Longines Introduces the Record Heritage Chronograph

Longines is best known amongst watch enthusiasts for the Heritage collection of vintage remakes. The brand’s other offerings don’t usually enjoy the same level of attention – though the recent Master 190th Anniversary is an exception – so Longines is now adding some vintage flavour into its other lines. The brand’s latest is a mashup of its COSC-certified Record line and the Heritage collection. Unsurprisingly retro with a black gilt dial, the Record Heritage is the first chronograph in the Record collection, up to now comprised entirely of time-and-date chronometers. Initial thoughts Longines’ vintage-inspired chronographs are mostly appealing but Record Heritage still stands out because the brand hasn’t done too many with a black gilt dial. Looking both sporty and elegant, such dials are a favourite amongst collectors when it comes to vintage chronographs, and the look works just as well on a modern-day remake. That also means the Record Heritage is the most eye-catching watch in the Record collection, which was quite mundane until now. And unlike some past remakes that were too chunky, the Record Heritage has modest dimensions that vintage watch enthusiasts will appreciate. The case has good proportions overall and is just 40 mm wide, thought it is slightly thick due to the movement inside. More importantly, the dial has no date window to detract from its vintage aesthetics. Admittedly, the Record Heritage, like all Longines remakes, is neither origin...

TAG Heuer Introduces the Formula 1 X Mario Kart SJX Watches

TAG Heuer Introduces the Formula 1 X Mario Kart

With a near-unparalleled history in auto racing, TAG Heuer’s latest is a light-hearted take on its storied past. Inspired by the famous plumber now driving a go-kart, the Formula 1 X Mario Kart pair are both limited-edition chronographs, each opposing ends of the price spectrum. The base model is the Formula 1 X Mario Kart Chronograph with an “Easter egg” date display, while the top-of-the-line model is a variant of TAG Heuer’s tourbillon-chronograph with the COSC-certified Calibre Heuer 02T movement. Initial thoughts Pop culture adds levity to mechanical watchmaking and usually enhances the appeal, which is why the approach is a familiar one. Gerald Genta did it, and more recently RJ-Romain Jerome. TAG Heuer did it for the first time last year with the Connected × Super Mario that sold out swiftly, proving the appeal of the Italian plumber. But the Connected was a smartwatch, while the pair of new releases are both mechanical, so they have appeal for watch enthusiasts. The Formula 1 Chronograph is basic but affordable, and livened up by subtle-but-clever Mario elements, like a date display with symbols from the game instead of numerals. The Formula 1 chronograph The tourbillon, on the other hand, is essentially an amusingly whimsical iteration of TAG Heuer’s standard tourbillon-chronograph, while not costing that much more, making it a more compelling proposition than the somewhat plain regular-production model. Mario around the track Inspired by the Nintendo...

Ball Engineering Hydrocarbon NEDU Chronograph Hands-on Review

What we love: Proper solid built watch overallClasp feel very secure on the wristGAS Tube Lume is sensational at night What we don’t love: Thickness, at 17.3mm some may find this hard to wear under the cuff Some may find the crown guard to be fiddlySome may find the Clasp can dig into the wrist Overall rating: 7.5/10 Value for money: 7.5/10 Wearability: 7/10 Design: 7/10 Build quality: 8.5/10 Once upon a time, if you wanted a mid-priced automatic chronograph, chances are it’ll be powered by the ETA 7750 (or one of its close siblings), and the only choice really was the brand and the style. The movement was so ubiquitous that it was literally everywhere and fitted to almost everything. The dial layout was distinctive, and the rotor wobble was familiar, instantly giving away the engine within. Don’t get me wrong. This wasn’t a bad thing. The movement is a low key high achiever, easily running within COSC specs day in and day out without so much as breaking a sweat. It is a tough, durable, workhorse movement, designed from the beginning as an integrated chronograph, making it very efficient and the “almost 2 days” of power reserve is a testament to that fact. You might scoff at the power reserve but keeping in mind that this movement has been around since the 70s, largely unchanged, and 2 days was the norm for many decades. Plus, if you wear it every day, then it’s really a moot point. The only thing that might generate heated debate is how much value you attac...

