@hublot continues its sapphire story with the new Big Bang Sapphire Sky Blue, a limited edition that gives the material a light, summer-toned twist.

Produced in 100 pieces, the watch is housed in a 44mm polished sapphire crystal case with a matching bezel, a matte sky-blue skeleton dial and a structured sky-blue rubber strap. The effect is bold but airy, with the transparent case bringing extra depth to the watch’s openworked construction.

Inside is the HUB1201 manufacture manual-winding Meca-10 calibre, a movement first introduced in 2016 and recognised for its highly architectural layout. Built from 223 components, it features a distinctive rack-and-pinion style power reserve display and delivers a 10-day power reserve via twin mainspring barrels. ...

@cartier takes over Melbourne this winter with Australia’s largest exhibition dedicated to the Maison.

Now on show at the National Gallery of Victoria, Cartier: Melbourne Winter Masterpieces 2026 brings together nearly 400 jewels, timepieces and objects, tracing the Maison’s evolution from its Paris origins to the international house shaped by Louis, Pierre and Jacques Cartier.

For those drawn to Cartier’s timekeeping history, the exhibition includes early mystery clocks such as the 1914 Model A and 1923 Portique, alongside a 2023 single-axle creation. Watches are also well represented, with highlights including an original London Crash, a 1915 Santos and a 1920 Tank.

The exhibition also carries a local thread, from Australian opals to pieces linked to Dame Nellie Melba, placing Cartier’s global story in dialogue with Australia’s own cultural history.

Cartier: Melbourne Winter Masterpieces 2026 runs at NGV International until 4 October 2026.

After two decades defined by speed and visibility, @hublot is, today, taking a more measured approach. The brand’s focus returns to watchmaking, product and structure, while @k.mbappe Kylian Mbappé’s first watch for the brand anchors the moment in a FIFA World Cup year.

CEO Julien Tornare, is unequivocal about what the brand has achieved, saying it is “probably one of the biggest successes in the watch industry of the past 20 to 25 years”. Tracey Llewellyn explores how the brand plans to build on that success for daces to come.

The answer, a renewed emphasis on watchmaking, movement development, finishing, quality control and after-sales service. The Unico calibre is being pushed to the centre of the conversation.

On the product side, the Big Bang Reloaded Kylian Mbappé White Ceramic is perfectly timed. Not just for the World Cup, but for the future of the Big Bang. Its 44mm case combines white ceramic with 18K King Gold, while the skeletonised dial keeps the HUB1280 Unico flyback chronograph visible. The golden “10” refers both to Mbappé’s shirt number and the anniversary of his first professional goal.

Limited to 200 pieces, the watch is still unmistakably Hublot. The difference is that there is now a clearer effort to make the watchmaking carry as much weight as the image.

@vacheronconstantin introduces two new 34.5mm Overseas Self-Winding models, bringing more compact proportions and bolder colour to the collection’s sport-chic design language.

The first arrives in 18K 5N pink gold with a golden lacquered dial, creating a warm monochromatic look across the case, bracelet, markers and hands. The second comes in stainless steel with a deep red lacquered dial, paired with 18K white gold applied markers and hands for a sharper contrast.

Both models retain the key codes of the Overseas, including the hexagonal Maltese Cross-inspired bezel, integrated bracelet design and interchangeable strap system. Each watch is delivered with three options: a metal bracelet, a rubber strap and an alligator leather strap, allowing the watch to move easily between different settings. Inside is Vacheron Constantin’s self-winding Calibre 1088/1, offering hours, minutes, seconds, date and an approximately 40-hour power reserve. ...

@zenithwatches expands the DEFY Extreme line with two new high-frequency chronographs, each taking the collection’s bold architecture in a different direction.

The DEFY Extreme Lapis Lazuli II places its vivid lapis lazuli counters within a 45mm case construction that combines forged carbon with titanium elements. Limited to 25 pieces, the watch builds on the earlier Lapis Lazuli edition with a darker, sharper contrast between engineered materials and the natural depth of the stone.

The DEFY Extreme Ultraviolet takes a different approach, revisiting the violet colour language first explored by Zenith in 2020 and translating it into the more angular form of the DEFY Extreme. Its 45mm microblasted titanium case is paired with violet-tinted sapphire elements and matching subdials, giving the watch a darker, more graphic presence.

Both models are powered by the El Primero 9004, with one escapement beating at 5Hz for timekeeping and a second running at 50Hz for the chronograph. This allows the central chronograph hand to complete one full rotation every second, making the 1/100th-of-a-second display fully visible on the dial. ...

@jaegerlecoultre introduces @dlwlrma IU as its newest Global Ambassador through The Hour Before, a short film centred on craft, precision and control.

