Breguet Revamps Its Iconic Marine Collection

Breguet has long been a brand with a deep reverence to its history spanning over 250 years. In this tradition, Breguet’s designs have remained consistent and timeless. The brand’s Marine collection is a core part of this lineage, with roots that trace back to 1815 when Abraham-Louis Breguet was appointed watchmaker to the French Royal Navy by King Louis XVIII. At the time, these marine chronometers were crucial scientific instruments, but as years passed and needs changed, the collection later evolved throughout the 20th and 21st centuries. On the coattails of Breguet’s 250th anniversary last year, we’re really seeing the brand’s offerings come into the modern era with new design updates. The latest comes to the Marine collection, which the brand has revamped with a new aesthetic that aligns with its latest stylistic codes.Two references anchor the contemporary Marine line: the 5517, a classic time and date version, and the 5527, a chronograph. For the first time, both the Marine 5517 and 5527 will feature Breguet numerals and the “Quai de l’Horloge” guilloche pattern that was unveiled to mark the 250th anniversary. This motif takes its name from the address on the Ile de la Cite where Abraham-Louis Breguet established his workshop and where his early marine chronometers were produced. Its design draws inspiration from two sources: first, the contours of the Ile de la Cite and Ile Saint-Louis as well as the repetitive movement of ocean waves. Several other ...

Business News: Gallet’s Return Heralds Renewed Battle For Mid-Tier Priced Watch Segment Hodinkee

Business News: Gallet’s Return Heralds Renewed Battle For Mid-Tier Priced Watch Segment

Backed by Breitling's House of Brands group, Gallet's return was hotly anticipated and closely scrutinized. Priced between $2,900 for a three-hand Flying Officer model with date and about $6,700 for the vintage-inspired 'Classics' models, replete with Breitling B09 hand-wound calibers, the revived brand's pricing at Breitling boutiques is certainly aggressive.  Gallet's rebirth and price-category decision mark the most high-profile and ambitious attempt by the Swiss watch industry to reclaim a space it once owned but has largely ceded in recent years to so-called 'boutique' or micro-brands that have filled the gap left by traditional Swiss brands moving upscale.Over the past decade, brands have climbed the value-category ladder even higher, making fewer watches at higher prices. The so-called mid-tier premium—or luxury watches with an MSRP between $2,000 and $5,000—was once dominated by Swiss brands from Omega to Breitling to TAG Heuer and Jaeger-LeCoultre. And while TAG Heuer still produces plenty of watches in the category, including the solar-powered quartz Formula 1, much of its development and marketing resources have been focused on new pricier versions of classic chronographs housed in titanium or other lightweight materials including the highly innovative, but eye-wateringly expensive, Monaco 'Evergraph' retailing at more than $28,000. Several of the new Gallet watches are available on a steel bracelet that is the same used on some Breitling models. Photo Cre...

Rolex Daytona “Four Seasons” Set Shatters Auction Record SJX Watches

Rolex Daytona “Four Seasons” Set Shatters Auction Record

When we first reported on Rolex’s Daytona “Four Seasons” charity auction, we wondered whether the quartet could reach CHF31 million, the sum achieved by Patek Philippe’s steel Grandmaster Chime at Only Watch in 2019. We got our answer today in London, where the four Daytonas together raised £37.3 million, equivalent to CHF41.2 million, or approximately US$49.5 million. That comparison comes with an obvious qualification: Rolex’s total covers four watches, while the Grandmaster Chime result was for one. Nevertheless, it is an extraordinary sum for a quartet of chronographs sharing the same movement, distinguished by their unique combinations of precious metals and stones. The auction was hosted Phillips and conducted by Aurel Bacs. Summer led at £10.3 million, followed by Autumn at £10.2 million, Winter at £10 million, and Spring at £6.8 million. Most of the action occurred over the phone. Phillips describes the combined result as a record for a single consignment to a charity auction. All proceeds will benefit the Federer Foundation, which supports early education in Southern Africa and Switzerland, and Re:wild, the conservation organisation co-founded by Leonardo DiCaprio.

Visiting Manufacture La Joux-Perret SJX Watches

Visiting Manufacture La Joux-Perret

Manufacture La Joux-Perret (MLJP) has become an increasingly important supplier to the growing ranks of micro-brands and independent watchmakers, offering capable Swiss movements at accessible prices. Though a fraction of the size of its neighbour Sellita, the manufacture has expanded through a pragmatic combination of selective automation, a more focused movement catalogue, and careful investments in production. Its approach offers an instructive look at how Swiss watchmaking can remain competitive while retaining the skills needed to produce everything from solar quartz movements to hand-finished tourbillons under one roof. To find out more about MLJP, we visited the manufacture in La Chaux-de-Fonds, one of the historical centres of watchmaking in the Swiss Jura. A primer on MLJP The history of MLJP can be traced to the revival of complicated watchmaking in the early 1990s. Established by Jean-Pierre Jaquet in 1990 under his own name, the firm supplied specialised movements, including shaped calibres and complications, to the growing fine watchmaking segment. Among its best-known offerings of that era was a monopusher chronograph designed by François-Paul Journe and produced for clients like Franck Muller and Girard-Perregaux. Loosely related to the cal. 045MC that Techniques Horlogères Appliquées (THA) developed previously for Cartier, the platform remains in production today as the cal. A5000, one of the manufacture’s more upmarket movements. The cal. A5000 in an ...

