With two most certain exceptions, the first wristwatch to have marked the beginning of an era was the Cartier Tank Normale released to the general public in 1919, designed by Louis Cartier in 1917, successor to the timepiece he created in 1904 for his friend Alberto Santos-Dumont, the Brazilian aviator. Before the two Cartier’s, in 1810 Abraham-Louis Breguet manufactured the first wristwatch we are pretty much sure actually existed for Caroline Murat, Queen of Naples, and in 1868, Patek Philippe created the second wristwatch we are also pretty sure of for Countess Koscowicz of Hungary. What made the Cartier Tank Normale unique was its square case which has aged so graciously over the past 107 years that it seems to have not aged at all, and it could (and should) be seen as the most resilient case shape horology has ever produced. It is so perfect that countless brands made their own versions of elegant square timepieces, and added a tad of creativity by morphing a square into a rectangle and made loads of them. 

In 2026, rectangular watches are still almost always synonymous with dress timepieces (though it would be nice to see rectangular tool watches, as one could selfishly hope for) and from the moment Nordic Marine Instruments reached out about its new collection a couple of months back, the Havørn, and the moment this review is being published, a smidge under 10 microbrands I am familiar with announced their own first rectangular collection. In other words, Nordic Marine Instrument has competition in this segment of horology, and standing out from the crowd it must in order to make the Havørn into a home run. So, as we will see, not only by its aesthetics but also by its specifications, NMI created something unusual for the genre of rectangular elegant timepieces, and the brand claims it is not what you think it is, it ain’t what I thought it was originally either, as it is endowed with a certain almost-hidden utilitarian charm the self-proclaimed avid collector of military tool watches that I am could not resist. 

Specifications

Picture yourself in the 1920s, sailing the North Sea aboard a single-mast boat, mindfully observing the sun setting in the horizon in strokes of burnt orange and red sparkling the darkening blue sky, wearing a heavy cream-colored wool sweater, holding onto the jib halyard with your left hand and a glass of red wine with your right one, looking down at your left wrist (I’m right-handed thank you very much!) to quickly glance at the time being displayed on your Ember Red Havørn—a delightful scene, isn’t it? That is one of the many places Nordic Marine Instruments would like you to project yourself into should it not be of you pulling the fishing nets back into the boat as you’re cruising past Bergen in Norway or reeling in the biggest catch of your day on the shores of Lake Vättern in Sweden. For even though the Havørn does have a major something of elegant horology we are meant to wear on the red carpet or seating front row of an opera at La Scala, it was thought through, designed, and spec’ed out to be more than this. 

And to better understand where the Havørn is coming from, we ought to refresh our memories about the previous Nordic Marine Instruments releases we have studied on Mainspring. The two previous collections we looked at from the brand were nothing like the Havørn and each told a different story, as the Søværn Stålgrå was an all-purpose everyday sports watch endowed with a bit of a minimalist core, and the Lunør Atlantic Blue was a de facto modern take on the moonphase stuck inside the body of an activity watch. They each looked different from one another and from the Havørn, they each were created from singular sources of inspiration, as is the Havørn, and they each revisited the categories within which they inhabited. Simply said, they were anomalies and were interesting for that reason, in addition to being visually and technically accomplished timepieces. With the Havørn, Nordic Marine Instruments is pushing us further to question what we know of styles of watches so that we can see it as being an actual sports watch. 

And we ought to do so not only based on the aesthetics and technical specificities of the Havørn but also through our limitless power of imagination and inner search for authenticity. For example, you may feel that ascending snow-capped mountains with an elegant sports watch was sensical in the 1950s, and that it would be equally sound of mind and spirit to do so in 2026 with a rectangular sports-watch-disguised-as-a-dress-one, instead of a hardcore utilitarian timekeeping device. Because you do whatever the hell you want and what makes you happy, and surprisingly, I for one could picture myself going on adventures with the Havørn Ember Red which is an image that I never thought would ever come to my mind. So why do I feel that? First, because the case, albeit it looks classic and swanky, is endowed with a muscular profile and a strong wrist presence no other rectangular timepiece ever had on my 6.50”/16.5cm flesh-and-bone apparatus. The latter measures 29mm across and 38mm long, 7.9mm thick and has a 20mm lug width. 

The Havørn’s case might generate different feelings on your wrist but that is came through my mind when I first strapped it on, and the strap is a second element that helps in categorizing this model more precisely: it is made of an outer sailcloth material with a matte finish, a leather lining, multiple stretches of stitching that make it look and feel durable, quick-release spring-bars, and a fully brushed stainless steel buckle. Should the Havørn be intent to only be worn during the Oscars, Nordic Marine Instruments would have communicated so by putting a fine Italian leather strap on it. Going back to the case, it is equipped with a guarded and knurled 5.3mm push/pull crown and screwed-in case-back, giving the Havørn a meager 30 meters of water resistance which however still fits the aforementioned idyllic scenarios . On top NMI put a curved piece of sapphire equipped with multiple layers of clear inner anti-reflective coating, and below it good applications of BGW9 lume on the hands and applied hour markers. 

