Roughly two decades after it first made a substantial impression on the world of dive watches, the DOXA SUB 750T is making its return. This is not merely a re-release but a thoughtful evolution of a modern classic. The SUB 750T, known for its commanding presence, has been reimagined for the contemporary enthusiast, carrying forward its robust, professional-grade heritage while incorporating significant updates in design and wearability. It re-emerges as a testament to DOXA's enduring legacy in the specialized field of underwater timekeeping, now refined for a new generation of adventurers.
The history of DOXA is intrinsically linked to the sea. Founded in Le Locle, Switzerland, in 1889, the brand established itself as a producer of quality timepieces. However, it was in 1967 that DOXA cemented its place in horological history by introducing the SUB 300, a dive watch developed with input from professionals, including the legendary Jacques-Yves Cousteau. It was revolutionary, featuring a bright orange dial for superior underwater visibility and a patented unidirectional rotating bezel with a no-decompression dive time scale, a critical safety innovation. This spirit of purpose-built engineering continued, leading to the introduction of the original SUB 750T in 2002, a model that amplified the brand's core principles in a larger, even more capable package.

The new SUB 750T builds directly upon this lineage. The original model was celebrated for its unapologetically large 44.7mm case and a thickness of nearly 14mm, a true instrument designed for legibility and durability under extreme pressure. The 2025 version respects this bold character but introduces a significant and welcome refinement. While maintaining the confident footprint of 45mm by 47mm, the case has been skillfully slimmed down to a thickness of just 11.95mm. This reduction is a remarkable feat of engineering, creating the slimmest 45mm SUB model to date and fundamentally transforming the wearing experience without compromising its formidable presence.
This updated case architecture is a masterclass in functional design. The iconic cushion shape remains, crafted from stainless steel with a predominantly brushed finish that mitigates glare and reinforces its tool-watch credentials. Sharp, angular lines and distinct chamfers add a layer of visual complexity, catching the light in a way that highlights its precise construction. The watch feels substantial yet balanced, a direct result of the reduced thickness, which allows it to sit more comfortably on a wider range of wrists. It is a watch that still makes a statement but does so with a newfound level of ergonomic grace.

At the 3 o'clock position, a sturdy, screw-down crown ensures the integrity of the case against water ingress. This is crucial, as the SUB 750T boasts an impressive water resistance rating of 750 meters, equivalent to 2,460 feet or 75 atmospheres. This level of performance places it firmly in the category of serious, professional-grade dive watches, capable of accompanying divers on deep-sea excursions. The case is sealed with a solid, screw-in stainless steel caseback, further guaranteeing its robustness in demanding underwater environments.
Encircling the flat sapphire crystal is perhaps DOXA's most famous innovation: the patented unidirectional rotating bezel. This essential diving tool is designed for calculating and monitoring no-decompression dive times. Its outer edge is deeply serrated, providing excellent grip even when handled with wet or gloved hands. The bezel insert features two distinct scales. The outer scale, often rendered in a high-contrast color like orange, marks depth in feet, while the inner black scale marks elapsed minutes. By aligning the bezel's zero marker with the minute hand, a diver can easily track bottom time, a critical element of dive safety.

One of the most exciting aspects of this new launch is the sheer variety of options available. DOXA is releasing the SUB 750T in all eight of its signature colorways, resulting in sixteen distinct references when accounting for strap choices. This broad palette allows collectors and enthusiasts to choose a version that perfectly suits their personal style, moving the watch beyond a purely functional instrument into a form of self-expression. Every dial is designed with maximum legibility as the primary goal, a core tenet of the DOXA SUB philosophy.
The lineup begins with the quintessential Professional Orange. This is the color that made DOXA famous, chosen for its high visibility in the murky depths where colors at the red end of the spectrum fade first. It’s a vibrant, energetic dial that is pure DOXA heritage.
For a more classic, tactical look, there is the Sharkhunter Black. The deep black dial serves as a perfect backdrop for the large, luminous markers. The minute hand and bezel markings often retain a splash of orange, a nod to the brand's history and an aid to legibility.