Introducing: Ianos Amfivios (Live Pics)

What We Know Today, Ianos, the Greek microbrand best known for its Greek history and culture-inspired dive watches like the Avyssos and the Dytis, is back with a new dive watch that was never meant to be. When Ianos introduced the Dytis last year, it was noted as the last in a trilogy of dive watches from Ianos, after which they would move on to the next thing. Well, Ianos is still mostly sticking to that story, but in the meantime, we have the Ianos Amfivios, a civilian edition of a special-edition watch Ianos produced last summer for Greece's Underwater Demolition Command. The new watch, built on the same dive-watch platform as last summer's Dytis (which TanTan went hands-on with here), is a solid next step for a brand that has iterated gently, even as it's taken big aesthetic swings in developing its collection. And truly, few, if any, other watches on the market scratch the same itch as Ianos's watches do. That said, the Amfivios is about as mass-appeal a watch as Ianos has produced, thanks to the military-demanded touches that set it apart from the Dytis. The Amfivios is, for example, the first dive watch since the original Avyssos to include any kind of scale on the rotating bezel. And where previous Ianos watches have used the small seconds subdial as a visual gag, here it is a functional subdial, with hands, markers, and everything. That's not to say Ianos has purged all that makes these watches, frankly, a little funky, though. The unique date at 12 remains, with ...

First Look - Marco Tedeschi’s Impressive Central Floating Tourbillon in Black Aventurine

The Central Floating Tourbillon is not entirely new; the design has existed under the Kross Studio name since 2023, but the brand has since moved toward the more personal identity of Marco Tedeschi. This collection is a direct expression of the engineer-watchmaker’s mechanical philosophy; read him explain it in our interview here. The Central Floating […]

Gear Guide: Car Camping Essentials

Summer camping seems to get all the attention, but camping in the fall is the real MVP: changing leaves, cozy flannels, and way fewer mosquitoes buzzing in your ear. Two years ago I made the switch from sleeping in tents to spending the night in my Bronco Sport and I’ve learned a thing or two about best practices. Here’s my super condensed guide to enjoying the great outdoors from within your vehicle’s four doors. Mattress fitted to your vehicle Like almost everything in the gear world, quality can come with a steep price tag. The good news is there’s a wide array of options at different price points when it comes to a mattress to use in your car camping set-up. This option from deepsleep is spec’ed to my car and is frequently lauded by fellow owners in my Bronco forums. I didn’t want to drop $200 until I was sure car camping was for me, and went with a $70 option off Amazon. Amazon has a feature that will let you know if a piece of equipment is approved for your make and model, and it was accurate in my case – though I still measured the back of my car to check.  Car lantern Nature can be dark… like, really dark. Flashlights are fine when you’re on the move, but for camping in my car I definitely prefer a lantern. It casts a wider glow and stands on its own hands-free. Some people hang strings of lights from their trunks and I’m so here for the Pinterest aesthetic. It’s just not super practical for the way I do things. A no-frills Coleman lantern ce...

Breguet Expands Marine Fleet SJX Watches

Breguet Expands Marine Fleet

The Breguet Marine 5517 and 5527 chronograph have been with us since 2018, remaining largely unchanged even as the rest of the catalogue has been thoroughly modernised. Now, the Marine collection gets its refresh with new dials and a range of materials, from titanium to 18k rose and white gold. The Marine 5517 in titanium Initial thoughts The Marine is something of an outlier among high-end integrated bracelet sports watches, being one of the few designs that avoids the 1970s-inspired styling that dominates the segment. Instead, the Marine carries design DNA from the brand’s heritage producing marine chronometers, dressed in a suitably seaworthy case and bracelet (or rubber strap). One of the most notable design changes for the updated Marine is that the roman numerals have been retired in favour of Breguet numerals. This update gives the Marine obvious Breguet design DNA, but some may find the mix of traditional Breguet elements on the dial with the contemporary case too much of a clash. The Marine 5527 in 18k rose gold There’s little question about the overall quality of the Marine, but the pricing puts its head-to-head with popular models from Audemars Piguet, such as the Royal Oak Chronograph, which is actually $500 cheaper than the 5527 in 18k rose gold. That said, the titanium variants are priced competitively, relative to titanium sports watches of similar quality from the likes of Vacheron Constantin. Six references, with bracelet or strap A little against conv...

