When Doxa introduced its newest tribute to prolific author Clive Cussler in July 2025, fans of the legendary dive watch brand knew it had to be hinting at something more.

As cool and on-brand as the special edition dial and engraved caseback were, the most intriguing detail was the case height.

The new SUB 750T has a streamlined 12mm tall case.

When Doxa debuted the SUB 750T in 2002, the most water pressure-resistant addition to the SUB series had a 14mm thick case. Combined with the 45mm width and 47mm lug-to-lug, it was a real wrist eater.

At the time, a stainless steel watch case had to be huge to achieve 750m water resistance, but horological engineering has come a long way in the past two decades.

Doxa’s SUB 750T Clive Cussler edition buried the lead that the ultra-capable diver has shed two millimeters of case height.

Stainless steel DOXA Sub 750T automatic dive watch with a blue dial, orange minute hand, white hour and second hands, date window at 3 o'clock, and a stainless steel bracelet. The bezel features orange and black markings. — The SUB 705T is available on the brand’s signature beads-of-rice steel bracelet or a rubber strap.

Two millimeters might not sound like much, but it can be felt on the wrist when measuring a watch case. It means less weight and a smaller protrusion from the wrist to get snagged.

Less is more

Under most circumstances, case size is limited by the size of the movement and types of complications. Designers can make watches as big as they want, but can’t make them any smaller than those factors allow.

Dive watches are different because they deal with outside forces, specifically water and water pressure. Horological engineers must create a water-tight seal that can withstand the added atmospheric pressure of established depths.

As the crushing force of water pressure increases with depth, steel cases and crystal must be scaled up to maintain structural integrity. Which is why extreme dive watches are bulky, but Doxa has managed to trim the SUB 750T vertically while keeping the collection’s signature blueprint intact.

Doxa remains true to its flagship design, which debuted in 1967 with the SUB 300, regardless of size. From the 39mm SUB 200T up to the hardcore SUB 1500T, the same elliptical case, saw tooth non-decompression dive bezel and high-contrast hands are in place.

A kaleidoscope of divers

Doxa launches the regular production version of its svelte new SUB 750T with a robust collection that includes all eight of the brand’s nautical-themed dial colors.

Of course, the orange Professional is included, along with the dark blue Caribbean, yellow Divingstar, black Sharkhunter, steel Searambler, turquoise Aquamarine, the white Whitepearl and the newest addition, the green Sea Emerald.

Steel DOXA SUB 750T automatic wristwatch with a stainless steel bracelet, featuring a white dial, orange minute hand, black hour hand, black second hand, date window at 3 o'clock, and a black and orange bezel with depth markings in feet. — The regular production SUB 750T includes all eight standard dial colors.

The Sea Emerald and Searambler stand out with radial brushed textures, while the rest have flat glossy dials. Each watch is available on a rubber dive strap that matches the dial color, except for the steel Searambler, which uses black.

Another notable difference in color is that the Sharkhunter, Searambler, and Caribbean models use an orange minute hand, while the rest of the collection has uniform black hands. However, they all have the same Super-LumiNova and the printed hour markers on all three hands.

Doxa stuck with Sellita for the new SUB 750T’s movement, but this time, it is the caliber SW300 rather than the caliber SW200. The only performance difference is an increased power reserve of 56 hours.

The watch has a stainless steel case with a rotating bezel marked with orange and black numerals, a date window at 3 o'clock, and a black rubber strap. The dial also features the text "DOXA automatic," "SUB 750T sharkhunter," and "SWISS MADE. — The Sharkhunter, Searambler and Caribbean models use an orange minute hand.

This new regular production SUB 750T adds another layer of depth to the fan-favorite SUB series, offering a larger and more capable option. It has the same look and color options as its recently updated smaller family members.

It would have been nice to see a little something unique added to this ultra-capable SUB, but I suppose that’s what the limited edition Clive Cussler reference is for.
