During the past few weeks, I had the opportunity to test the Delma Quattro, a truly unique timepiece. At first glance, it appears to be a standard dive watch with its conspicuous rotating bezel and sturdy case. However, this watch harbors a hidden surprise—a clever mechanism located on the side of its case. With a small latch engaged, the watch head springs free from its secure cradle integrated into the bracelet. Delma refers to this innovation as the Rapid Bracelet Exchange System, enabling divers to effortlessly transition the case between a bracelet, a rubber strap, or a custom decompression plate provided by Delma.
In the realm of watch design, incorporating a detachable head brings forth a range of design challenges. In this review, I aim to assess how well Delma has tackled these challenges. However, before delving into that, it is important to question the practicality of this specific implementation of the quick-change strap feature. Having spent considerable time with the Quattro, I find myself uncertain about its viability. Let’s consider other proprietary systems employed by watch brands to facilitate strap and bracelet changes. Typically, the functionality resides within the strap itself rather than the watch case. In essence, users are usually instructed to press a button on an endlink or, in a simplified version, slide a small lever on a quick-release spring bar. Although these solutions lack tactile satisfaction, they do provide convenience and swiftness.
Contrarily, Delma proposes engaging directly with the watch head. Readers, this process is more cumbersome than it may initially appear. With the Quattro, disengaging the latch and subsequently twisting the head off the bracelet’s cradle is relatively straightforward: manipulating the small latch elevates a minuscule metal bar that secures the watch head in place. A clockwise twist then detaches the watch head from the bracelet. The idea behind this design is to allow users to affix the Quattro head onto another Delma strap mechanism (the Quattro comes with both a bracelet and a rubber strap, although I only had access to the bracelet during my evaluation). Alternatively, it can be mounted onto the aforementioned decompression table, specifically designed to aid saturation divers when transitioning from helium-rich environments they operate in.
It involves aligning the head precisely with the bracelet and twisting it counterclockwise to secure it back in position. Two issues arise in this process. Firstly, determining the exact point where the locking mechanism engages proves to be challenging. Secondly, I faced the problem of inadvertently turning the dive bezel while attempting to remount the watch head on the bracelet. Although it is possible to avoid moving the bezel, it requires positioning your fingers around the watch head in a way that makes achieving the ultimate goal of attaching it to the bracelet even more difficult.
In terms of convenience, the Delma Quattro falls short among quick change strap systems that provide similar functionality, if not the same methodology. Quick change systems inherently possess weaker points compared to traditional spring bars. While no solution is flawless, and stories about watches detaching from various strap or bracelet attachments are not unheard of, Delma’s system instills confidence once the head is correctly placed.
I can envision individuals being drawn to this watch based solely on its aesthetics. It possesses an appealing appearance and undeniably exhibits solid craftsmanship, even if some of its unique functionalities feel a bit cumbersome. The dial is highly legible, featuring large luminescent markers for each hour and clear minute markings, complemented by red Arabic numerals at five-minute intervals for emphasis and visual aid. Additionally, the Quattro’s bezel stands out as my favorite feature.
The timepiece boasts a generously sized case, measuring 44mm, which gives it a substantial presence. However, the relatively shorter lugs prevent the overall length from exceeding 50mm, making the Quattro remarkably wearable. Whether you have an affinity for robust dive watches or possess a larger-than-average wrist, this watch will suit your needs. Its bracelet follows a simple yet elegant Oyster style design, featuring a finely crafted milled clasp with three micro adjust points and a twin push button release. The meticulous machining of the watch exhibits brushed and satin finishes throughout, devoid of any ostentatious elements. Clearly, the Quattro embraces its identity as a practical tool watch.
With a water resistance rating of 500 meters, the Quattro firmly establishes itself within the realm of professional divers’ timepieces. Notably, the case incorporates a helium escape valve located on the 9:00 side. This feature, often regarded as a mere gimmick on many other dive watches, feels entirely appropriate and functional in the case of the Quattro. While I cannot personally vouch for its utility as a saturation diver, it’s evident that Delma has carefully considered a specific use case for the Quattro.
Even if watches of this nature do not always achieve resounding success, I find great value in testing them firsthand. I sincerely hope that Delma and other like-minded brands continue to push the boundaries by exploring new and unconventional approaches to watch design, along with all the accompanying accessories. Even if these endeavors occasionally yield mere gimmicks, they still provide immense enjoyment and contribute to a landscape that yearns for more intriguing timepieces.