eBay Finds: a Wild LED Watch with a Great Name, an Unusual Favre-Leuba, Classic Seiko, and More

eBay Finds is back! This bi-weekly installment will feature a selection of watches currently listed on eBay that have caught the eye of editor Christoph McNeil (@vintagediver). If you come across any hidden gems on the ‘Bay drop us a note at info@wornandwound.com for potential inclusion. Vintage Omega Seamaster  Going to start this week off with a brilliant tropical dial vintage Omega Seamaster. The 14k yellow gold filled case measures 35mm, has classic slim lugs and is in solid, unpolished condition. The embossed Hippocampus caseback medallion is nice and bold. The black dial has a pleasing, even patina that gives it a mottled chocolate look. It has applied gold stick markers and gold stick hands. No date window. I’m not always a fan of patina, but I can definitely make the case for this example! The crown is signed with the Omega logo as it should. This is a front loading case and there are no pictures of the automatic movement but the watch runs per the seller.  View auction here Vintage Lord Elgin Millbrook  Next up is a sweet vintage Lord Elgin Millbrook tank watch from the 1950s. This beauty has a wonderful Art Deco look to it. The small (likely 25mm or so) case is in 14k yellow gold fill, and is in superb condition. It’s squarish with fancy angled lugs that look really sharp, no pun intended! The butler silver dial is excellent, with applied gold markers. The markers are Art Deco stylized Arabic numerals for 12, 2, 4, 8 and 10, with a small sub-seconds dial...

Bring a Loupe: An Omega Ranchero, A Cartier Santos Ghost, An Audemars Piguet Perpetual Calendar, And A ZRC Grands Fronds

Next week is October. October. Even for someone who literally has an ongoing documentation of each week through this column, that is mind-blowing. I hope whatever baseball team you're stoked about is doing well—my Twins fell off so long ago that I haven't even been paying attention—and I also hope autumn's making a decent entrance for you wherever you are. Scorekeeping last week's picks, the Omega Suverän sold for 9,600 DKK, the Universal Genève Cabriolet for 2,400 CHF, the Vacheron Constantin Overseas remains available, and the Zenith chrono for €3,000. Strays Photo courtesy of Huntington Company. Hermès watches hardly go unnoticed, but I love that some of their models still fly a good bit under the radar. The Cape Cod, for instance, is fantastic—interesting and elegant without being too weird. This one, the Grandes Heures, features an hour wheel that allows the hour hand to travel differently based on its dial position, meaning it covers more distance from 9-10 than from 10-11, and while that's not any foundation-shaking complication or horological advancement, it is, inarguably, very cool.  While the breadth of variations makes it hard to argue for any Datejust being superior, I'd argue the Rolex Boiler Gauge models deserve consideration in the top tier, and this one looks fantastic. I somehow went from never having seen the Omega Seamaster ref 196.0054 to spending an embarrassing amount of time looking into it, which is my very public plea for help and for ...

Interview: Fabrizio Buonamassa Stigliani and Vianney Halter SJX Watches
Bulgari unveiled Sep 25, 2026

Interview: Fabrizio Buonamassa Stigliani and Vianney Halter

At Geneva Watch Days, Bulgari unveiled its latest collaboration with an independent watchmaker, three years after a fateful meeting between Vianney Halter and Fabrizio Buonamassa Stigliani, Product Creation Executive Director at Bulgari. The Bulgari Octo Finissimo x Vianney Halter Both describe their encounter – seemingly improbable at first – as more natural than we might expect. It resulted in a watch they both describe as “half Octo, half Vianney”. Yet this was not simply a matter of grafting one aesthetic onto another; the collaboration went deeper. Two separate conversations bring the same themes into focus: human connection, constraint as a creative stimulus and, above all, the opportunity to learn from one another. Vianney Halter (left) with Fabrizio Buonamassa Stigliani. Image – Bulgari From Bulgari’s perspective, Mr Stigliani describes the Octo Finissimo as a model whose identity had become strong enough to withstand a much deeper transformation – and a manufacture challenged by the ideas of an independent watchmaker. Mr Halter, meanwhile, has long regarded collaboration as a means of moving beyond the boundaries and limitations of his own workshop – provided that the human relationship comes before the project. The interview was edited for length and clarity. Yannick Nardin (YN): Fabrizio, how did the idea of working with Vianney Halter come about? Fabrizio Buonamassa Stigliani (FBS): I’ve always been in love with the Antiqua. We went to see Vi...

Seiko freshens up its Seiko 5 field GMT with two new colours

When considering a highly functional, reliable, no-nonsense timepiece that doesn’t break the bank, Seiko 5 undoubtedly comes to mind. Seiko also changed the game for affordable complications when it released the Seiko 5 GMT in 2022, making mechanical dual-time watches accessible to a whole new audience. Seiko’s first foray into this territory took the form of the … Continued