The Whitepearl White offers a strikingly clean and modern aesthetic. The crisp white dial, paired with black-outlined hands and indices, provides superb contrast. It’s a versatile option that looks just as at home on the deck of a boat as it does 100 feet below the surface.
The Searambler Silver Grey presents a more understated and sophisticated choice. Its sunray silver-grey finish plays with the light beautifully, giving the watch a dynamic quality that shifts with the angle of view.

The Caribbean Navy Blue evokes the deep, mysterious tones of the open ocean. It's a rich and saturated blue that provides a handsome alternative to the traditional black dial, often paired with orange accents for that signature DOXA look.
For those who prefer a bolder statement, the Divingstar Yellow is an unmissable option. This bright, sunny yellow is cheerful and sporty, ensuring the watch will be a conversation starter wherever it goes.
The Aquamarine Turquoise is a fresh and contemporary color that has become a fan favorite. Its light, vibrant hue is reminiscent of tropical waters and adds a playful, modern edge to the rugged SUB 750T case.

Finally, the Sea Emerald Dark Green introduces a rich, complex color to the family. The deep green dial has a sunburst finish that radiates from the center, giving it a sense of depth and luxury that complements its tool-watch capabilities.
Regardless of the color chosen, the dial layout is consistent and clear. Large, block-shaped hour markers are paired with a distinctive handset featuring an oversized minute hand and a smaller, "dwarf" hour hand. This design prioritizes the minute hand, as it is the most critical indicator for a diver tracking elapsed time. A simple date window is neatly integrated at the 3 o’clock position, adding everyday functionality. All critical diving elements—the hands, indices, and bezel markers—are generously coated with Super-LumiNova®, ensuring they glow brightly for optimal legibility in low-light conditions.
Powering the new SUB 750T is a reliable and proven Swiss-made automatic mechanical movement, the Sellita SW300. This choice underscores the watch's purpose as a dependable tool. The movement operates at a frequency of 28,800 vibrations per hour (4 Hz), which provides a smooth sweep to the seconds hand and contributes to its accuracy. It features 25 jewels and offers a very practical power reserve of approximately 56 hours, meaning the watch can be set down for a weekend and will still be running on Monday morning. DOXA also notes that the movement is decorated, a fine touch that speaks to the overall quality of the timepiece.

The connection between the watch and the wearer is completed by the choice of two excellent strap options. The first is the iconic stainless steel "beads of rice" bracelet. This bracelet is a DOXA hallmark, renowned for its supreme comfort and vintage appeal. The small, polished center links contrast with the brushed outer links, creating a design that articulates beautifully around the wrist. It is fitted with a secure folding clasp that features an engraved "DOXA fish" emblem and a practical diving suit extension, allowing it to be easily worn over a thick wetsuit.
Alternatively, the SUB 750T is available on a high-quality FKM rubber strap. This option provides a lighter, sportier feel and is color-matched to the dial of the watch. The rubber strap is soft, durable, and perfectly suited for aquatic activities. It offers a more modern aesthetic and is an excellent choice for those who prioritize lightweight comfort during active pursuits.

The revitalized DOXA SUB 750T is a compelling proposition. It successfully bridges the gap between its historical identity as a professional diving instrument and the demands of the modern watch enthusiast. By refining the case to be significantly slimmer, DOXA has enhanced its daily wearability without sacrificing an ounce of its legendary toughness or water resistance. It remains a true tool watch, built to perform in the most challenging environments imaginable.
The new DOXA SUB 750T is available for pre-order starting at the end of September through authorized DOXA retailers worldwide and directly from the brand's website. The pricing reflects the watch's quality and Swiss-made pedigree. The version on the color-matched rubber strap is priced at $2,750.00 USD, while the model equipped with the classic stainless steel "beads of rice" bracelet is priced at $2,790.00 USD. This launch marks a significant new chapter for a beloved model, ensuring the legend of the SUB 750T will continue for decades to come.
