Certina DS Action Diver 40.5mm

Certina is once again making a significant statement in the realm of robust sports watches with the unveiling of its DS Action Diver, now presented in a thoughtfully proportioned 40.5mm case. This new size is a direct response to contemporary preferences, broadening the appeal of a collection already renowned for its unwavering performance and durability. The introduction of these models is not merely an expansion of a product line; it signifies a continued commitment to the core principles that have defined Certina for over a century, particularly its dedication to creating timepieces that can withstand the rigors of both aquatic adventures and the challenges of everyday life.



The legacy of Certina in the demanding world of dive watches is both rich and storied, stretching back to an era when underwater exploration was rapidly advancing. The company’s reputation for producing exceptionally resilient timepieces was firmly established with the introduction of the Double Security (DS) system in 1959. This innovative approach to watch construction, which focused on enhancing both shock and water resistance, set a new benchmark for durability in the industry. It wasn't long before Certina watches became trusted instruments for adventurers and professionals alike, accompanying them on some of the most challenging underwater expeditions of the 20th century.



During the 1960s and 1970s, Certina’s dive watches were put to the ultimate test in extreme underwater missions such as the U.S. Navy's Sealab II project and the Tektite I & II underwater habitat programs. In these demanding environments, where equipment failure was not an option, Certina timepieces performed reliably, enduring immense pressure and harsh conditions. These real-world validations solidified Certina’s standing as a premier manufacturer of professional-grade diving instruments, proving that their watches were not just accessories, but essential tools for those venturing into the unknown depths. This historical context is crucial for understanding the pedigree of the new DS Action Diver 40.5mm.



Building upon this formidable foundation, Certina has now introduced the "New DS Concept Extreme Shock Resistance" with the launch of the DS Action Diver 40.5mm. This represents the next evolutionary step for the iconic DS system, engineered to offer an even greater level of resilience and performance that dramatically surpasses the stringent requirements of ISO 1413, the standard for shock-resistant watches. Certina’s engineers have pushed the boundaries to such an extent that during testing, the very equipment used to simulate extreme g-forces reached its operational limits before the watch showed any signs of compromise. This speaks volumes about the sheer toughness embedded within this new generation of timepieces.



The "New DS Concept Extreme Shock Resistance" enhances the already robust nature of the traditional DS system by incorporating three new key features specifically designed to augment its protective capabilities. The first of these innovations focuses on further securing the intricate automatic movement within the watch case, ensuring it remains stable and unaffected by sudden, violent accelerations or decelerations. The second feature is engineered to reinforce the dial's stability, preventing any potential displacement or damage that could occur under extreme impact. Finally, the third enhancement involves strengthening the watch glass, providing an additional layer of defense against direct shocks and pressures that could compromise the watch's integrity. These advancements, combined with the established DS principles, work in concert to deliver a timepiece that is truly built for the unexpected.



The new DS Action Diver 40.5mm collection debuts with four distinct variations, each offering a unique take on this robust platform. Two models are crafted from durable stainless steel, providing a classic and resilient housing for the advanced mechanics within. One of these stainless steel versions features a deep black dial, perfectly matched with a black ceramic bezel insert, creating a look of focused utility. This particular model offers a choice between a robust stainless steel bracelet or a more casual, yet equally durable, striped black and beige NATO fabric strap, catering to different stylistic preferences and functional needs.



The other stainless steel model presents a strikingly different aesthetic with its crisp white dial, also complemented by a matching white ceramic bezel. This combination lends the watch an exceptionally clean and legible appearance, with dark hands and markers providing sharp contrast against the bright background. Mounted on a stainless steel bracelet, this version offers a fresh and contemporary take on the classic dive watch design, suitable for a variety of settings, from underwater exploration to urban environments. The cohesive color matching between the dial and bezel on these steel models underscores a meticulous attention to design detail.



For those seeking a lighter yet incredibly strong timepiece, the collection includes a standout edition crafted from titanium. This model features a captivating blue dial, a hue often associated with the depths of the ocean, which is mirrored by a blue ceramic bezel insert. Titanium’s inherent properties of being lightweight and highly corrosion-resistant make it an ideal material for a serious dive watch. The muted, satin finish of the titanium case and bracelet further enhances its purposeful and modern appeal, offering a distinct alternative to the polished and brushed surfaces of its steel counterparts.