Frederique Constant Introduces the Highlife Perpetual Calendar

Long focused on affordable mechanical watches, Frederique Constant continued with its specialty after its acquisition by Japanese watchmaking giant Citizen. Now the Swiss brand has just revived its bestseller from two decades ago, the Highlife collection, which has been redesigned extensively. It’s a new watch in all but name – the revamped Highlife harks back to the integrated-strap of the original, but it is a design very much catered to today’s taste. The Highlife Perpetual Calendar Manufacture The new Highlife collection debuts with three models that share the same tonneau-shaped case and integrated bracelet with quick-release pins. The most interesting watch of the trio is the Highlife Perpetual Calendar Manufacture, which is affordable despite its in-house movement and styling that’s reminiscent of more expensive watches. The other two models in the line up are simple automatics: one is time-only with an “Open Heart” dial revealing the balance wheel, and the other is a COSC-certified three-hander with date. Highlife Automatic COSC The Highlife Heart Beat Initial thoughts The Highlife manages to translate the look of high-end luxury-sports watches into an affordable watch by keeping a few design elements and simplifying everything. It is unavoidably derivative in style, but competently designed. So the 41 mm case is a simple affair with simple lines and surfaces, but dressed up with a polished, domed bezel. However, it avoids looking too plain even with t...

Breitling Introduces the Superocean Heritage ’57 Capsule Collection SJX Watches

Breitling Introduces the Superocean Heritage ’57 Capsule Collection

Following the Navitimer 1 Airline Editions and the Aviator 8 Curtiss P-40 Warhawk, Breitling has now introduced its next limited-production capsule collection, the Superocean Heritage ’57. Modelled on the brand’s first dive watch, the SuperOcean ref. 1004, the new range also includes a lively rainbow limited edition with multi-coloured hour markers. As scuba diving and other aquatic sports became popular in the early 1950s, dive watches being a thing, with the Blancpain Fifty Fathoms, Rolex Submariner and Omega Seamaster 300 all making their debut that decade. Breitling’s entry into the dive watch stakes as the SuperOcean. While the watch is now less known than its contemporaries, the SuperOcean had a strikingly bold and unusual design despite being some six decades old. It was characterised by a wide bezel with a concave surface intended to protect the domed acrylic crystal, and a dial featuring dagger-shaped indices with additional oversized spheres at the quarters. The quirky, retro style has been reintroduced in full with the Superocean Heritage ’57. Superocean Heritage ’57 Capsule Collection The capsule collection consists of three iterations: in stainless steel with a blue or black dial, and a steel case with a rose-gold bezel paired with a black dial. All are powered by the COSC-certified Breitling Caliber 10, which is an ETA 2892-A2. Entirely polished, the case measures 42 mm wide and 9.99 mm high, making it 4 mm thinner than the standard Superocean He...

Swatch Introduces the Big Bold Jelly SJX Watches

Swatch Introduces the Big Bold Jelly

One of the iconic Swatch watches from its 1980s heyday was the Jelly Fish (ref. GZ010), which was unveiled in 1983, the same year Swatch itself was launched. A quartz movement entirely exposed in a clear plastic case – accented with brightly coloured hands – the Jelly Fish was a bestseller that encapsulated what Swatch was all about: no-frills but fun watchmaking. The Jelly Fish remained in production, in one form or another – there was even a COSC-certified chronometer limited edition (GK124) in 1990 – for over two decades. Now the spirit of the Jelly Fish returns as the Big Bold Jelly, essentially the same idea but in a larger watch case. The Big Bold Jelly features a quartz movement inside a Big Bold case, just like the recent limited editions created in collaboration with fashion label A Bathing Ape (BAPE). The case is a large 47mm in diameter, with the crown unusually positioned at two o’clock. But just as with the original Jelly Fish, the case is clear plastic, while the band is translucent silicone. And the hands are rendered in bright colours – red, yellow and blue – with a bit more colour provided by the gilded wheels within the movement. Key facts and price Big Bold Jelly Ref.

Breitling Introduces the Navitimer Automatic 41 Southeast Asia Edition

The entry-level model in Breitling’s Navitimer line, the Navitimer 41 is a three-hander with date – plus the Navitimer’s trademark circular slide rule bezel. Already available in a variety of guises, it’s now available in a small, 36-piece run for Breitling’s Southeast Asian boutiques, with a blue dial and red gold bezel. The Navitimer Automatic 41 Southeast Asia Boutique Edition has a 41mm steel case, but dressed up with the rotating bezel in 18k red gold. As with all current Navitimers, the bezel has a “beads of rice” rim, a detail taken from the first generation Navitimer of the 1950s that was later replaced by a more functional knurled edge. To match the bezel, the hands and hour markers are plated in red gold, while the dial is a deep metallic blue. Though not available on the Navitimer prior to this, the combination is a familiar, having been used by numerous brands in recent years, especially with blue dials being fashionable now. And the movement inside the Breitling 17, which is a rebadged ETA 2824, a robust, no-frills movement, here with a COSC chronometer certification.

