Review: Longines’ Conquest 38mm Is the Affordable Aqua Terra Alternative You’ve Been Waiting For

Few brands in watchmaking can claim a resume quite like Longines. Founded in 1832 by Auguste Agassiz in Saint-Imier, Switzerland, the brand takes its name from the riverside plot of land (“Les Longines,” or “long meadows”) where it built its factory in 1867, a facility it still occupies to this day. And that winged hourglass logo you see on the dial? It’s recognized as one of the oldest active registered trademarks in the world.

Longines spent the following century racking up plenty of horological firsts, from pioneering pocket chronographs in the late 1800s to timing Charles Lindbergh’s transatlantic flight in 1927. But today, we’re focused on one of the most storied names in the brand’s catalog: the Conquest. Introduced in 1954, the Conquest holds the distinction of being the first Longines collection to have its name protected by the Swiss Federal Intellectual Property Office, and it’s served as the brand’s do-everything sports watch ever since.

When Longines rebooted the Conquest in 2023, it was nearly a complete overhaul. Gone were the previous generation’s polarizing oversized Arabic numerals at 12 and 6, along with the dive-watch levels of water resistance that muddied the model’s identity. In its place was now a cleaner, more refined take on the everyday sports watch. Of course, the reception was overwhelmingly positive, but there was still one glaring exception: the collection first launched in both a 41mm and 34mm, leaving a gaping hole right where most enthusiasts wanted it.

The comment sections spoke, Longines listened, and the Conquest 38mm arrived shortly after, quickly earning nicknames like “the affordable Aqua Terra” and “the Datejust for the masses” from the community. We’ve been wearing this watch on and off over the years, and since it’s become a staple in our own rotation, we thought it earned itself its own review to see if the hype holds up.

At A Glance

First Impressions

Pulling the Conquest 38mm out of the box, the first thing that strikes you is just how much more expensive it looks than its $2,400 price tag suggests. The sunray black dial, the interplay of brushed and polished steel, and the sheer density of the head and bracelet. It really does feel like a watch from the tier above.

Longines offers the 38mm in five sunray dial options: black, silver, blue, green, and a champagne that replaced the outgoing 41mm’s chocolate brown. The black, blue, and green variants can also be had on color-matched rubber straps, though it’s the bracelet that steals the show here (more on that later).

And that’s really the story here. The internet loves to frame this watch as a budget Rolex Datejust, but spend a few minutes with it and the comparison that keeps surfacing (both in our minds and all over the comment sections) is the Omega Aqua Terra. The polished bezel, the applied indexes, the sporty-yet-dressy character, and the everyday versatility all point squarely in that direction. And plenty of owners have told us they cross-shopped the two directly before landing on the Longines at a third of the price.

Of course, the $2,400 price bracket is contested territory, sandwiched between cheaper value monsters like the Tissot PRX Powermatic 80 below and entry-luxury heavyweights above. But we think the Conquest makes a really compelling case across the board.

The Case

On paper, the Conquest measures 38mm across, 46.8mm lug-to-lug, and 10.9mm thick, and in practice, those numbers translate beautifully. It’s substantial enough to hold real presence, slim enough to disappear under a cuff, and the proportions sat right at home on our wearer’s 6.75″ wrist shown here. If anything, the watch wears a touch larger than 38mm thanks to the slim, fixed bezel giving the dial nearly all of the real estate.

The finishing is where Longines really shows off its value chops. The tops of the lugs and case are vertically brushed, while the bezel and case sides are polished to a mirror shine. It’s a combination that catches light wonderfully but will also pick up desk-diving scratches faster than an all-brushed tool watch.

The streamlined crown guards are a massive improvement over the aggressive, industrial-looking guards of the previous-generation Conquest, flanking a signed screw-down crown that helps deliver a healthy 100 meters of water resistance.

Flip the watch over and you’ll find a screw-down exhibition caseback with sapphire crystal, proudly displaying the L888.5 caliber within, along with “Magnetic Resistant” engraved around the perimeter.

The Dial

Seeing that we’re suckers for a well done black dial, it’s no surprise that the sunray black dial is easily one of our favorite executions in the lineup. In dim lighting it reads as a stealthy, monochromatic black, but catch it in direct sun and it comes alive with charcoal and gunmetal tones radiating from the center.

Adding to the depth is a concentrically finished inner ring running just inside the minute track, a subtle sector-style detail pulled from 1950s Conquest models that gives the dial a layered, almost architectural quality that you just don’t see too often on watches at this price point.

The applied, trapezoidal hour markers are beveled on every edge and polished to match the dauphine-style handset, and both catch light beautifully against the dark backdrop. Up at 12, the applied winged hourglass logo balances the spacious “Conquest Automatic” text above 6, and Longines deserves some credit for keeping the dial refreshingly free of clutter.

