When we published the first part of this exploration into 1,000m-rated dive watches, the response was immediate and enthusiastic. That didn’t surprise me. Watches capable of surviving a kilometer beneath the surface occupy a fascinating niche. They go well beyond everyday practicality and venture into the realm of over-engineering, professional utility, and, often, obsession. These are watches that don’t merely suggest adventure — they’re built for it.
In this follow-up, I wanted to expand the conversation by introducing five more watches that approach the 1,000m challenge from very different angles. The first article got a lot of reactions from our readers, who rightly pointed out some excellent examples. I thought it was only fair that we showcase some of the watches that I didn’t feature in the first story. Some lean heavily on heritage, others on brute functionality, and a few attempt to balance extreme capability with everyday wearability. As before, this isn’t about declaring a single “winner.” Instead, it’s about helping you understand which type of deep diver aligns best with your tastes, wrist, and philosophy as a watch enthusiast/collector.
Doxa Sub 300T
If you care about dive-watch history, the Sub 300T from Doxa needs no real introduction. This is a watch that earned its stripes on the wrists of professional divers long before “heritage” became a marketing buzzword. The modern Sub 300T stays remarkably faithful to the original Conquistador, both in spirit and in execution.
The C-shaped case is instantly recognizable, and while the 42.5mm diameter and 13.65mm thickness look substantial on paper, the short 44.5mm lug-to-lug and curved profile help it sit surprisingly well on the wrist. The signature no-decompression bezel remains one of the most purpose-built timing tools ever fitted to a mechanical watch, even if most of us will never rely on it for its original function. What makes the Doxa Sub 300T especially compelling in this segment is that it doesn’t feel like a luxury reinterpretation of a tool watch. It still feels like a tool. The finishing is functional rather than precious, the legibility is excellent, and the overall aesthetic is unapologetically utilitarian. For collectors who value authenticity and historical continuity, this is one of the most honest 1,000m-rated — actually, 1,200m-rated — dive watches you can buy today.
Rolex Sea-Dweller ref. 16600
The Rolex Sea-Dweller 16600 occupies a very particular place in the dive-watch landscape. It lacks the vintage charm of early Submariners and the modern spectacle of today’s oversized professional models. And that is precisely its appeal. This reference represents a moment when Rolex had refined the Sea-Dweller concept to near perfection. With its 40mm case, aluminum bezel insert, drilled lugs (depending on model year), and restrained dial layout, the 16600 feels purposeful without being flashy. The helium escape valve is there because it needs to be, not because it adds visual drama. Like the Doxa Sub 300T, the Sea-Dweller is rated to more than 1,000 meters, but it doesn’t seem overly chunky.
What continues to impress me about the 16600 is how wearable it is despite its depth rating. It slips under a cuff more easily than you might expect and never feels like it’s trying to prove a point. This is a watch designed for professional saturation diving, yet it transitions effortlessly into everyday life. For those who want a 1,000m(+)-rated dive watch that delivers maximum capability with minimum fuss, and for people who appreciate Rolex engineering but not the modern hype, the Sea-Dweller 16600 remains one of the smartest choices in the category.
Citizen Promaster Eco-Drive Professional Diver 1000m
Citizen’s Promaster 1000m diver is one of the most refreshingly honest watches in this entire segment. It makes zero attempts to charm you with vintage cues or luxury finishing. Instead, it focuses relentlessly on doing its job as well as possible. The chunky case construction, massive crown guards, and deeply recessed crystal all communicate the same message: this watch is built to survive. The use of Eco-Drive technology means you never have to worry about battery changes or winding, which, in a true professional context, is a genuine advantage.

On the wrist, this 52.5mm titanium Promaster is undeniably large and industrial. This is not a watch you choose for subtlety. However, it wears its bulk with a sense of purpose that makes it feel justified rather than excessive. Every design choice serves a function, from the aggressive bezel to the oversized hands and markers. For collectors who prioritize practicality, reliability, and value above all else, the Citizen Promaster Eco-Drive Professional Diver 1000m is difficult to fault. It may not have the romance of a Swiss mechanical movement, but as a modern tool watch, it is absolutely convincing.
Oris Aquis Pro 1000m
Oris has steadily built a reputation for producing serious dive watches that don’t feel overly niche, and the Aquis Pro 1000m is a perfect example of that philosophy taken to its extreme. At first glance, this is a substantial watch. The case is large, the bezel is bold, and the overall presence is unmistakably modern. But Oris has clearly put a great deal of thought into wearability. The integrated strap, refined case shaping, and surprisingly balanced proportions help prevent this 49.5mm Aquis Pro from feeling unwieldy.
One of the standout features is the bezel-locking system, which adds a layer of security without compromising usability. Combined with excellent lume and a highly legible dial, the Aquis Pro feels like a watch designed not just for depth but also for clarity and confidence in challenging conditions. What sets this watch apart is its ability to bridge worlds. It’s a legitimate professional diver, but it also works as a daily watch for someone who enjoys a contemporary aesthetic. If you want modern design, strong technical credentials, and a brand with a clear identity, the Aquis Pro 1000m deserves serious consideration.
Mühle Glashütte S.A.R. Rescue-Timer
The S.A.R. Rescue-Timer from Mühle Glashütte may be the most purpose-driven watch in this entire lineup. Designed in collaboration with German maritime search and rescue services, it is a watch created for professionals whose lives depend on reliable equipment. Everything about the S.A.R. Rescue-Timer prioritizes legibility and robustness. The dial is exceptionally clear, the hands are bold, and the lume is among the best you’ll find. The case construction is solid without being excessive, and all in all, it is an impressive design.
Unlike many dive watches that aspire to professional status, this one actually lives it. There is a sense of restraint in the design that speaks volumes. Nothing is superfluous, nothing is ornamental, and nothing distracts from its core mission. For collectors who appreciate functional design and real-world credibility, the S.A.R. Rescue-Timer offers something genuinely different. Mühle Glashütte may not carry the same name recognition as some competitors, but it more than compensates with authenticity.
Final thoughts
Exploring the world of 1,000m-rated dive watches is as much about philosophy as it is about specifications. Each of these watches represents a different answer to the same question: how do you build something capable of surviving extreme conditions? Whether you’re drawn to the historical significance of the Sub 300T, the understated excellence of the Sea-Dweller, the uncompromising functionality of the Promaster 1000m, the modern versatility of the Aquis Pro 1000m, or the professional focus of the S.A.R. Rescue-Timer, there is no wrong choice here, only different design priorities.
Ultimately, the right 1,000m-rated dive watch is the one that resonates with you, not just on paper but also on the wrist. And that, perhaps, is the most important specification of all. But what would you choose, Fratelli? I look forward to reading your suggestions in the comments!
