Bold claim: the Doxa SUB 750T proves that a big diver can wear comfortably, not just overwhelm your wrist. But here’s where it gets controversial: size alone isn’t the whole story—the way a watch wears matters just as much as its specs.

Hands-On The Doxa SUB 750T – A Large Watch That Actually Wears Well
The SUB 750T presents a substantial wrist presence and strong specifications, yet it delivers wearability that makes it one of the more engaging vintage-inspired divers you can buy today.
Last year, Doxa rolled out a new SUB 750T “Clive Cussler” model and soon after expanded the line with more variations in the brand’s signature hues. With updated specs, fans reacted in different ways: some impressed by the enhancements, while others dismissed it because it looks so similar to the iconic SUB 300, SUB 300T, and even the SUB 1500T. The new stainless steel case measures 45mm in diameter with a 47mm lug-to-lug span, noticeably larger than the 42.5mm by 45mm SUB 300. Yet the SUB 750T takes a 23-year-old concept and thin(-ner) it down, making it more comfortable on the wrist.
If you follow my notes rather than just glancing at the pictures, you’ll know I’m increasingly embracing oversized watches, thanks to my tall frame (6'7"/2 meters). Big Pilots, Radiomirs—these styles are growing on me. There’s a difference between “big” and “wearable.”
The SUB 750T captures much of what I admire about the SUB 300, but with more impact. It left me wondering whether it could be the better fit for me. Among the eight colorways released, I gravitated toward the orange “Professional” and the blue “Caribbean” for the shoot.
The full color lineup is available online, but the two hues shown here (plus the silver “Searambler” and black “Sharkhunter”) are likely to be the most popular choices. The dial design, with its sector-style layout, raised indices printed in black or white, bold hands, and steel dive bezel with a flat outer bezel edge that hints at a “no-deco” look, aligns with what many people expect from Doxa.
Yet the real highlight is the watch’s thickness, or rather, its slimness. The original 2002 launch of this design sat around 14mm thick. A quick comparison shows the SUB 750T (on the bottom) against Doxa’s robust SUB 1500T. Both share the same diameter and lug-to-lug length, but the SUB 750T comes in at just 11.95mm thick, while the 1500T sits at 16.25mm. By shaving around 2mm off the profile, Doxa achieves a sweet spot between bold styling and a thinner, more comfortable silhouette.
Pricing sits just under $2,800 on a bracelet, which many will view as solid value, though some may feel it’s a touch steep—echoing a broader trend in today’s market. And as a rule of thumb, diving watches typically shine on a bracelet, even if you’ll wear it primarily on other straps.
While I appreciate the idea of pairing the watch with a mesh bracelet (as James did), Doxa’s own bracelet—featuring a deployant clasp and a ratcheting wetsuit extension—offers ample comfort. For an additional $440, you can opt for a rubber strap with its own deployant. The only caveat: the lug width is 21mm, which means a broader selection of NATO or aftermarket options may require a full strap refresh.
On my 7.25" wrist, the SUB 750T feels like a natural upgrade over the SUB 300. The extra 2.5mm in width and 2mm in lug-to-lug length fill the wrist nicely, and at a thickness of roughly 0.05mm more than the Tudor Black Bay 58 I’ve worn for years, it reads as substantial without tipping into the oversized realm some watches inhabit.
From a technical standpoint, Doxa does a decent job listing measurements, but movement details deserve more clarity on their site. The watch houses a Sellita SW300 automatic movement, with some decoration by the brand, though you won’t see it through the caseback (which is engraved). A 56-hour power reserve and a 4Hz beat rate are respectable, yet the movement isn’t COSC-certified. In terms of value, you can find a similar, COSC-certified movement in a Formex Reef diver at a comparable price point.
Water resistance is generous at 750 meters, which draws attention more for its wow factor than practical needs. In real-world terms, most divers won’t use that depth, and even the deepest dives remain more about the watch’s presence than necessity. Compared to icons like the Rolex Deepsea, the Doxa achieves an impressive feat: sub-12mm thickness in a true dive watch. And at a price roughly $100 less than the SUB 300, it could be the option many buyers have been waiting for.
What this all adds up to is a watch that offers the charm of Doxa’s dive heritage in a slimmer package, with the option to wear it across a variety of wrist sizes and styles. It’s big, yes, but it doesn’t overwhelm. If you’re in the market for a bold, vintage-inspired diver that wears comfortably and wears its history proudly, the SUB 750T deserves strong consideration.
