Which Vintage-Inspired Dive Watch Gets It Right: Squale Sub 37 Legend vs. Baltic Aquascaphe?

Vintage-inspired dive watches are everywhere now, which means most of them are doing an impression rather than telling the truth. You know the type. Lume the color of weak tea, a dial baked until it looks like it spent a decade in a glovebox, and not a shred of actual history underneath any of it. After nearly a decade of reviewing watches and spending real wrist time with both the Squale Sub 37 Legend and the Baltic Aquascaphe, what makes these two worth putting head-to-head is that neither one is faking it in the lazy way. They both reach back toward mid-century diver design, but they get there from completely different starting points, and that difference is the whole reason a Squale Sub 37 Legend vs Baltic Aquascaphe comparison is more interesting than another round of “which one looks more old.”

The question we’re actually trying to settle isn’t which watch wears its nostalgia louder. It’s which one gets vintage right and “right” turns out to mean two very different things depending on which watch you’re holding. One of these has the bloodline, a brand whose identity has been tangled up with dive watches for decades, revisiting its own past with a steady hand. The other has no specific ancestor at all, yet somehow conjures the feeling of a watch you found in a drawer better than watches three times its price. We’ve enjoyed both in our hands-on reviews, but this comparison is about which approach earns the word “authentic,” and the answer is closer than the price gap between them would ever suggest.

Overview & Identity

The Squale Sub 37 Legend comes into this comparison with something most vintage-inspired divers can only cosplay: an actual lineage. In our hands-on review, what stood out was that Squale isn’t borrowing someone else’s heritage here. The brand’s identity has been wrapped up in dive watches for a very long time, and the Sub 37 Legend feels less like a nostalgia exercise and more like Squale revisiting one of its own earlier ideas through a modern lens. The old-radium-toned lume, the curved black bezel insert, and the double-domed sapphire all conspire to read like a much older watch, yet nothing about it feels fragile or precious. The trade-off is that this restraint can come across as understated, almost too quiet, if you were hoping for a watch that shows off.

The Baltic Aquascaphe sits at the other end of that idea entirely. Over the course of our testing, the thing that kept surfacing was that the Aquascaphe doesn’t trace back to a specific reference at all. It pays tribute to an entire era rather than continuing one model’s story, with a dial that nods toward vintage Tornek-Rayville more than any single ancestor. And yet it pulls off the trick anyway. It feels like an NOS diver you unearthed in a relative’s cigar box full of Navy memorabilia, which is a strange thing to say about a watch from a brand that only arrived in 2017. The catch is exactly that youth: there’s no real bloodline here, so the authenticity is something the watch evokes rather than something it inherits.

Dial & Wearability: Quiet Restraint vs Evocative Warmth

The Squale keeps the dial about as honest as a dive watch gets. The black dial is clean, highly legible, and free of anything fighting for attention, and the old-radium lume on the hands, indices, and bezel introduces the vintage note without sliding into faux-aged territory. We’ve gotten increasingly twitchy about aggressive vintage treatments over the years, and the Sub 37 Legend shows the kind of discipline that’s become rare. On the wrist, the headline number is 37mm, and plenty of collectors will make a snap judgment about that. They’d be missing the point. At roughly 38.5mm including the bezel, 45mm lug-to-lug, and a genuinely thin 11.2mm, it wears with far more presence than the diameter implies. It sits low, slides under a cuff without a second thought, and after a few days simply starts feeling correct. The Bonetto Cinturini rubber strap is one of the better ones we’ve handled, soft and comfortable straight out of the gate, though the 19mm lug width is uncommon enough that swapping straps becomes more of a hunt than it should be.

