DOXA SUB 300 Ti5 Clive Cussler: A Titanium Tribute To An Adventure Icon
The original SUB returns in Grade 5 titanium, honouring Clive Cussler with a limited edition of 300 pieces.
The DOXA SUB 300 Ti5 Clive Cussler pays tribute to Clive Cussler. A numbered limited edition created for what would have been the author and maritime explorer’s 95th birthday. The watch returns to the original SUB 300, the foundational DOXA dive watch introduced in 1967, and reinterprets it in Grade 5 titanium for a lighter, stronger and more contemporary expression.
The connection feels natural. Cussler’s adventures, through Dirk Pitt and NUMA, helped define DOXA’s presence in popular culture, and the family’s ongoing relationship with the brand gives this edition a deeply personal dimension. With its COSC certification, new two-level dial architecture and vintage-inspired Dive Flex strap, the watch balances tribute and technical credibility.

A Return To The Original SUB
The choice of the SUB 300 is symbolic. It is the watch that started the DOXA SUB story, and the model that first brought a professional-grade dive watch to a broader public. For this edition, DOXA preserves the icon’s core identity while recasting it in Grade 5 titanium, a material that matches the spirit of exploration through its lightness, strength and corrosion resistance.
The case measures 42.5 mm by 45 mm and has a thickness of 13.4 mm. Its Grade 5 titanium construction extends to the crown and screw-down caseback, while the overall package remains water-resistant to 300 metres.

A New Two-Level Dial
The headline design innovation is the dual-plane dial architecture. DOXA builds the dial from two superimposed Grade 5 titanium layers, creating depth and dimensionality without sacrificing legibility.
The lower layer carries the Super-LumiNova-coated hour markers and minute track. Above it, the upper dial is laser-cut with openings that precisely reveal the luminous elements below, including the date aperture and minute markers. The result is a dial that feels technical and architectural, yet still fully functional in low light.
The sandblasted finish keeps the presentation understated. Rather than competing with the watch’s purpose, the layered construction gives it a subtle sense of motion and depth, much like looking beneath the surface of the sea.

DOXA Codes And Clive Cussler Details
The watch keeps the essential SUB language intact. DOXA’s patented unidirectional rotating bezel remains, with a dual scale that correlates depth and dive time. The outer ring uses orange indications for depth, while the inner ring uses black markings for dive time.
The oversized minute hand is finished in DOXA orange, staying faithful to the brand’s most recognisable visual code. All dive-related displays are coated with Super-LumiNova, ensuring strong visibility in poor conditions.
The date window at 3 o’clock includes a Clive Cussler-specific detail: the numerals 15, 7 and 31 are highlighted in orange, referencing his birth date. On the caseback, the NUMA emblem, COSC certification and individual numbering reinforce the edition’s identity.
Movement And Wearability
Inside, the watch is powered by a Swiss Sellita SW200-1 automatic movement decorated by DOXA. It runs at 28,800 vibrations per hour, contains 26 jewels and offers a power reserve of approximately 38 hours.
The movement is COSC-certified, which fits the watch’s emphasis on precision and reliability. Combined with the screw-down crown, titanium caseback and robust 300-metre water resistance, the SUB 300 Ti5 Clive Cussler remains very much a real dive watch rather than a commemorative object alone.
It is fitted with a black Dive Flex rubber strap with a tropical-inspired perforated pattern that nods to 1960s dive watches. The look is vintage in spirit, but the performance remains very current.

Limited Edition And Support For NUMA
This edition is limited to 300 numbered pieces, a change from the originally planned 95-piece concept that was expanded due to demand. It will be available through DOXA’s website and, for the first time, through authorised DOXA retailers.
A portion of the proceeds will support NUMA, the National Underwater and Marine Agency founded by Clive Cussler. That charitable link gives the project a broader purpose, tying the watch not only to Cussler’s fiction but also to his real-world maritime legacy.

Conclusion
