When you think of Navy SEAL watches you probably think rugged. Now you can also think slim.

The new Navy SEAL 3550 Series is still a beefy 44mm but it now has a revised shape and integrated strap create a much slimmer profile on the wrist. The bezel now sits flush with the case, the crown is better protected, and the slimmer hands echo the look of the earliest Luminox models. The textured rubber strap also looks more integrated than before, helping the watch feel less bulky.

Luminox says the goal was to create a watch that fits a wider range of wrist sizes without giving up the durability that has defined the collection.

That toughness remains intact. The 3550 Series offers 200 metres of water resistance, the familiar turtle-shaped case, and 16 self-powered Luminox tubes. Unlike painted lume, the gas-filled tubes glow continuously for years without needing to be charged by sunlight or another light source, one of the features that has always separated Luminox from many competitors.

The dial also receives a subtle update. The numerals are printed in Liberator Sans Heavy, the official typeface of the U.S. Navy, a small detail that reinforces the collection’s military roots. Turn the watch over and you’ll find an engraved Navy SEAL emblem on the case back.

The Navy SEAL line traces its history back to 1992, when Luminox worked with members of the U.S. Navy SEALs to create the Original Navy SEAL 3001. That watch became one of the company’s defining products and helped establish the brand’s reputation for practical military-inspired tool watches. Luminox continues to support the Naval Special Warfare community through its partnership with the Navy SEAL Foundation.

The new 3550 Series is a solid change to a classic line. Many modern tool watches have grown larger and heavier over the years, but Luminox has gone in the opposite direction. By making the watch slimmer and better balanced while keeping the features that made it popular in the first place, the company has produced what could become the new standard for its flagship collection. Basically, you’re getting all the ruggedness and luminosity of the original pieces with a case and body that won’t snag or weigh you down. At $595 these things are solid, handsome, and worth a look if you’re looking for a rugged beater.

Bremont has unveiled the Supernova Hawking Limited Edition, the brand’s latest collaboration celebrating the life and work of Professor Stephen Hawking. Building upon the success of its first Hawking watch introduced in 2020, the new release brings the partnership into Bremont’s contemporary Supernova collection with a design that draws inspiration from both modern space engineering and Hawking’s groundbreaking work on black holes.

The Supernova collection, introduced earlier this year, represents a new direction for Bremont. With angular architecture, integrated styling, and advanced materials, it takes visual cues from spacecraft and orbital technology while remaining rooted in the brand’s reputation for robust, adventure-ready tool watches.

The Supernova Hawking carries that philosophy forward in a distinctly thematic execution. The 41mm case is crafted from ultra black DLC-treated 904L stainless steel, paired with a multi-faceted black ceramic bezel and Bremont’s signature layered case construction. The result is an imposing yet highly technical aesthetic that feels equally inspired by aerospace engineering and the mysteries of deep space.

The dial is where the collaboration’s inspiration becomes most apparent. A galvanic black grid pattern references spacecraft solar arrays, guiding the eye inward toward the center of the watch. Meteorite subdials at 3 and 9 o’clock reinforce its celestial inspiration, while Stephen Hawking’s name and his black hole temperature equation appear at 6 o’clock as a tribute to the physicist’s pioneering theory of Hawking radiation. White Super-LumiNova-filled triangular hour markers and rhomboidal black gold hands provide strong contrast against the monochromatic design while preserving the watch’s futuristic character.

Inside, the chronometer-rated BC77 automatic movement delivers a 62-hour power reserve. Flipping the watch over reveals an exhibition caseback featuring a swirling black hole motif surrounding the decorated rotor, offering a fitting visual connection to the scientific achievements that inspired the watch. The Supernova Hawking is available on either an integrated ultra black DLC-treated 904L stainless steel bracelet or a black rubber strap, both featuring Bremont’s quick-release system for easy interchangeability.

Rather than relying solely on commemorative engravings or subtle references, Bremont has woven Hawking’s scientific legacy throughout nearly every aspect of the design. From the meteorite subdials and layered architecture to the exhibition caseback and inclusion of Hawking’s famous equation, the Supernova Hawking feels like a thoughtfully executed concept rather than a standard limited-edition collaboration.

Tim Hawking, Professor Hawking’s son, said: “This magnificent timepiece is a fitting celebration of my father and his work. He spent a huge part of his scientific and literary career exploring the mysteries of black holes and their role in shaping our understanding of the universe. His groundbreaking ideas opened up entirely new ways of thinking about the cosmos and continue to inspire scientists and explorers around the world today.”

A guest post by Sam Kovel

Founder and Editor-in-Chief of The Sunday Reserve, Sam is a lifelong watch enthusiast with a passion for craftsmanship, heritage, and the stories behind well-made objects. When he’s not covering watches and enduring brands, you’ll likely find him exploring the outdoors with his wife and daughter, enjoying a Negroni by the water in Long Beach Island, or searching for the next great cup of espresso.

Luminox has a new Navy SEAL watch out, and this one focuses on the brand’s usual mix of military styling, blacked-out looks, and heavy duty materials.

The new Navy SEAL 3500 Semper Fortis is limited to 775 pieces worldwide, a nod to 1775, the year the U.S. Navy was established. The phrase “Semper Fortis” means “Ever Strong,” and Luminox has built the whole watch around that concept. On the dial, the words “SEMPER-FORTIS” sit between 8 and 11 o’clock and are coated in Super-LumiNova. Underneath, “EVER STRONG” appears in red.

