The refreshing Brellum Pilot LE.3 Power Reserve Chronometer

The brief at Brellum is usually quite simple, I presume. Create well-specced watches, in limited numbers, while minimising mark-ups. That last part is an often-heard filler for independent brands, but it’s also where Brellum differs from many - offering proper substance. The new Brellum Pilot LE.3 Power Reserve Chronometer happens to be one of the more … ContinuedThe post The refreshing Brellum Pilot LE.3 Power Reserve Chronometer appeared first on Time+Tide Watches.

Tudor Introduces the Pelagos FXD “Marine Nationale” SJX Watches

Tudor Introduces the Pelagos FXD “Marine Nationale”

Earlier this year Tudor resurrected its partnership with France’s navy, the Marine Nationale, some two decades after it last supplied military-spec Submariners to the navy’s divers. Now the brand has finally revealed a project two years in the making, the Pelagos FXD “Marine Nationale”. Developed together with the members of the Commando Hubert, the navy’s elite combat divers, the Pelagos FXD is an actual military issue timepiece – the unit’s divers wear the same watch during operations – with fixed bars and a no-nonsense aesthetic. The Pelagos FXD is a time-only diver just like the Submariner ref. 9401/0 “MN” issued to divers of the French navy in the 1970s Initial thoughts Images of a Commando Hubert graduation ceremony appeared online several months ago, revealing the watch. So the Pelagos FXD was expected, but still manages to surprise. It is clearly a nod to the ref. 9401/0 “MN” of the 1970s – nicknamed “snowflake” after its hands and dial – and is as close to a vintage Submariner as a modern Tudor can be. But it still has a few extras appeal to military watch aficionados. The fabric strap has a Velcro fastener so it can be adjusted more precisely to any wrist size Most notable are the lugs, which are a reinterpretation of the fixed bars found on vintage military-issue dive watches. They form one piece with the case, making the connection between the case and strap far more robust. It’s certainly over-engineered for anyone who isn...

Hands-On: With The L.U.C 1937 Classic Pink Gold, An Elegant In-House Chronometer From Chopard (Live Pics & Pricing)

Chopard's L.U.C collection contains a number of very interesting watches that range from simple time-only pieces to perpetual calendars and tourbillons (and even a cool table clock). At the more accessible end of the scale, we have the L.U.C 1937 Classic, a three-hand watch with a discrete date window and an in-house, chronometer-certified movement. That this movement comes in an elegant, well-finished pink gold package makes it all the more appealing.

Bernhard Lederer Introduces the Central Impulse Chronometer

After Bernhard Lederer unveiled his impressive double-wheel escapement wristwatch last year, it was radio silence until now. As it turns out, Mr Lederer was working on refining the Central Impulse Chronometer, which is now being launched in its final, serial-production form. The new watch is essentially the same watch, but with a new and improved dial. The movement remains the same: equipped with a double-wheel escapement featuring twin going trains, each equipped with a remontoir d’egalité constant force mechanism – making it one of the serious chronometers in modern horology. Entirely revised is the dial, which now has more elegant design, with slim hour markers framing a chequerboard guilloche centre. And the dial now incorporates gains a symmetrical, figure-of-eight aperture that showcases the twin escapements and remontoirs, with each having its own seconds hand – both turning in the opposite direction. Initial thoughts The CIC is one of the relatively rare wristwatches to incorporate a double-wheel escapement. But what makes the CIC uncommon is its execution – its escapement is powered by twin individual going trains – a construction famously conceived by George Daniels for his pocket watches, most notably the Space Traveller’s Watch. Bernhard Lederer at his bench The degree of miniaturisation to fit such a construction into a watch puts the CIC amongst an exclusive class of timepieces that can be counted on one hand – made by George Daniels, Derek ...

Breguet Introduces New Looks for the Marine in Titanium or Gold

Perhaps the epitome of formal, classical style, Breguet took a more modern direction when it revamped the Marine in 2018, giving its line of sports watches a sportier and cleaner aesthetic. The overhauled Marine was launched in three models: the entry-level Marine 5517 (which we did a hands-on review of), the Marine Chronographe 5527, and the top-of-the-line Marine Alarme Musicale 5547. Three years on, Breguet is gently facelifting the Marine Collection with new variants in titanium or rose gold – blue dials for the titanium models and slate-grey for rose gold. Initial thoughts Although not the most novel – these are just new case and dial combinations – the facelifted Marine watches are nevertheless noteworthy simply because they look substantially better. For one, the blue dials on the titanium models are eminently more striking than the mid-grey of the 2018 models, which gave them a more industrial feel. At the same time, the sunburst finishing is more obvious in blue. And pairing of blue and titanium is also unusual, as Breguet usually reserves blue dials for its white gold watches. The Marine in titanium and blue Similarly, the new slate-grey dials for the rose gold models give them more character than the original versions in silver that lacked contrast. The juxtaposition between the warm case metal and the cool dial is intriguing and eye-catching. And the colour and brings out the wave guilloché better. Starting at US$17,300 for the ref. 5517 in titaniu...

