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 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.
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.
