Bold opening: AWatch that looks fearless yet wears like a dream—the Doxa SUB 750T proves size and wearability aren’t enemies. And this is where it gets controversial: does a big diver need to feel this comfortable on a daily basis, or is the chunky silhouette merely a visual statement? Now you’ll see why the 750T sits at a fascinating crossroads of presence and practicality.
The SUB 750T arrived on the scene with a splash, debuting in a special Clive Cussler edition and later expanding into a spectrum of colors that echo Doxa’s signature palette. Its 45mm diameter paired with a 47mm lug-to-lug span immediately signals a bold footprint, notably larger than the 42.5mm by 45mm SUB 300. Yet the 750T manages to feel surprisingly slender and comfortable on the wrist, thanks to a slimmer profile that refines the original idea from two decades ago.
If you’ve followed my writing, you know I’m gradually embracing oversized watches, especially on someone tall like me (6'7" / 2 meters). Big pilots, Radiomirs, you name it—I'm leaning into the idea that bigger can also be wearable. The key distinction is meaningful heft: big for impact, yes, but still comfortable enough to wear daily. The SUB 750T nails this balance, offering much of the SUB 300’s appeal with a stronger presence.
Color options are plentiful, and while I sampled a few, the orange “Professional” and blue “Caribbean” stood out for shoots. The full lineup spans eight hues (you can browse them online), but the most common picks tend to center on the two shown here, plus the silver “Searambler” and black “Sharkhunter.” The dials showcase a sector-style layout, raised indices in black or white, bold hands, and steel dive bezels with a restrained outer edge that evokes classic Doxa styling.
The real standout here is thickness. When the model first launched in 2002, it wore about 14mm of height. Compare the SUB 750T to Doxa’s burliest variant, the SUB 1500T: both share the same diameter and lug-to-lug, but the 750T clocks in at a mere 11.95mm thick, while the 1500T sits at 16.25mm. That 2mm drop matters. It tames visual bulk without sacrificing the watch’s robust character, achieving a pleasing harmony between bold design and a slender profile.
Pricing is a consideration, and at just under $2,800 on the bracelet, the SUB 750T presents solid value—though some might feel it’s a touch high for a non-COSC automatic. In today’s market, premium dive watches often run at or beyond this mark, so the value proposition hinges on the brand’s distinctive look and the watch’s wearability.
A bracelet-first approach remains wise. Doxa’s own bracelet with a deployant clasp and a ratcheting wetsuit extension is comfortable, and an additional $440 buys you a rubber strap with its own deployant. The one constraint for some buyers is lug width: 21mm, which means if you want to try a wider selection of straps, you might need a new set of NATO options or swap to the existing bracelet more often.
On my 7.25" wrist, the SUB 750T feels like a natural fit, likely more suitable than a SUB 300 for daily wear. The extra 2.5mm in width and 2mm in lug-to-lug, combined with a thickness nearly identical to the Tudor Black Bay 58, gives you a watch that looks substantial without tipping into comically oversized territory.
From a movement perspective, Doxa uses a Sellita SW300 automatic, decorated by the brand and housed behind a closed caseback with an engraved motif. The movement offers a 56-hour power reserve and a 4Hz beat rate, which are respectable but not exceptional in terms of precision certification. A COSC-certified alternative with similar specs is available in some competing models, such as certain Formex Reef configurations, which may appeal to buyers seeking formal accuracy guarantees.
Water resistance is listed at 750 meters, a depth well beyond everyday needs. In practice, such depth is more about the watch’s iconography—the drama of depth—than utility for most wearers. The Deepsea’s extreme ratings are fascinating feats of engineering; the SUB 750T’s sub-12mm thickness does its own kind of magic, proving you can build a highly capable diver without sacrificing elegance or wearability. And at a price point modestly beneath the SUB 300, it offers a compelling option for those seeking a bold, versatile dive watch.
Where this watch truly shines is in the balance between style and comfort. It foregrounds presence without overwhelming the wrist, making it a strong candidate for those who want a big watch that feels ready for everyday wear. If you’re shopping for a standout dive watch that doesn’t force you to compromise on wearability, the SUB 750T deserves serious consideration.