Omega Introduces the Speedmaster Moonwatch Master Chronometer with Cal. 3861 SJX Watches

Omega Introduces the Speedmaster Moonwatch Master Chronometer with Cal. 3861

Long anticipated and widely discussed ahead of its release, the new-generation Omega Speedmaster Professional Moonwatch has finally arrived. Officially the Speedmaster Moonwatch Professional Co-Axial Master Chronometer Chronograph 42 mm, the upgraded version of the famous chronograph is an attractive blend of vintage design elements and modern movement technology. Launched in eight variants, the new Moonwatch line begins with the entry-level model in steel with a Hesalite crystal and solid back, with the top of the line model being the version in 18k Canopus gold, a white-gold alloy proprietary to Omega. The new Moonwatch in Sedna gold (left) and Canopus gold All the versions, however, share the same design features, as well as the cal. 3861, which is also found in the recently-launched Speedmaster Silver Snoopy Award. A new-and-improved version of the cal. 1861 that powered the Moonwatch for decades, the cal. 3861 boasts all of the technological bells and whistles that define Omega’s contemporary movements. The new calibre is also is partly responsible for a price rise, with the new Moonwatch being about 25% more expensive than its equivalent with the cal. 1861. The cal. 3861 under the display back; only the Hesalite-crystal model has a solid back Initial thoughts The new Moonwatch is appealing but predictable in packaging details taken from vintage Speedmasters along with the new cal. 3861.

Longines Introduces the Heritage Military Marine Nationale SJX Watches
Longines Introduces Aug 26, 2020

Longines Introduces the Heritage Military Marine Nationale

Longines’ momentum with retro timepieces continues with the new Heritage Military Marine Nationale. The new remake is clean and legible, just like its inspiration, which was made for the French Navy in 1947. The vintage original, the ref. 5774, was an instrument for shallow diving – albeit one without the familiar rotating bezel of a diver’s watch that wouldn’t be invented until the 1950s. Consequently, it was a clean and legible watch, and so does the vintage reissue. Initial thoughts The Marine Nationale recreates the feel of the original quite well, despite being substantially larger. That’s accomplished by retaining the proportions of the original, as well as smaller but important details, like the shape of the seconds hand and the vintage logo on the dial. And thankfully there is no date to ruin the symmetrical dial. Like most of Longines’ other remakes, the appeal of the Marine Nationale lies in its affordable price of US$2,000, which is strong value especially given the upgraded ETA movement within. The only weakness of the Marine Nationale – especially given it is a remake of a dive watch – is the minimal water resistance of just 30 m. Subtle reworking At 38.5 mm wide, the Marine Nationale is relatively small by modern standards, even though it has been significantly enlarged from its original’s 33 mm diameter. That said, the size of the remake is good, especially coupled with the relatively thick case, which preserves the proportions of the ori...

Breguet Introduces the Marine Haute Joaillerie 9509 Poseidonia SJX Watches

Breguet Introduces the Marine Haute Joaillerie 9509 Poseidonia

One of the grandest and oldest watchmakers in the world, Breguet was founded in 1775 and usually sticks to watches very much rooted in tradition. Even its high jewellery timepieces are elaborate and lavish, but still old school. The new Marine Haute Joaillerie 9509 Poseidonia, however, is a strikingly lively, ocean-inspired jewellery watch. Named after the Posidonia oceanica, a seagrass found the Mediterranean sometimes known as Neptune grass, the new Marine has an iridescent mother-of-pearl dial invisibly set with 85 gemstones to form an elegant floating-seagrass motif surrounded by baguette-cut gemstones. It’s very different from the usual Breguet fare – in a good way – especially in the coloured gemstone versions. The Poseidonia is available four variations, each distinguished by the combination of gemstones. While the diamond version is set only with diamonds, the emerald, ruby, and sapphire models are each set with a variety of gems – amethysts and tsavorites on the sapphire version for instance – to create a rainbow-hued decor. The ruby And emerald Initial thoughts Breguet has a penchant for making high-jewellery timepieces inspired by nature. Thematically, the Poseidonia is no different, but it is far, far more spectacular in visual effect. Going by the photos, the watch will no doubt be dazzling and unapologetically luxe – and a world away from the restrained elegance of the Marine for men. Watches that have been liberally set with gems tend to b...

