The Doxa company marks the 95th anniversary of Clive Cussler's birth with the release of a new version of its iconic diver model.
The Doxa Sub 300 Ti5 Clive Cussler retains the classic form of the 1967 Sub 300, but the case, crown, case back, and even the dial are made of grade 5 titanium. This COSC-certified chronometer is water-resistant up to 300 meters and is released as a limited edition of 300 numbered pieces.
The History of the Doxa and Clive Cussler Partnership
The connection between Doxa and Clive Cussler runs deep. In the fictional adventures of the writer, the main character Dirk Pitt regularly wears a Doxa Sub watch, and the company supports NUMA, an organization founded by Cussler for the search and preservation of historical shipwrecks. Personally, I was convinced of the significance of this partnership: previous Doxa Clive Cussler releases prompted me to explore the books, and I read several adventures of Dirk Pitt. Thanks, Doxa, for that! Now, let's take a closer look at the new model.
Features of the Doxa Sub 300 Ti5 Clive Cussler
The Sub 300 model was a logical choice for this series. Doxa introduced it in 1967 as a diver's watch for the general public, meeting professional standards. The characteristic broad-shouldered case shape and prominent decompression bezel remain central elements of the signature design.

The main innovation is the grade 5 titanium case, but the dial is equally intriguing. It consists of two overlaid titanium plates with a matte sandblasted finish. The lower plate features luminescent hour markers, while the upper plate is slightly above with laser-cut holes through which elements beneath are visible. A similar construction is used for the date window and minute markings. The small gap between the plates creates a sense of depth and shadow without overloading the display.

References to Clive Cussler are restrained. On the date disc, the numbers 7, 15, and 31 are highlighted in orange - the birth date of the writer, July 15, 1931. The titanium case back is adorned with the NUMA emblem, COSC designation, and the individual serial number of the limited series.

Design and Functional Features
The grade 5 titanium case with sandblasted and polished finish not only emphasizes strength and durability but also significantly reduces the weight of the watch. The dimensions of 42.5 × 45 mm may seem large, but thanks to the lightweight titanium case and the curved cushion shape of the midsection, the watch remains comfortable to wear and has a low center of gravity.

The dial with a two-level construction looks modern and technological while not being overloaded with unnecessary details. Orange accents on the minute hand and specific date numbers add character and make the model recognizable without detracting from its primary functionality.
The bezel with a dual scale allows precise tracking of depth and dive time, which is especially important for professional divers and underwater enthusiasts. The Super-LumiNova luminescent coating provides excellent readability in low-light conditions.

Final Impressions of the Model
The two-level titanium dial and minimalist design make the Doxa Sub 300 Ti5 Clive Cussler practical and stylish watches for everyday and professional use. The absence of excessive decorative elements aligns with the concept of tool diver watches.

The lightweight and durable grade 5 titanium case ensures comfort and reliability, while the COSC-certified movement guarantees high precision. The restrained thematic references to Clive Cussler and his legacy make this model particularly valuable for fans of the writer and collectors.
The model is available from July 15 on the official Doxa website and, for the first time, at authorized dealers. Part of the proceeds will support the NUMA organization.
Conclusion
The Doxa Sub 300 Ti5 Clive Cussler is a successful combination of classic design, modern materials, and precise mechanics. These watches are perfect for professional divers and watch enthusiasts with a passion for history and character. The limited edition and unique details make this model a worthy continuation of the legendary Sub 300 series.