The Aquascaphe is the more theatrical of the two, and that’s a compliment. The hybrid “sandwich” dial cuts through its surface to reveal a fully lumed layer underneath, which turns what could have been a flat time-only layout into something with real depth. The whole thing is rendered in a gilt/artificial-patina tone that warms the dial without tipping into cheese, paired with two crisp pencil hands and a lollipop seconds hand that stretches all the way to the chapter ring. Text is minimal, the font carries that Tornek-Rayville flavor, and the matte textured surface shifts character depending on the light hitting it. At 39mm across the bezel, 38mm at the case, 47mm lug-to-lug, and 12mm thick, it wears like the mid-century skin diver it’s channeling. The beads-of-rice bracelet does a lot of the comfort work (polished beads, brushed everywhere else, conforming and tapered) and the quick-release spring bars mean changing to the optional Tropic strap takes seconds.

• The Squale Sub 37 Legend delivers the more restrained, immediately legible dial, and its slim 11.2mm profile makes 37mm wear with surprising confidence.
• The Baltic Aquascaphe brings the more evocative dial of the two, with a sandwich layout and gilt warmth that does the most to summon a genuine found-vintage feeling.

Build Quality & Technical Approach

Both watches are chasing the same goal (a vintage diver you can actually live with rather than baby) but the Squale Sub 37 Legend and Baltic Aquascaphe take noticeably different roads to get there.

Movements and Ownership Experience

The Squale runs the Sellita SW200-1, which by now is familiar territory for most enthusiasts, and that familiarity is the point. In our review the movement simply disappeared into the background. The accuracy stayed consistent, operation was dependable, and the crown action was smooth with none of the grittiness that sometimes shows up around this architecture. That might sound like faint praise, but reliability is the feature here. There’s no exotic mechanical party trick waiting to become an expensive problem at service time, just a known quantity getting on with the job.

The Aquascaphe takes the time-only route with the Miyota 9039, a thinner version of the 9015, and the choice fits the watch’s stripped-down honesty. With two positions, stop and go, you avoid the “phantom” click you get fussing with date-equipped movements, which feels appropriate for a watch this uncomplicated. It runs at 28,800 vph with a 42-hour power reserve, and Baltic regulates and tests each one with an in-house watchmaker in France, near Besançon — a nice touch at this price. Performance on our sample was top-notch, and the undecorated movement suits a watch that was never trying to show you its mechanical homework.

Case Construction & Finishing

The Squale leans into polish where you might expect a tool watch to stay matte, and it works in its favor. The polished case catches light in a way that adds a little personality without undercutting the dive-watch roots, and the thinness is the genuine star. Modern divers too often feel like a contest to see how much steel can be stacked between wrist and dial, and the Sub 37 Legend pointedly refuses to play. It stays balanced through the day and never reads as a design statement so much as a watch that got its proportions right.

The Aquascaphe goes the other way, keeping polished surfaces to a minimum and putting real thought into the textured crown. The case finishing is fluid in a way that feels older than the watch is, and Baltic included drilled lugs even though the bracelet already rides on quick-release spring bars, a generosity you rarely see at this end of the market. The result is a robust, well-balanced case with a screw-down crown and screw-down caseback that feels like it was built by people who actually like watches rather than people optimizing a spreadsheet.

Crystals and Bezels

The Squale’s double-domed sapphire captures much of the visual charm of vintage acrylic while keeping the durability you’d want from a modern watch at this price. The anti-reflective treatment does throw a pronounced blue hue at certain angles, which is the one detail likely to split the room — some collectors love it, some don’t, and we found it noticeable without becoming distracting. The bezel action is smooth with positive engagement and a small amount of play if you go looking for it, though it never intrudes during normal wear.

The Aquascaphe also runs a double-domed sapphire crystal, and it pairs that with a lumed sapphire bezel insert, a feature that punches above the watch’s price and ties the bezel visually into the dial’s glow. It’s a clean, period-appropriate execution that keeps the vintage silhouette intact without resorting to acrylic and the scratches that come with it.

Water Resistance & Lume

The Squale backs its compact case with 300 meters of water resistance, helped along by the screw-down crown and solid caseback, which is more than almost anyone will ever ask of it. The old-radium-toned lume reads as vintage aesthetics first, but visibility after dark stayed perfectly adequate throughout our time with it — nothing extraordinary, nothing disappointing, just exactly what we expected. One small detail we kept coming back to is the signed crown with the von Büren logo, the kind of touch that signals attention was paid to the whole package rather than just the headline specs.

