Doxa has released the SUB 300 Ti5 Clive Cussler, a limited-edition dive watch honoring the late author and explorer. According to the brand, this 300-piece series features a grade 5 titanium case and a novel dual-plane dial construction. The watch is priced at US$3,390 and supports the National Underwater and Marine Agency (NUMA).
The Evolution of Titanium in Professional Diving Watches
The transition to grade 5 titanium in the SUB 300 collection marks a significant shift for Doxa, moving away from traditional stainless steel to favor weight reduction and improved corrosion resistance. By utilizing this material for the case, crown, and caseback, Doxa maintains the 300-meter water resistance required for professional diving while significantly reducing the watch’s overall mass on the wrist.
Engineering a Dual-Layer Aesthetic
Doxa’s introduction of a dual-plane, sandwich-style dial represents a departure from the brand’s standard flat dial designs. According to company specifications, the construction features a lower layer housing the Super-LumiNova markers and minute track, topped by a laser-cut, sandblasted titanium plate.

The watch preserves the functional hallmarks of the 1967 original, including the oversized orange minute hand and the patented unidirectional dual-scale bezel. Subtle personalization includes the date window, where the numerals 15, 7, and 31 are highlighted in orange to commemorate Clive Cussler’s birth date of July 15.
Tool Watch Reliability and Heritage
At its core, the SUB 300 Ti5 is powered by the Sellita SW200-2 automatic movement.
Did you know? The connection between Doxa and Clive Cussler is rooted in the author’s novels, where his hero, Dirk Pitt, famously wore a Doxa SUB.
Market Availability and Collector Value
Each watch is individually numbered on the titanium caseback, which also features the NUMA emblem. Proceeds from the sale of these timepieces contribute to the work of the National Underwater and Marine Agency, the organization founded by Cussler in 1979 to preserve maritime history.