Col & McArthur have been around for a little over a decade now. They specialize in themed collections of watches such as “Battlefront,” “Visionaries,” “Interstellar,” and “Legends.” They often include physical representations of each theme in their pieces. Their Lunar Watch 1969 from the Interstellar collection includes a lunar meteorite fragment. Their Halliday 2017 timepiece from the Legends collection includes an “authentic fragment” of French rocker Johnny Hallyday’s jacket.

You get the idea.

They’ve now focused on the United States’ 250^th anniversary with their “Patriot 1776” offering. The hook with this new piece is the incorporation of an “authenticated 18^th-century musket ball recovered from a Revolutionary War battlefield” into each watch.

The musket ball, recovered from Fort Ticonderoga, is used as the material for the subdial. Bordering the musket subdial is the inscription, “Proclaim Liberty Throughout All the Land Unto All the Inhabitants Thereof.” Taken from Leviticus 25:10, these words are etched on the Liberty Bell in the City of Brotherly Love. Solidifying the theme is the seconds hand itself: shaped as the Liberty Bell.

Other design elements include engraved abbreviations on the dial for twelve of the thirteen original colonies as hour markers. Directly above those abbreviations, engraved on the case bezel, is the founding year for each corresponding colony. And since 12 hour markers only allow for 12/13 colonies, Pennsylvania is addressed on the caseback. The semi-exhibition caseback is handsomely done, incorporating a partial view of the movement (visible through a star cutout), along with names of some of the Declaration’s signatories and a portion of the Declaration’s text. It sounds busy, but its handled well. Other design features include 50 stars representing 50 states circling the inner track of the dial.

The watch is offered with two different movements. $899 buys you a steel case with a Swiss Ronda quartz movement. $2,499 gets you a Sellita SW360-1 automatic movement in a titanium case. There are additional pricing options depending on whether you prefer a leather strap or metal bracelet. The titanium-cased automatic movement comes in a limited run of 500 pieces. Each steel-cased quartz version is described as individually numbered.

Both versions of the watch have sapphire crystal and measure in at 43mm with a 20mm lug width. As this reads as more of a dress watch, I wish they could have made it 39mm.

One key design difference between the two models is that the quartz edition is no-date, while the automatic has a date window at 3 o’clock. This presents a dilemma as I believe the symmetry on this piece works better without the date, but I’d also prefer the Sellita movement. For anyone interested in picking one up, you’ll have a list of pros and cons to consider.

Some watches return because they are popular. Others return because collectors never stopped talking about them.

The new Doxa SUB 200 T.GRAPH II falls squarely into the second category.

Originally introduced in 1969, the T.GRAPH occupied a unique place in the Doxa catalogue. It was one of the earliest dive watches to incorporate a chronograph, arriving at a time when most dive watches focused on simplicity and ruggedness. Nearly six decades later, Doxa has revived the model as a permanent member of the collection, complete with eight references and a new Caribbean Blue dial that feels right at home alongside the brand’s classic colorways.

URWERK has never been interested in making ordinary watches. The Geneva-based independent has spent nearly three decades building machines that look more at home on the bridge of a starship than in a traditional watch box. Now the company is giving one of its most recognizable creations a final sendoff with the UR-120 Blue Planet, a limited edition of 20 pieces that closes the book on the UR-120 series.

The Blue Planet is the third and final version of the UR-120, a watch that became famous not only for its wandering satellite display but for a clever complication that causes its hour indicators to split apart and form a Vulcan salute. It is a fitting farewell for a watch that has always worn its science fiction influences proudly.

The new model is dominated by a deep blue colorway that gives the watch a different personality from previous versions. The sandblasted titanium and steel case measures 47mm wide, 44mm long, and 15.8mm thick. While those dimensions sound imposing, URWERK’s articulated lug system helps the watch sit comfortably on the wrist. A hidden spring integrated into the lower lug further improves wearability.

One of the most interesting aspects of the case is its construction. The watch is built around a two-part design consisting of a base and an upper shell that fit together seamlessly. The result is a smooth, uninterrupted surface that hides the complexity beneath. Viewed from above, the Blue Planet resembles a small spaceship more than a conventional wristwatch.

Inside is the self-winding Calibre UR-20.01, a movement that does far more than simply tell time. Three hour satellites orbit around a central carousel, each taking its turn moving across the minute track. As a satellite reaches the left side of the display, its two rectangular arms separate into a V shape before disappearing beneath the dial and resetting for another cycle.

According to URWERK, the carousel alone contains 175 components. The opening and closing of the satellite arms is controlled by a lyre-shaped spring, while Maltese cross mechanisms coordinate the movement of the display. The result is one of the most distinctive time displays in modern watchmaking.

URWERK has highlighted these components by coating the lyre springs and Maltese crosses in 24-karat yellow-gold PVD. Against the blue architecture of the watch, the gold elements stand out dramatically, drawing attention to the parts of the movement where energy is stored and released. Rather than serving as decoration, the gold helps explain how the mechanism works.

The movement beats at 4 Hz and offers a 48-hour power reserve. It uses a mix of materials including titanium, anodized aluminum, ARCAP, brass, beryllium copper, and LIGA-produced components finished with atomic layer deposition treatments. As with most URWERK watches, the technical specifications read more like those of an aerospace project than a traditional luxury watch.

The UR-120 Blue Planet is fitted with a blue Cordura-textured calfskin strap and is water resistant to 30 meters. Production will be limited to just 20 pieces worldwide.

Priced at CHF 115,000 before taxes, the Blue Planet occupies a rare corner of horology where mechanical engineering, industrial design, and science fiction storytelling meet. More importantly, it marks the end of one of URWERK’s most imaginative platforms. For collectors who appreciate independent watchmaking at its most unconventional, this final transmission from the UR-120 may be the most memorable one yet.

You know a watch is going to be cool when the entire website is in Italian.