Lastly, the Havørn is powered by a Swiss made Ronda 1062 quartz movement which has a stated accuracy of -10/+20 seconds per month and six years of battery life. So technically you could be sailing off to the sunset for six consecutive years without having to set foot on land to swap batteries. Pretty neat should you be able to nourish yourself with fresh air and sunshine only. 

Design

Obviously, the Nordic Marine Instruments Havørn Ember Red does not showcase the same type of specifications a hardcore utilitarian tool watch destined to be worn solo-circling the North Pole would have, and that is not the reason for its existence. For it forces us to rethink what we actually need to live our lives, whether we never cross the limits of the metropolis we dwell and work in, or are constantly wondering about exploring the countryside, hiking mid-sized peaks on the weekend, or even indeed sailing the North Sea hopefully aboard the ship and not swimming next to it. I don’t know about you (I really don’t by the way—who are you?) but I don’t need more than what the Havørn comes with 99.99% of the time and it would fair well in the off-chance I’m doing something a bit tasty when I’m not sitting in my office typing too many words about wristworn machines. Thus, technically the Havørn won’t measure up to an Omega Speedmaster X‐33 Marstimer but is enough, and visually it is endowed with a little something special. 

When I invited you to picture yourself sailing the North Sea holding a rope and glass of alcohol while freezing your butt off, I was projecting onto you the beautiful view offered to me by the dial of the Havørn whilst writing this article, from which emanates a decisive semi-elegant, semi-utilitarian vibe. First, on the lowest point of the dial, we find a CNC-machined jagged wave pattern representing the idea of a sharp object moving forcefully through the ocean’s waves (and NMI goes a step further mentioning the white-tailed eagle’s “Havørn” beak, its talons, or the sculpted edge of a Nordic coastline,) surrounded by a slightly raised track on which the single-dashes of the chapter ring are printed in white. North of the pinion the brand only needed to print its name, a touch of elegance which perfectly blends in with the patterned dial. And then, we come across what gives the Havørn an edge: applied, faceted, and dual-finished hour markers shaped like teeth at the cardinal points and slanted batons everywhere else. 

The markers occupying the 12, 3, 6, and 9 positions are further decorated with black painted lines on their outer top portions to have an extra smidge of legibility and visual differentiation. And we find the same lines nestled at the bottom of the hour and minute hands, fashioned into batons which taper down towards their edges akin to Dauphine hands, each being composed of a fully-polished slope and another one fully brushed one so that they are easy to see at any angle and under any lighting conditions. (Again, while you are checking the time riding into the sunset on the North Sea or accepting a Caesar on the French Riviera.) And then there is the case which further helps in defining the Havørn’s unusual nature: a stainless steel chassis NMI describes as being rectilinear, which means contained within straight lines, for it is made of two prominent upper-brushed and side-polished chamfered flanks joined together by two fully-polished flat bridges. From above the case resembles a window, from the side a sculpted tool. 

The Heart of the Matter

Everything technical detail of the Nordic Marine Instruments’ Havørn Ember Red that was related in this review, and how they match the attempt of redefining the classic genre of rectangular dress watches, put side-by-side with my own personal reading and interpretation of the watch’s dial and case design, further accompanied by how the whole makes me feel and what kind of images they prompt in my mind’s eye, explain the surprising power this model has on me—a self-proclaimed hardcore military tool watch enthusiast. And while I’m conscious that you and I might not see eye-to-eye on this one, you were curious enough about the Havørn to make it this far into this review. So at the heart of the matter today is the fact that Nordic Marine Instruments continues its own tradition of revisiting over-explored styles of watches through its own design and cultural lenses, bringing novelty within different categories, inviting us nerds and collectors to not only question what we think we know about these styles but also what they can be for us and not others. 

In other words: you could wear a 30m depth-rated, quartz-powered, and rectilinear elegant sports watch Havørn for your daily urban life as well as your outdoorsy adrelanine-inducing one,  should you chose to because technically and visually it fits the bill, regardless of what the Watch Wisdom tells us, thus subtly redefining a genre of timekeeping devices. Moreover, the Havørn did plant the unimaginable idea in my mind: what if I could also sport a rectangular timepiece? 

Conclusion 

The Nordic Marine Instruments Havørn Ember Red was a surprise and a delight of a watch, and I thoroughly enjoyed spending some time with it with the goal of telling you a (hopefully) compelling story about it. This new collection is launching today on the brand’s website for immediate shipping (no pre-order) at the meager price of $349 USD and comes in two additional colors: Arctic Silver which evokes the cold clarity of Nordic light on open water and Sky Blue whose dial colors shifts between grey and blue depending on the hour, the way the sea does when the sky above it cannot decide. (Quoting directly from NMI’s press release should you ask. There is a poet in each and everyone of us, isn’t there?) 

Thanks for reading.
