Associating modern Jaeger-LeCoultre with anything but the Reverso is difficult considering how much time and effort the watchmaker’s watchmaker puts into telling its story, but it also comes as a detriment to some true gems in the JLC offering. This year has already brought us two examples of this – first, the unfortunately limited 36mm Master Control Classic in January, and quietly released during the Master Control Chronometer-dominated Watches & Wonders, the new Polaris Date in 40mm. In the entire JLC landscape, the Polaris is only second to the Rendez-Vous in terms of taking a back seat in favour of the brand’s “dress” and haute horlogerie focus, but this does mean that every once in a while, a real gem slips past. The new Polaris Date 40 isn’t an improvement just because of a reproportioned case, but its other subtle touches make it a more cohesive design that helped me realise this isn’t competing with other dive watches on the market, but is rather targeting the luxury sports watch sector more generally. Here’s why it’s made our list of best releases of 2026.
Small, but mostly welcome changes
Let’s run through those aforementioned changes first, shall we? Compared to the 42mm variant (that is going nowhere, by the way), the Polaris Date 40 drops down the diameter, lug-to-lug, and thickness, the latter going from 13.92mm to 12.9mm. On paper, this seems negligible, but when you consider that makes the 42mm Polaris thicker than a Seamaster 300M, a watch notorious for not being particularly slim, it makes a real difference. Achieving this was not the result of some major redesign, but rather subtle tweaks that reduce both actual and visual weight. For starters, the mid-case is a lot slimmer, allowing the lugs to curve down to meet the caseback which protrudes just slightly more, but disappears when on-wrist. The box-domed crystal is fantastic in carrying some of the vintage cues – appropriate given its design harks back to the 1968 Memovox Polaris – and does a great job of making it appear even slimmer, taking up some 2mm of the overall height.
This side view also allows us a look at the sharp transition in finishes between all the surfaces, as well as the dual crowns, the Polaris’ design signature. You’ll be surprised to know, just as I was when handling a Polaris for the first time, that neither of them screw down. You still get 200 metres of water-resistance, which would be plenty for any watch with intending to be a diver, but without that additional security that’s become expected, I can’t call this a dive watch – and to be fair to them, JLC doesn’t either.
While I’m certainly thankful that JLC decided to downsize it, my absolute favourite change in the Polaris 40 is the new dial layout. With a smaller case, the entire dial had shrink too, and the first omission is half-size index next to the date window. Sure, this means the watch technically doesn’t comply with the ISO-prescribed standard for a dive watch, but neither does a Rolex Sub Date, so who cares?
The Jaeger-LeCoultre branding and logo now sit inside the innermost dial circle, finally moved from the awkwardly-squeezed in text under the 12 o’clock index on the larger models. What’s more, the “automatique” text that used to nestle above the 6 just as awkwardly is gone completely – both fantastic choices by the JLC design team.
Speaking of things that don’t screw down, there’s the display caseback, which is a screw-on style. As long as it doesn’t affect thickness or water-resistance in a negative way, you won’t see me complaining. Another benefit from the reduced case is that the JLC calibre 899 no longer looks as tiny and deep inside the caseback. This is something that really bothered me with the 42mm Polaris, and while the new watch doesn’t get rid of the problem completely (there’s still a sloped movement ring), it’s a noticeable and welcome improvement. As for the changes, the most noticeable difference is that the movement screws are no longer blued, which is a shame considering JLC’s claim to fame is their calibre-making prowess. Overall, however, the decoration is very pleasant (though industrially applied), and specs are strong. The Polaris is subject to JLC’s 1,000 Hours Control testing (including shocks, temperature changes, and other daily challenges, though no accuracy claims), beats at 4Hz and sports a 70-hour power reserve from a single barrel.
Magic on the wrist
Waxing lyrical about how all these changes are great is one thing, but how does this thing actually wear? Thankfully, that’s a simple answer – it’s awesome. The mid-case sits flush with the back of the wrist, and the 47mm lug-to-lug is spot-on for my 16.5cm/6.5in wrist. Of course, it’s not the slinky slim experience you’d get from other JLCs like the Reverso or Master Ultra-Thin, but for a sporty watch, it’s exactly what you’d want.
I spoke about the dial changes, but not the overall execution. The mix of opaline and grained finishes to the blue lacquer are as stunning as they were on the 42mm variant, and I really appreciate the gradient effect. Even though they haven’t bothered to frame it, the softly rounded corners of the date window remind me of those you’d find on enamel dials, and I might actually prefer it over an applied or printed frame. Now, that said, would I prefer it without a date altogether? Yes. Yes I would. But let’s take it step by step – we have the 40mm case and better typography, a no-date variant can be the next improvement.
With a matching leather-backed fabric strap, the Polaris 40 would feel right at home on the wrist of a linen-clad, boat shoe-wearing individual, potentially even on the deck of a boat. The folding pin buckle strikes the right balance between the luxury of a butterfly-like clasp and the convenience of a pin buckle, and doesn’t add any unnecessary bulk. The one way this experience would be improved is with a rubber strap, which is not out of the realm of possibility considering other Polaris model already have them. The fabric strap is nice enough and would probably get more comfortable with extended wear (I only had the watch for a few days), but the stiffness did put me off a bit. While it’s not my thing on a watch like this, I did speak to a few people who expressed their wish for a bracelet, too. Understandable requests, as I see this being a real strap monster.
Conclusion: excellent sports watch, not a dive watch
Toeing the line between an all-out diver and a casual daily that’s happy to get wet every once in a while, the Polaris Date 40 doesn’t need ISO-pleasing unidirectional bezels and screw-down crowns to serve its purpose. Think of the gap between something like a Rolex Submariner and an Omega Aqua Terra, both in terms of pricing and functionality, and the Polaris fits perfectly. With that context in mind, it makes the new Polaris look good. It’s by far the most affordable member in its line-up (a whopping A$3,400 less than its blue-dialled 42mm counterpart), and undercuts pretty much all its big brand competitors including Glashütte, IWC, Blancpain, and Rolex.
That’s a pretty good spot to be in, and really, does it matter that this watch doesn’t have a screw-down crown, which seems to be the sticking point for so many? Watch collecting doesn’t need to be so formulaic that every release has to be pigeonholed into a pre-determined category with accompanying entry requirements. Every once in a while, a stand-out comes along that does everything it should, but just because it doesn’t fit into the prescribed notions that us watch collectors have, we often unfairly dismiss them. Apply whatever descriptor you want to apply to the new Polaris Date 40, but the fact that it’s a damn cool watch doesn’t change.