TAG Heuer Introduces the Carrera Heuer 02T Cortina Edition

Launched in 2016, the TAG Heuer Carrera Heuer 02T remains the most affordable Swiss-made chronograph with touribllon, starting at just US$17,000. Despite the price, the Calibre Heuer 02T is an in-house movement that’s automatic, COSC-certified, and equipped with a lightweight flying tourbillon that has a carbon composite upper carriage and titanium base. The latest variant of the affordable “grand” complication is a limited edition made for Singapore retailer Cortina Watch. Dressed in orange and back, the Carrera Heuer 02T Cortina Edition is being offered only online, via the retailer’s website. As with the standard model, the case measures 45mm wide and 16.4mm high. It features the modular construction that characterises the Carrera line. The case middle is black-coated titanium paired with a black ceramic bezel, while the lugs, pushers and crown are steel. The dial is semi-skeletonised to reveal the grey, sandblasted base plate of the movement. Orange accents are applied to the dial and bezel, including the chronograph hands, and even the carbon composite upper cage of the tourbillon, creating a striking contrast with the black components. Mechanically the movement is identical to the standard Heuer 02T. Based on the CH-80 chronograph movement, it’s equipped with a column wheel and vertical clutch for the chronograph. And it has a 65-hour power reserve, with the balance running at a frequency of 4Hz. Key facts and price TAG Heuer Carrera Heuer 02T Cortina Edi...

Christopher Ward Introduces the Military Collection SJX Watches

Christopher Ward Introduces the Military Collection

Founded in 2004 and selling its watches solely online, Christopher Ward has done some interesting watches at affordable prices, most notably the hand-wound, mono-pusher chronograph of 2017. But its latest is more straightforward: a range of watches inspired by vintage British military-issue timepieces. Unusally, the new models are licensed by the British Ministry of Defence to bear “the insignia of the Royal Navy, British Army and Royal Air Force” for public sale. While not actual military-issue watches, the line draws on well-known watches once supplied to the arms of the British armed forces, with the army and air force models managing to best capture the look of the originals. Christopher Ward, admirably, cites the exact vintage inspiration for each of the new watches, so the new dive watch, for instance, is loosely based on the Omega Seamaster 300 supplied to the Royal Navy. All three new watches have a “glass box” sapphire crystal, and are powered by a COSC-certified Sellita SW200, a robust and cost-efficient automatic movement. Each model is named after the respective training academy for the service arm, starting with the C65 Dartmouth. It’s named after Britannia Royal Naval College, which sits beside the port of Dartmouth in southern England. The case is steel, 41mm, and rated to 150m. According to the brand, it is modelled on the Omega Seamaster 300 “Big Triangle”, a specific type of the dive watch that Omega supplied to the Royal Navy...

Breitling Introduces the Revamped Avenger Collection

Launched by Breitling almost two decades ago as an upsized, sportier version of the then bestselling Chronomat, the Avenger has just been revamped into a streamlined collection made up of facelifted watches. Still retaining the styling of earlier generations of Avengers, the line is now made up of chronographs in three sizes (48mm, 45mm and 43mm cases), automatics in 45mm or 43mm cases, and a GMT. All models are rated to 300m and have a stainless steel case as standard. But the 45mm and 48mm watches are available in Night Mission livery – the best looking iteration – which means a black-coated titanium case and dial featuring military-inspired “stencil” numerals. Super Avenger Chronograph 48 Night Mission All the chronographs have the same basic specs, and the same COSC-certified Valjoux 7750 movement. The flagship model is the Super Avenger Chronograph 48, an enormous 48mm watch that’s probably too big for most, making the 45mm and 43mm chronographs more viable. The best looking watches of the line is the Avenger Chronograph 45 Night Mission, which manages to have a more modern military style that’s distinct from most other military aviation-type watches. Breitling ambassador and retired astronaut Scott Kelly The Average Automatic 45 Seawolf is a 45mm dive watch, powered by the Breitling Calibre 17, which is an ETA 2824. The specs are shared by the Avenger Automatic 43 that’s 43mm. Avenger Automatic 45 Seawolf And the last model is the Avenger Automati...