As IU assembles a Reverso case, the conversation traces the watch’s evolution from a sports watch created in 1931 to one of the defining design icons of the Art Deco era.

Its clean lines, bold geometry and measured design become a point of reflection for IU, whose own career has been shaped by dedication and a clear sense of identity.

It is a fitting beginning to the partnership, drawing a quiet parallel between the Reverso’s enduring form and the thoughtful artistry behind IU’s work.

@seikowatchofficial usually works at scale. The Star Time is the opposite: a one-of-a-kind mechanical watch created for baseball superstar @shoheiohtani Shohei Ohtani after 10 years as a Seiko ambassador.

The idea began with a question from Ohtani about how much time remained in his career. Seiko answered by building a watch capable of displaying elapsed time on a far greater scale than usual.

Five rotating discs track 24 hours, 1,000 hours, 10,000 hours, 100,000 hours and, finally, one million hours. Put another way, the outermost disc would take roughly 114 years to complete a full rotation.

The new module is based on an existing Seiko movement and housed in a high-intensity titanium case. Diamond markers indicate the zero position of each disc, while an oversized “17” references Ohtani’s jersey number.

it’s a remarkable watch that is unlike everything else Seiko makes, while also being completely on brand. ...

Andrew Garfield was seen at Wimbledon wearing @iwcwatches’s new Ingenieur Automatic 35 with Pool dial, giving the latest addition to the collection an early moment in the spotlight.

The new Pool shade brings a bright aquatic tone to the Ingenieur’s signature Grid-pattern dial, giving the watch a lighter and more playful expression. Housed in a 35mm stainless steel case with an integrated bracelet, it pairs compact proportions with the familiar Genta-inspired design codes that continue to define the collection.

A mix of satin-brushed and polished surfaces adds visual contrast across the case, bezel and bracelet, while the sapphire caseback reveals the automatic Calibre 47110. The movement offers a 42-hour power reserve and is finished with circular graining, Geneva stripes and a gold-plated oscillating mass. ...

Last week brought a mix of yellow sports watches, city editions, meteorite dials and a field watch tied to one of this summer’s most anticipated films.

@greubel.forsey introduces the Balancier QM, the first watch to carry its Qualité Musée standard, formalising the level of hand finishing long associated with the Atelier. @czapekgeneve, meanwhile, brings a light denim-blue Gibeon meteorite dial to the Antarctique Frozen Meteor, offered in 40.5mm and 38.5mm limited editions.

@breitling honours cycling legend Eddy Merckx with a yellow-dial Top Time B01, while @bellrosswatches turns the BR-03 into a helipad-inspired display with yellow air-rescue cues.

@parmigianifleurier continues its Ultra-Cermet story with the Tonda PF Sport Chronograph Ultra-Cermet Mineral Blue, while @zenithwatches and @mbandf turn to city-specific editions: a France-exclusive Chronomaster Original Paris Edition and the 25-piece LM101 EVO NYC.

Sport also runs through the week, from @richardmille’s RM 64-01 Tourbillon Colnago, linked to high-performance cycling, to @tagheuer’s Formula 1 Chronograph x Gulf, dressed in one of motorsport’s most recognisable colour schemes.

@chronoswiss_official brings two different takes on gold with the Opus Dakar Sundown and Pulse GMT Frosted Guilloché Gold, while @longines returns to the Conquest Heritage Central Power Reserve with a light blue opaline dial and its distinctive power reserve display on rotating discs.

Closing the selection is @hamiltonwatch’s Khaki Field Auto The Odyssey, a bronze limited edition created with Christopher Nolan and tied to one of this summer’s most anticipated films.

As America marked the Fourth of July, it felt like the right moment to look back at one of the country’s great watchmaking names: @hamiltonwatch

Today, Hamilton is perhaps best known for its long relationship with cinema, having appeared in more than 500 movies and television shows. But long before its watches found their way onto the silver screen, Hamilton was already deeply woven into the American story.

Founded in Lancaster, Pennsylvania in 1892, the brand emerged from a city that had spent years trying to build a serious watchmaking industry. What Hamilton brought was focus, discipline and industrial momentum, eventually becoming one of the defining names of American precision.

Its story runs through the railroad era, when accurate timekeeping became a matter of public safety; through World War II, when Hamilton halted civilian production to support the war effort; and into the electric age, when the Ventura gave the brand one of the most recognisable watch designs of the 20th century.

Hamilton watches may no longer be made in Lancaster today, but the city remains central to the brand’s emotional power. From railroad pocket watches and marine chronometers to the Ventura and its Hollywood legacy, Hamilton’s American story still has a place, a memory and an address.
