Doxa has introduced a limited-edition SUB 300 in honour of novelist and explorer Clive Cussler. The Grade 5 titanium model marks what would have been Cussler’s 95th birthday while revisiting one of the brand’s most recognisable dive watches.
Cussler shared a long association with Doxa through his Dirk Pitt novels, where the fictional adventurer regularly wore a SUB dive watch during underwater expeditions. Those books helped introduce the model to readers well beyond the diving community. Cussler also founded the National Underwater and Marine Agency (NUMA) in 1979, an organisation dedicated to locating and documenting historic shipwrecks.
The limited edition keeps the SUB 300’s distinctive case design, measuring 42.5mm across and 45mm from lug to lug. Its case, screw-down crown and engraved caseback are all made from Grade 5 titanium, helping reduce weight while maintaining 300 metres of water resistance. A domed sapphire crystal and Doxa’s signature unidirectional dive bezel complete the familiar design.
Most of the visual changes are concentrated on the dial. Doxa has used a two-layer titanium construction, with the lower section carrying the Super-LumiNova markers while the sandblasted upper layer is cut away to reveal them. The result adds depth without compromising the clear legibility expected from a professional dive watch.
Several details also pay tribute to Cussler himself. The date numerals 7, 15, and 31 are printed in orange to reference his birth date of July 15, 1931, while the caseback carries the NUMA emblem alongside each watch’s individual limited-edition number. Doxa’s signature orange minute hand remains part of the design.
Power comes from a COSC-certified Sellita SW200 automatic movement, offering around 38 hours of power reserve. The watch is paired with a black Dive Flex rubber strap finished with a Grade 5 titanium pin buckle.
Limited to 300 individually numbered pieces, the SUB 300 Ti5 Clive Cussler is priced at $3,390. Part of the proceeds will support NUMA, making this release both a tribute to one of Doxa’s best-known supporters and a contribution to the maritime organisation he founded.