Breguet Introduces the Marine Tourbillon Équation Marchante 5887 SJX Watches
Breguet Introduces Mar 21, 2020

Breguet Introduces the Marine Tourbillon Équation Marchante 5887

One of the most exotic Breguet watches in production today, the Marine Tourbillon Équation Marchante 5887 combines a tourbillon regulator, perpetual calendar, and running equation of time. Complexity aside, the watch is mechanically fascinating: the traditional complications within are executed in a modern and practical way. The equation of time, for instance, relies on an open-worked cam produced via the high-tech LIGA photolithography technique. And the tourbillon cage is lightweight titanium with a silicon escapement, while the automatic winding is equipped with a peripheral rotor. Breguet has now introduced a new version of the grand complication, in pink gold with a slate-grey dial. While it is mechanically identical to the two earlier versions – in platinum with a blue dial or pink gold with a silver dial – the new watch is striking and harmonious, shedding a bit of the sports-watch aesthetic of the Marine by way of the richer colours. Being a facelift, the dimensions of the watch remain unchanged. It is still a massive 43.9 mm in width, though a svelte 11.75 mm high, thanks to the ultra-thin movement inside. Like the movement, aesthetics across the case and dial are very much a blend of new and old. The case has the traditional fluted band, but is paired with modern integrated lugs. Similarly, the dial is solid gold and decorated with traditionally-executed guilloche engraved with a rose engine, but in a modern, stylised wave motif. In a nod to the age-o...

Omega Introduces the Constellation Co‑Axial Master Chronometer 39 mm

After having modernised the Constellation for ladies two years ago, Omega has just done the same for the men’s model, revamping the watch inside and out. Now the full range of Omega’s bestselling model line – the Constellation is likely the most popular watch model in China – has been facelifted. The new gents’ Constellation Co‑Axial Master Chronometer line-up is 26 models strong, all of which share the same basic specs. While the signature Constellation design has been retained, the case and bracelet has been sharpened with subtle improvements that given it a substantially different look. And the case is also larger, at 39 mm instead of the 38 mm of the earlier generation. But most importantly, the new model is equipped with a Master Chronometer movement containing all of Omega’s latest tech. Nip and tuck Available in steel, yellow gold, Sedna gold as well as two-tone combinations, the new Constellation retains the classic barrel shape with concave facets at the top and bottom lugs, as well as the four bezel “claws” at three and nine o’clock. The overall design is, in short, fundamentally the same, but it has been improved in finishing and style, inside and out. The lines and surfaces of the case and bracelet are now cleaner and more pronounced, at the same time accentuated with improved finishing. While the bezel claws keep their traditional polished finish, most of the other surfaces are now brushed, with the case and bracelet featuring polished be...

In-Depth: Quantifying Performance and Trade-Offs in Movement Design

There are a lot of traditions in the luxury watch industry. From the use of pegwood to polish bevels, to the Roman “IV” rendered as “IIII”, the culture of watchmaking is full of interesting customs passed down over generations. But the most fundamental tradition remains the reliance on incremental improvements towards better timekeeping. “Better” might mean absolute performance measured over a defined period such as an observatory trial (the objective of the superstar régleurs), or reliable long-term performance on the wrist. Regardless, for almost four hundred years the quest for better precision was the guiding principle of the trade. To paraphrase from historian David S. Landes’ Revolution in Time, “… it has always been the rule that the quality of [a watch] is a function of [its] precision.” Omega cal. 47.7 observatory chronometer, where the barrel and balance occupy almost all of the diameter. Image – Omega Today, some 50 years after mechanical timekeepers were left in the dust by their “better” electronic brethren, some makers of mechanical watches are more pious in their observance of this traditional approach to incremental improvement than their competitors.  And if we look carefully, we can quantify this difference in approach by looking at how different watchmakers choose to use the available energy within their movements. Our interest was to find a way to quantify which watchmakers are making high-performance timekeeping choices and ...
