Legendary
novelist and adventurer Clive Cussler, who shared his passion for
Doxa SUB watches through his hero Dirk Pitt, would have celebrated his
95th birthday today, July 15. Doxa marks the occasion by returning to
its origins — the SUB 300, the foundational watch introduced in 1967 —
reimagined for this special edition in Grade 5 titanium.

The
choice of model is deliberate. The SUB 300 is where it all began.
Introduced in 1967, it was the first dive watch designed for the general
public while meeting the demands of professional diving.

The
choice of material is equally meaningful. Grade 5 titanium — lighter,
stronger and highly corrosion-resistant — naturally reflects the spirit
associated with

This
edition is limited to 300 numbered pieces, in direct reference to the
model itself. Originally conceived as a series of 95 watches in tribute
to what would have been Clive Cussler’s 95th birthday this year,
production was exceptionally increased to 300 pieces in response to
strong demand. The SUB 300 Ti5 Clive Cussler will be available on
doxawatches.com and – this is a first – at authorized DOXA retailers.

This opens a broader access to this tribute edition, while preserving
the exclusive character associated with DOXA special editions. Part of
the proceeds will go to support the work of NUMA, founded by Clive
Cussler.
A first: the dual-plane dial architecture, creating depth and dimension
The SUB 300 Ti5 Clive Cussler introduces
an entirely new dial architecture. It is, in fact, composed of two
superimposed dials, both crafted from Grade 5 titanium, which together
create a layered effect combining technical precision with visual
impact.

The
lower dial carries the Super-LumiNova® hour markers and the minute
track. On the upper dial, positioned a short distance above the first,
openings matching the exact proportions of the hour markers — with a
central aperture aligned with the index beneath and two lateral cut-outs
reproducing its full geometry — have been laser-cut, revealing the
luminous elements below. The date aperture and minute markers are
produced using the same technique.

The
effect is twofold: the infinitesimal space between the two levels
creates a subtle impression of depth, while the interplay of light and
shadow — perceptible both in daylight and in low-visibility conditions —
enhances the dial’s presence without ever compromising legibility. With
its sandblasted finish, it retains its full functional character, while
inviting the eye to return — much like one watches the surface of the
ocean, knowing that what matters most lies beneath.
Legibility, versatility, reliability — the fundamentals remain intact
Like the inaugural model introduced in
1967, the SUB 300 Ti5 Clive Cussler is water-resistant to 300 meters and
equipped with DOXA’s patented unidirectional rotating bezel. Its dual
scale correlates depth and dive time, helping divers remain within the
no-decompression limits established by the US Navy.

Beneath
the scratch-resistant anti-reflective “glass box” sapphire crystal, all
dive-related displays are coated with Super-LumiNova®, ensuring
excellent legibility in low-visibility conditions. The oversized minute
hand — a historic SUB signature — is rendered in Doxa orange (a nod to
the original) to immediately draw the eye to the most critical
information.

The
depth indications on the bezel’s outer ring also feature this
distinctive orange tone, contrasting with the black markings of the
inner ring dedicated to dive time. The date window at 3 o’clock
incorporates a detail unique to this edition: the numerals 15, 7 and 31
appear in Doxa orange, referencing Clive Cussler’s birth date.

Powered
by a Swiss automatic movement with exclusive Doxa decorations beating
at 28,800 vibrations per hour (4.0 Hz), the watch delivers a comfortable
power reserve of approximately 38 hours. The screw-down caseback and
crown — both also crafted from Grade 5 titanium — complete a package
water-resistant to 300 meters (~984 feet), providing ample margin for
underwater exploration.
The return of titanium at Doxa
The SUB 300 Ti5 Clive Cussler marks the
return of Grade 5 titanium to the Doxa collection — a material renowned
for its exceptional strength-to-weight ratio, corrosion resistance and
comfort on the wrist.

The case (42.50 mm × 45.00 mm, thickness 13.40
mm), dual-plane dial, screw-down caseback and crown are all crafted from
Grade 5 titanium (Ti5), making this one of the lightest — alongside
DOXA’s carbon models — and most resilient watches the brand has ever
produced.
The caseback: a component in its own right
Also crafted from Grade 5 titanium, the
screw-down caseback bears the emblem of NUMA (National Underwater and
Marine Agency), the COSC certification and the individual numbering of
each watch (XXX/300).
The bracelet: vintage in spirit, timeless in execution
The SUB 300 Ti5 Clive Cussler is fitted
with a black Dive Flex rubber strap featuring a tropical-inspired
aesthetic, whose signature perforated pattern evokes the spirit of the
1960s, when the original SUB 300 opened the world of professional diving
to the wider public..

An enduring partnership with NUMA
In keeping with Clive Cussler’s
commitment to preserving maritime heritage, Doxa will donate part of the
proceeds from this special edition to NUMA — the National Underwater
and Marine Agency, the organization he founded in 1979 to search for and
preserve historic shipwrecks.

“The connection between Doxa and my
father was never simply a commercial partnership — it was a shared
adventure, built around the values he believed in and carried forward
today through the NUMA organization he created. Bold, creative and
driven by limitless curiosity, he always forged his own path, whether
searching for historic wrecks or writing new stories. 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.” — Dirk Cussler, son of Clive Cussler and author

“Through his novels, Clive Cussler
introduced Doxa to readers around the world, with the SUB constantly
present on Dirk Pitt’s wrist. As we mark what would have been his 95th
birthday, we are returning to the watch that began the SUB story — the
SUB 300 — reinterpreted here in Grade 5 titanium. 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. We are deeply grateful to the Cussler family for the
extraordinary friendship and trust they continue to share with Doxa.” — Jan Edöcs, CEO of Doxa

the secrets of maritime and naval history through the search for
historically significant lost vessels. Under Clive Cussler’s leadership,
a fearless team of maritime experts and NUMA volunteers undertook
daring expeditions to discover some of history’s most important
shipwrecks. Together, they explored more than sixty vessels lost to
the depths, each carrying stories waiting to be revealed. Their most

survivors following the sinking of the Titanic. NUMA returns all
recovered artifacts to national and federal authorities or donates them to museums and universities. Ready to experience the thrill of discovery?------------------------------
