The Story Behind It
Fifteen July is not an arbitrary date.
DOXA chose Cussler’s 95th birthday to return its foundational reference — the SUB 300, introduced in 1967 as the first dive watch for the general public — to production in Grade 5 titanium. Cussler, who passed away in February 2020, placed a DOXA SUB on the wrist of his hero Dirk Pitt across more than 50 novels, an act that introduced the brand to readers in over 100 countries. His son, Dirk Cussler, remains close to the brand. “This titanium SUB 300 captures something of who he truly was, and I’m deeply grateful to DOXA for honoring his memory with such authenticity,” said Dirk Cussler, son of Clive Cussler and author.
The edition was originally conceived as 95 pieces — one per year of Cussler’s life. Strong demand prompted DOXA to raise that figure to 300, a number that mirrors the model name and the watch’s depth rating. Each caseback carries the emblem of NUMA (National Underwater and Marine Agency), the COSC certification, and individual numbering (XXX/300). Part of the proceeds will support NUMA’s ongoing work preserving historically significant shipwrecks.
Design & Mechanics
The dual-plane dial is the defining technical contribution of this edition.
Two Grade 5 titanium dials sit in superimposition. The lower carries the Super-LumiNova hour markers and minute track; the upper is laser-cut with apertures that align precisely with each marker below. The gap between the two planes produces a shadow and a sense of depth that shifts with the angle of light. Up close, the sandblasted finish reads as functional rather than decorative — which is precisely the point for a dive watch with 300-metre water resistance.
The oversized orange minute hand, a historic SUB signature, retains immediate priority on the dial. The outer bezel ring repeats the orange tone for its depth scale, while the inner ring uses black for dive time. Three date numerals — 15, 7 and 31, corresponding to Cussler’s birth date — appear in DOXA orange within the 3 o’clock date window. The Sellita SW200-1 automatic movement, COSC-certified, provides the mechanical foundation, beating at 4.0 Hz with exclusive DOXA decorations applied to its bridges.
On the Wrist
Grade 5 titanium makes a measurable difference in practice.
At 42.50 mm across and 13.40 mm thick, this is a substantial case by any measure. The Grade 5 titanium construction — covering the case, dual-plane dial, screw-down crown and caseback — keeps the weight well below that of a comparable steel dive watch. For the GCC collector, who wears watches across a broad range of environments, the comfort advantage on the wrist over long periods is real. The black Dive Flex rubber strap, perforated in a 1960s tropical style, completes the vintage character without sacrificing grip or durability.
The COSC-certified movement inside a Grade 5 titanium case with 300-metre water resistance places this edition firmly in the category of a dive watch for the general public that carries no practical compromise — exactly the ambition of the 1967 original.
Where It Sits in the Collection
The SUB 300 Ti5 Clive Cussler is the first titanium model in the DOXA line since the brand’s earlier Grade 5 experiments, and it sits alongside DOXA’s carbon models as one of the lightest watches the brand produces.
For GCC collectors, the pricing — CHF 2,890 — positions this clearly below comparable COSC-certified titanium dive watches from larger Swiss houses, while the 300-piece limit and the NUMA connection provide a clear collecting rationale beyond the specifications alone. Distribution through authorised DOXA retailers for the first time on a tribute edition widens access without diluting the numbered character of the piece.
Jan Edöcs, CEO of DOXA, noted: “Lightweight, exceptionally durable, demanding to work with and built to last, this material felt like the natural choice for an edition dedicated to Clive Cussler.”
