Although the most current form of the Longines Hydroconquest has only been around since March of this year, it comes up in a lot of conversations. Since its release, it has found considerable relevance with the value-focused audience, managing to strike a balance that is becoming increasingly rare – strong enthusiast value from a major brand at a competitive sub-luxury price point. In a space that used to be dominated by Omega (and more recently, Tudor), Longines has stepped up with an offering that checks a lot of boxes, including the fact that this new and nicely proportioned diver rocks a price tag that feels more 2016 than 2026.
Launched in 2007 as a dive-themed spin on the brand’s longstanding Conquest line, the Hydroconquest has had a handful of generations that progressively refined what started as a quirky diver with oversized numerals, chiseled crown guards, and a characterful hour hand with a diamond-shaped lume plot. Until recently, with the launch of the latest generation, that was the known format of the Hydroconquest. With modern positioning, it was just unconventional enough to stand out among its peers, and the brand’s alignment with Swatch allowed for reliable movements, attractive price points, and the chance of local retail availability.
An example of a 2018 Hydroconquest in 41mm offered as a US market LE.
Then, earlier this year, Longines launched this latest iteration in 42mm and, yes, 39mm. The watch you see here is the 39mm example, and its steel case measures just 11.7mm thick and 48.1mm lug-to-lug, making it very nicely proportioned. In addition to the attractive sizing, the Hydroconquest is water-resistant to 300 meters, has an automatic Longines L888.5 movement with a date, 72 hours of power reserve, and a silicon balance spring. At the entry price, the watch comes on a slim steel bracelet with tool-free micro-adjustment built into the clasp.
Spec-wise, though, little is new, as this was not the first time that Longines had offered a Hydroconquest in 39mm sizing. What is new, and managed to bring the model a new element of enthusiast relevance, was an evolution of its design that omitted much of the previous model’s characterful styling elements. Gone are the oversized cardinal numerals, so too the bold crown guards. The outcome, with a white date at 3, a shiny ceramic bezel, and a mix of round and rectangular markers, is a more subtle styling that offers broader appeal and feels like an obvious nod to the modern Rolex Submariner, especially when it comes to the bezel and the case shape.
So you have Longines quality, solid specs, two popular sizes, and some deeply conventional good looks. Add to that an array of colorways (which we will get into) and a price starting at $2,200 USD, and you have a recipe sure to turn heads in the enthusiast space. After a friend picked one up and couldn’t stop talking about it, I figured it was worth a proper hands-on.
In a rare turn, I may actually not need that many words to effectively translate the experience of the Hydroconquest into the core of this article. The sizing is excellent; the 120-click bezel is crisp and well-executed; the movement suits its application; and the dial design (while certainly not uncommon) is elegant, effective, and feels more upscale than I expected based on my previous experiences with the Hydroconquest.
The solid steel bracelet is a highlight, especially with its fully-brushed finish. It’s thin and drapes nicely en route to the fold-over clasp that includes a sliding push-button microadjust. Oh, and with the included half links, sizing is pretty simple. Once sized, the whole package is slim, comfortable, feels very high quality, and wears very well on my 7-inch wrist.
While the specific reference I borrowed for this story comes with a dark blue dial and bezel, the 2026 Hydroconquest comes in a variety of colorways, including black, green, back with a grey bezel, black with a bright blue bezel, a Longines boutique-only edition with an ice-blue dial and dark blue bezel, and an edition for the 2026 Commonwealth Games with a teal gradient dial and black bezel with teal accents. For my money, the dark blue version feels most Longines, but the black/grey certainly ranks at the top of my picks from the current offerings. If you want to mix things up further, Longines also offers a steel mesh bracelet for the 39mm Hydroconquest, though it does bump the price up $200 to $2,400. You can see more of that bracelet in TanTan’s original introduction story from March of this past year.
For those growing weary of my praise, I can pick a few nits. First, the two-color lume offers only mediocre performance, especially if you’re used to a Seiko or Citizen. Second, the bracelet uses split pins, which are a bit of a pain when sizing. I always like to see single-sided screws in use, especially once we’re well over the $1,000 ceiling. Neither of these elements would be a dealbreaker for me, but both are worth mentioning.
Other than that, the only other issue derived from my time with the Hydroconquest is its design similarity to that of the Rolex Submariner. This may be a plus for some, or a dealbreaker for others. The Submariner is perhaps the most influential sports watch design of all time, and elements of that design have provided inspiration to literally countless other watches, so this choice isn’t exactly uncommon, but I think it will be divisive among the intended audience (myself included).
But if the design language is a plus for you, you’re in luck, as this is simply an excellent watch. In the strata of watches I keep in a mental list for quick recommendation, this will certainly hold the slot anywhere near the $2,000 price point.
Speaking of pricing, let’s take a moment to consider where the 39mm Hydroconquest sits in the wider range of offerings for a steel dive watch, on a bracelet, and with a movement with ~70 hours of power reserve, all for around $2,200. From my perspective, there isn’t much that doesn’t represent a very different sort of watch or from a very different sort of brand. Consider the Doxa Sub 200T at $1790, the Rado Captain Cook 39mm at $2,650. Longines has hit a sweet spot in terms of pricing, and it becomes even more obvious when you consider the beloved Tudor Black Bay 58 starts at $5350 and Longines’ own Legend Diver 39mm is $3,850.
Closer in modernity and price to the Hydroconquest would be the Oris Aquis Date, which is 36.5mm wide and retails for $2,800. That said, the movement specs are lower, the watch is a good bit smaller, and you get a max of a 3-year warranty, so it’s not a strong 1:1 but does serve to underline the positioning of the Longines.
If you have a tighter budget, you’re either considering some of the more entry-level Swatch brands like Mido or Certina, or you’re looking at Seiko, Citizen, or going for a microbrand – all of which are great options. But for a small premium over some of those offerings, I think the Longines is much more directly comparable to watches that cost a good bit more, not less. In addition, Longines is a brand you can commonly find in local metropolitan retail (always nice to see and try on a new watch first), and, like Tudor, Longines has a 5-year warranty.
So, while not rewriting any of the script, Longines has made a compelling, well-priced, and easy-wearing diver that doesn’t skimp on specs or features. To be completely transparent, I didn’t pay much attention to this watch when it came out simply because I didn’t find it all that exciting. Then, a close friend finished a long hunt for a daily diver, and after trying many of my watches (among several others from many of the brands mentioned above), he picked up the black-dial/grey-bezel 39mm Hydroconquest and just refused to shut up about it.
After spending a week with the 39mm Hydroconquest, I get why he was so pumped up about it. While I would personally prefer something a bit more exciting (I remain a huge fan of my Hodinkee Spirit Zulu LE, for example), that doesn’t diminish the value offered by this latest evolution of the Hydroconquest.
And so I joined the choir. If you’ve been curious as to all the fuss about this new Longines diver, it’s definitely worth trying one on for yourself.
