1969 represents a milestone in the history of watchmaking, a year that forever revolutionized the way we understand time. That year saw the birth of the Doxa Sub 300T Conquistador, a watch that not only defined an era but also introduced fundamental innovations for the world of diving. Among these was the helium safety valve, a technical detail that allowed professional divers to explore the most extreme depths without compromising the functionality of their watch.
After fifty years of history, Doxa decided to celebrate this masterpiece by relaunching the Sub 300T in 2019, a tribute that revived not only the name but also the soul of a model that made all the difference. This return is not simply a vintage reinterpretation, but an update that blends tradition and innovation, reaffirming the brand's commitment to creating robust, reliable, and accessible watches, without sacrificing the distinctive character that makes them unique.
The new Sub 300T stands out above all for its extraordinary color palette, which faithfully reproduces the original colors of the era but makes them more vivid and contemporary. The famous "Professional" orange remains the most immediately recognizable signature, a bold and aggressive color that guarantees visibility and personality. Alongside it, the bright yellow of the "Divingstar" and the vibrant turquoise of the "Aquamarine" stand out, hues that bring freshness and dynamism to an already iconic design. The deep blue of the "Caribbean" and the elegant silver with sunburst finish of the "Searambler" add a touch of refinement, while the intense black of the "Sharkhunter" recalls a timeless classic, perfect for those seeking a more understated yet striking look.
Each version of the Sub 300T retains the distinctive features of the Doxa dial: highly legible three-dimensional indexes, classic-shaped hands, and a semi-sectoral layout for easy reading in any conditions. The whole is enhanced by generous application of Super-LumiNova, which illuminates the watch when diving or in low-light conditions, underscoring the technical soul of this instrument.
The cushion-shaped case, a distinctive Doxa signature, stands out with its balanced dimensions of 42.5 millimeters in diameter and a thickness of 14 millimeters, perfect for those seeking a solid yet comfortable watch. The scratch-resistant sapphire crystal protects the dial with elegance and durability, while the robust water resistance up to 1,200 meters makes the Sub 300T a reliable companion even on the most demanding dives.
On the technical side, the beating heart of this diver's watch is the ETA 2824-2 automatic movement, a caliber known for its reliability and precision. In addition to its solid performance, the movement is adorned with exclusive Doxa finishes, underscoring the attention to detail even beneath the transparent case back, which allows you to admire the mechanical workings of the watch.
The Sub 300T is available with two strap options: a classic "beads of rice" steel bracelet, combining vintage style and comfort, and a modern FKM rubber strap, color-coordinated with the dial for a sporty and functional look. Both options offer a secure and comfortable fit, designed to accompany the watch in any situation.
Ultimately, the Doxa Sub 300T is not just a timepiece, but a piece of watchmaking history that continues to live on and excite. It is a celebration of technical evolution and an unmistakable style, capable of captivating diving enthusiasts and admirers of watches with a bold, original character alike. Its vibrant presence on the wrist is a constant reminder of a glorious past and, at the same time, an invitation to explore new horizons, with the security of always having a faithful, high-performance companion at your side.