At 6 o’clock sits a date window, and on this black variant the date disc is color-matched to the dial, a detail we’re thrilled about, though we’d note the green and champagne variants make do with white discs, and it’s something you’ll see owners complaining about across the forums.

Up top is a sapphire crystal with several layers of anti-reflective coating on both sides, and legibility is excellent day-to-day. Unfortunately, nighttime is a bit of a different story.

Longines applies Swiss Super-LumiNova to the hands, the larger cardinal markers, and small square plots beside the remaining indexes, but the glow is faint and fades a bit too quickly. It’s serviceable for a midnight glance, but if lume is a priority, this definitely is not the watch for you. It’s the most consistent critique from the community, and after our time with the watch, we can’t argue with it.

The Movement

Under that exhibition caseback beats the caliber L888.5, and it’s arguably the single biggest reason to buy this watch. The movement is based on the ETA A31.L11, itself built on the architecture of the slim, workhorse ETA 2892-A2. And thanks to Longines’ privileged position within the Swatch Group, it’s a caliber you won’t find in watches from competing brands at this price.

The movement beats at a slightly slower 25,200 vibrations per hour (3.5Hz), which, combined with a larger mainspring barrel, stretches the power reserve to a full 72 hours.

The L888.5’s 3.5Hz rate keeps a noticeably smoother seconds sweep while still clearing three full days off the wrist. The 2892 architecture is also the slimmer, more premium base that ETA reserves for its upmarket clients. And it’s also a big part of why the Conquest wears under 11mm thick.

Even more impressive is the monocrystalline silicon balance spring, a technology that until recently was reserved for watches costing multiples of this price. Silicon is impervious to magnetism, and it’s the reason that caseback proudly reads “Magnetic Resistant.” Considering we’re constantly setting our watches down next to laptops, phones, and magnetic bag closures, it’s a nice piece of added convenience.

The L888.5 isn’t COSC certified, but in real world use, it hardly seems to matter. Owner reports consistently cite accuracy within a few seconds per day, with some examples running within chronometer spec over months of ownership, not to mention hand-winding the crown is remarkably smooth.

Rounding things out are 21 jewels, hacking seconds, and tidy (if modest) finishing with a signed rotor. For $2,400, we’re struggling to name a better-equipped three-hander.

The Bracelet

The Conquest comes fitted on a stainless steel H-link bracelet that continues the case’s brushed-and-polished finishing, with polished center links adding just enough flash. It’s supple, articulates well, and wears comfortably through a full day.

There are, however, a few quirks worth flagging. The lug width is an oddball 19mm, which limits your aftermarket strap options a bit. The spring bars also aren’t quick-release, so you’ll need a tool for swaps.

The bracelet tapers down to a butterfly clasp with a push-button release, which keeps the underside sleek, but it offers no on-the-fly micro-adjustment. Longines includes half links on either side to dial in your fit, and we found a comfortable setting without much hassle.

Still, on sweltering summer days, we would’ve loved a quick way to let the bracelet out. It’s the number one request from owners, and we’d echo it.

Final Thoughts

So, the question we always ask ourselves at the end of a review: is the Longines Conquest 38mm worth it?

Let’s look at the landscape. The closest cross-shop lives in-house: the Longines Spirit 37 ($2,850) runs the same caliber family with COSC certification in a full-on pilot’s package.

But the real head-to-head would probably be Tudor’s Black Bay One 36 (around $4,700), which counters with a COSC-certified manufacture caliber, a 70-hour reserve, and the on-the-fly adjustable clasp the Conquest lacks. It’s definitely a phenomenal watch, but it also costs nearly twice as much.

Up at the aspirational end, the Omega Aqua Terra 38mm (around $7,100) and Rolex Datejust (north of $8,000) offer superior finishing, but you’re paying nearly triple the price. The Conquest slots into that ladder beautifully. It feels like a legitimate taste of the entry-luxury experience but without the entry-luxury price tag.

Sure, the watch has some flaws. The lume is forgettable, the 19mm lug width gives you less strap options, and the clasp deserves micro-adjustment. But none of those come close to sinking what is otherwise one of the most complete everyday watches we’ve handled at this price.

We think it’s a fantastic watch for the enthusiast graduating to their first serious Swiss automatic, the one-watch collector who needs a versatile everyday piece, or frankly, anyone who’s been eyeing an Aqua Terra but can’t wrap their head around the price.

And to be clear, the Conquest 38mm isn’t pretending to be a Rolex or an Omega. And it’s proof that Longines doesn’t need to.

Does the Conquest 38mm live up to the “affordable Aqua Terra” hype, or is there a better everyday watch at the $2,500 price point we should be looking at? Let us know in the comments below.
