DOXA Brings Grade 5 Titanium to the SUB 300 Clive Cussler Edition

DOXA’s latest Clive Cussler tribute is more than another literary nod.

The SUB 300 Ti5 moves the brand’s 1960s dive-watch shape into Grade 5 titanium for the first time in this historically minded line, while keeping the practical 300-metre personality that made the name stick.

Limited to 300 pieces, it also introduces a new dial construction that gives the watch a sharper, more technical character than the usual vintage-leaning formula.

At a glance

Grade 5 titanium reshapes the SUB 300

The SUB 300 has always been easy to recognise, with its broad cushion case, compact lug-to-lug feel and decompression bezel architecture.

Here, that silhouette is machined from Grade 5 titanium rather than stainless steel, giving the 42.5 mm by 45 mm case a lighter, more contemporary presence on the wrist.

Grade 5 titanium is an alloy of titanium, aluminium and vanadium, and it brings higher strength than commercially pure titanium alongside strong corrosion resistance and hypoallergenic comfort.

It’s also harder to work with than softer grades because it can’t simply be stamped into shape, so DOXA has used CNC machining to form the case.

The watch remains a proper dive instrument, with 300 metres of water resistance, a solid screw-in titanium caseback and a boxed sapphire crystal that nods to the profile of older Plexiglas-equipped models.

The unidirectional bezel keeps DOXA’s well-known dual-scale layout, pairing black timing minutes with orange depth markings across brushed and polished surfaces.

The dial and movement carry the Cussler story

The most visually important change is the new dual-plane sandwich dial, a first for DOXA.

Both dial layers are Grade 5 titanium, with a luminous lower layer carrying the minute track and a precision-cut upper plate creating clean openings for the indexes and date.

The result is a more dimensional display than a conventional printed dial, helped by a matte sandblasted grey finish and the contrast of glossy black hands.

DOXA keeps one decisive hit of colour through the oversized orange minute hand, a smart connection to the orange-dialled DOXA that Clive Cussler famously placed on Dirk Pitt’s wrist.

The date window at 3 o’clock carries a quieter tribute, with the numerals 15, 7 and 31 printed in orange to mark Cussler’s birth date of 15 July 1931.

Behind the solid caseback is the Sellita SW200-1 automatic calibre, certified by COSC as a chronometer after testing across five positions and three temperatures.

It runs at 28,800 vibrations per hour, uses 26 jewels and offers an approximate 38-hour power reserve.

The caseback bears the emblem of the National Underwater and Marine Agency, better known as NUMA, with a portion of proceeds going toward the non-profit organisation’s maritime preservation work.

Details & Specifications

The SUB 300 Ti5 Clive Cussler works because it doesn’t lean on nostalgia alone.

It gives collectors a lighter, sharper and technically stronger take on one of DOXA’s defining dive-watch shapes, while keeping the literary connection just discreet enough to feel personal rather than theatrical.