Visually, the DS Action Diver 40.5mm watches exude a sense of capability and precision. The 40.5mm diameter case strikes an excellent balance, offering substantial presence on the wrist without feeling overly cumbersome, a dimension many enthusiasts will find ideal. The case height is a reasonable 14.10mm, allowing it to sit comfortably, while the 20.00mm lug width provides a solid stance and compatibility with a wide range of strap options. The overall architecture speaks of a tool built for purpose, with strong lines and a clear emphasis on functionality.



A key feature of any serious dive watch is its unidirectional rotating bezel, and the DS Action Diver 40.5mm excels in this regard. The bezels are crafted from high-performance ceramic, a material lauded for its exceptional scratch resistance and robustness. Whether in black, white, or blue, these ceramic inserts feature clearly marked dive scales, essential for timing immersions safely. The precise click of the bezel as it rotates offers tactile feedback, assuring the user of its quality construction. The luminous pip at the 12 o'clock position on the bezel further aids in dive timing in low-light conditions.



The dials of the DS Action Diver 40.5mm are designed with maximum legibility as a priority. Large, applied indices and generously proportioned hands are all treated with a significant application of Super-LumiNova. This luminous compound ensures that the time, as well as critical dive information, remains clearly visible in the darkest underwater environments or during nighttime activities. The date window, typically positioned at 3 o'clock, is neatly integrated, providing practical daily functionality without cluttering the dial’s primary purpose of clear time indication. The seconds hand on some variants, like the black dial model with the fabric strap, features a distinct yellow tip, adding a subtle flash of color and enhancing its visibility as it sweeps around the dial, confirming at a glance that the watch is operational.



Protecting the meticulously designed dial is a sapphire crystal, renowned for its superior scratch resistance, second only to diamond. Certina has further enhanced the clarity of this crystal by applying an anti-reflective treatment to one side. This coating significantly reduces glare and reflections, ensuring that the dial can be read easily from various angles and under bright light conditions, which is particularly beneficial when submerged or in sunny environments. The slight dome or flat profile of the crystal is seamlessly integrated into the bezel and case design, contributing to the watch's overall sleek yet sturdy profile.



At the heart of each DS Action Diver 40.5mm beats the impressive Powermatic 80.611 automatic movement. This Swiss Made calibre, sourced from ETA, is a testament to modern watchmaking innovation. Its most notable feature is an extended power reserve of up to 80 hours. This means the watch can be taken off for a full weekend and will still be running accurately when picked up again on Monday morning, a convenience highly valued by contemporary watch wearers. Such a power reserve is considerably longer than that offered by many standard automatic movements.



Furthermore, the Powermatic 80.611 movement incorporates a Nivachron balance spring. This advanced alloy offers significant advantages, including increased resistance to magnetic fields, which are increasingly prevalent in our modern environment and can adversely affect a mechanical watch's accuracy. The Nivachron balance spring also boasts excellent resistance to temperature variations and superior shock resistance, contributing further to the overall precision and durability of the timepiece. The reliability and performance of this movement are key to the DS Action Diver's appeal as a trustworthy companion.



True to its name, the DS Action Diver 40.5mm is engineered for serious underwater use. It boasts a substantial water resistance rating of 300 meters (or 30 bar/1000 feet). This capability is not just a nominal figure; the watch is certified according to the stringent ISO 6425:2018 standard for professional dive watches. This international standard outlines a series of demanding tests that a watch must pass to be officially recognized as a diver's instrument, covering aspects like water resistance, legibility, bezel functionality, and resistance to magnetism, shocks, and strap/bracelet robustness. Achieving this certification underscores Certina's commitment to producing watches that meet the highest benchmarks for safety and reliability in aquatic environments.



The choice of strap or bracelet significantly impacts a dive watch's utility and comfort. The stainless steel models are available with a meticulously crafted three-link stainless steel bracelet, featuring a secure folding clasp with a diver's extension. This allows the bracelet to be easily adjusted to fit over a wetsuit sleeve. The titanium model is paired with a matching titanium bracelet, offering the same secure clasp system but with the added benefit of reduced weight. For a different feel and aesthetic, the black dial stainless steel version also offers a durable NATO-style fabric strap, known for its security (as the watch head remains attached even if one spring bar fails) and quick-drying properties.



Turning the watch over reveals a solid case back, a common feature in dive watches that contributes to their high water resistance. This protective barrier is typically adorned with Certina’s distinctive turtle emblem. This symbol, deeply rooted in the brand's history, represents longevity, resilience, and, fittingly, the brand’s profound connection to the aquatic world. The turtle motif is more than just decoration; it’s a visual reminder of the robust DS Concept and the watch’s inherent ability to protect its intricate inner workings from the elements.
