up' to the moving one. This mechanical dance is facilitated by a complex system of cams and levers that must be perfectly synchronized to prevent the movement from jamming.

Wrist Experience and Practicality

Wearing the CH7322 is a tactile experience. The 'wobble' of the 7750-based rotor is present, giving the watch a sense of life on the wrist. While the 19mm lug width can be frustrating for those who enjoy swapping straps, the factory alligator leather is of exceptional quality and complements the watch's formal-yet-technical aesthetic.

In terms of versatility, the CH7322 occupies a unique middle ground. Its stainless steel construction and technical dial make it suitable for daily wear, yet its historical design cues allow it to pair seamlessly with a tuxedo or a navy blazer. It is a watch for the individual who appreciates the nuance of 'if you know, you know' horology.

Investment and Market Context

For the young collector, the Chronoswiss CH7322 represents an incredible value proposition. In a market where integrated-bracelet sports watches often see inflated prices based on hype, the CH7322 remains grounded in its technical merit. It offers a high-end complication from a respected manufacture for the price of a standard entry-level luxury diver. As the market continues to mature and collectors look toward the 'neo-vintage' era of the 1990s, the work of Gerd-R. Lang is increasingly being recognized for its pivotal role in the mechanical revival.

Final Thoughts

The Chronoswiss Chronograph Rattrapante CH7322 is a watch of substance. It does not rely on marketing gimmicks or celebrity endorsements. Instead, it relies on the strength of its engineering and the clarity of its design vision. It is a reminder that horology is, at its heart, a pursuit of precision and beauty. For those who seek a timepiece that reflects a sophisticated understanding of mechanical art, the CH7322 is a definitive choice.