The Aquascaphe comes in at 200 meters, which is plenty for a watch that’s far more likely to see a dinner table than a dive boat, but it’s worth noting it trails the Squale’s 300m on paper. Where it claws ground back is the lume itself: the sandwich dial hides a fully lumed surface beneath the cut-outs, rendered in Swiss Super-LumiNova and warmed to match the gilt tone. That layered glow is a big part of why the dial has the depth it does, and it’s a more interesting lume story than the spec sheet alone would tell you.

• The Squale Sub 37 Legend takes the more confident technical route, pairing a proven Sellita SW200-1 with 300m of water resistance, a double-domed sapphire, and restrained old-radium lume.
• The Baltic Aquascaphe answers with time-only Miyota simplicity, 200m water resistance, a lumed sapphire bezel, and a sandwich dial whose hidden lume layer carries more visual depth than its rating suggests.

Cost and Long-Term Value

At $1,750, the Squale Sub 37 Legend asks a real number, and some collectors will hesitate at it the same way we initially did. After living with the watch, though, that figure settled into feeling fair. The execution is strong from the dial to the strap, and at no point did it give the impression that corners had been cut to hit a price. More to the point, the Sub 37 Legend occupies a space very few watches do. It captures the appeal of early Squale design without making the owner navigate vintage-market uncertainty, aging components, or any of the compromises that ride along with genuinely old dive watches. You’re paying for the heritage and the modern reliability, and for the right buyer that combination is the whole argument.

The Baltic Aquascaphe lives in a completely different value universe, with pricing that started around €600 at the time of our review (worth verifying against current Baltic pricing, as this watch and its lineup have evolved considerably since). Even allowing for changes since, the Aquascaphe’s case is built on delivering an outsized amount of watch (sandwich dial, beads-of-rice bracelet, lumed sapphire bezel, in-house regulation) for money that makes the spec list look like a typo. Add the breadth of dial options and the GMT and Dual-Crown variants that followed, and it’s a brand clearly run by people who’d rather give you more watch than more margin. If your definition of “getting vintage right” includes the price feeling vintage too, this is the one that wins outright.

Final Thoughts: Which Vintage Diver Gets It Right?

The Squale Sub 37 Legend is the one we’d point to if the question is specifically about getting vintage right in the fullest sense of the word. It has the lineage to back the design, the restraint to keep that design from curdling into costume, and the modern execution to make the whole thing something you can wear without ceremony. The compact case and slim profile pull it all together into a watch that feels fully resolved rather than assembled from a checklist of enthusiast wants. The reservations are real in it costs meaningfully more than the Baltic, the AR’s blue cast won’t be for everyone, and the 19mm lugs complicate strap life. But on the core question of authenticity earned rather than evoked, it has an advantage the Baltic structurally can’t match.

The Baltic Aquascaphe makes this far closer than the price gap has any right to allow. It has no specific ancestor, no decades-deep dive-watch bloodline, and a water-resistance figure that trails its rival — and it still summons the feeling of a found-vintage diver more vividly than watches several times its price. The sandwich dial, the gilt warmth, and that beads-of-rice bracelet add up to genuine charm at a price that borders on unfair. If your version of “right” is about the emotional hit a vintage-inspired watch delivers per dollar, the Aquascaphe arguably takes it.

But the question was which one gets vintage right, and by a slim margin that comes down to the Squale Sub 37 Legend. The Baltic evokes the era brilliantly; the Squale actually belongs to it. When a brand revisits its own history with this much discipline, the authenticity stops being an aesthetic and starts being a fact and for this corner of the hobby, that’s the difference that decides it. It’s close, the Baltic remains the smarter buy on pure value, but if “getting vintage right” is the bar, the Squale clears it by a hair.
