GONE IN 60 SECONDS: The most complicated wristwatch ever made – the Franck Muller Aeternitas Mega video review

[su_vimeo url=”https://vimeo.com/154855593″] Franck Muller has the rather grandiloquent sobriquet of ‘The Master of Complications’ – and this watch is the reason why. Superseding Patek Philippe’s Calibre 89 for the most complicated title when it was released in 2010, the Aeternitas Mega features a staggering 36 complications, 21 hands and a movement with no fewer than 1483 parts. More impressive … ContinuedThe post GONE IN 60 SECONDS: The most complicated wristwatch ever made – the Franck Muller Aeternitas Mega video review appeared first on Time+Tide Watches.

Hands On: Patek Philippe Calatrava 24-Hour Alarm 5322G SJX Watches
Patek Philippe Calatrava 24-Hour Alarm 5322G Apr 22, 2026

Hands On: Patek Philippe Calatrava 24-Hour Alarm 5322G

Patek Philippe’s mastery of complications is evident at all levels. The brand’s ability to elevate even simple complications is on full display in the Calatrava 24-Hour Alarm 5322G, a smaller and more focused take on the alarm watch than the discontinued spider-like Alarm Travel Time 5520P from 2019. This puts the most refined alarm movement on the market in the popular hobnail-flanked Calatrava case, capped with punchy green and blue fumé dials. Initial thoughts Launched in 2019, Patek Philippe’s Alarm Travel Time ref. 5520 was a polarising design from the start, with the appearance of four crowns - three of which were actually screw-locked pushers - when combined with the four lugs giving the watch an octopoid appearance. Looks aside, it was Patek Philippe’s first wristwatch with an alarm, and introduced a refined new calibre. This year Patek Philippe builds on that foundation without the travel time functionality and streamlined looks, eliminating the appearance of an awkward double crown setting system. There is no actual change to the base movement’s functionality - save the deletion of the travel time module. Perhaps a decade ago this bright green dial, or even the blue, would feel out of place in a high-grade watch, but today it fits right into the brand’s extremely colourful and contemporary catalogue. Even so, the dial design is sure to be polarising, especially the conflict between the 12 o’clock marker and alarm indicator, which the latter s...

Rolex Enamels the Daytona SJX Watches

Rolex Enamels the Daytona

This year’s Watches & Wonders got off with a strong start. Rolex unveiled a number of new models, with a strong accent on novel materials and precious metals. A first for the sporty landmark chronograph, the new Cosmograph Daytona comes with an enamelled dial. Initial thoughts Rolex is known in modern times for their mastery of both industrialised mechanical watchmaking and sound material science. The new Daytona is a product of the latter - it benefits from a new sort of ceramic bezel and notably a white enamel dial done a bit differently. At first sight, the new model reminds of the “Porcelain” Zenith-powered Daytonas. A sought-after configuration of pre-2000 Daytonas, the “Porcelain” was nicknamed as such due to the glossy finished white dial, which carried some resemblance to classic porcelain. Among Rolex’s most beloved models, the Daytona has seen a fair share of makeovers over the years. Most special editions took advantage of the motorsport heritage of the chronograph and others added gems and precious alloys to the mix.  The main selling point of this latest Daytona configuration is the enamel dial - a classic element which doesn’t normally connect to Rolex or to sports watches in general. What Rolex successfully did was raise the appeal of the Daytona beyond just a sports chronograph, without resorting to any loud gem setting or full precious metal construction. Instead, the brand opted for a quiet (but modern) enamel and a new bezel configurat...

In Depth: Breguet No. 160 Montre d’Or

Abraham-Louis Breguet’s No. 160 exists first as legend. The standard account describes a secret commission for Marie Antoinette, incomplete when she faced execution, requiring forty-four years to finish. Theft, recovery, mystery, and royal romance: the narrative contains all the necessary elements of mythology. Yet this fame is recent. From its 1783 inscription in the order books through the 19th century, the watch remained largely unknown outside the Breguet workshop but for a few private collectors. Only when Sir David Lionel Salomons acquired it, nearly 140 years later, did the wider horological world learn of its existence, thanks to his careful cataloging and the watch’s public exhibition in 1923. Salomons gave credit to Breguet’s mastery on a scale previously unrecognised, establishing No. 160 as the supreme example of complicated watchmaking and the prime masterpiece of its maker. Sir David Lionel Salomons’s 1921 work on Breguet and the collection he assembled seems to be the first source to mention Marie Antoinette. Image SJX composite – Sotheby’s Subsequently, many sources have reported that the commission demanded every known watch complication and that no time constraints or limits were placed on its design or cost. The workshop records, however, tell a story that differs from both obscurity and legend. No. 160 appears in the 1783 order books as three words: “No. 160, Montre d’Or.” The entry stands alone, anonymous, unexplained and without cont...

Grand Seiko White Birch Review: A Brand-Defining Future Classic Teddy Baldassarre

Grand Seiko White Birch Review: A Brand-Defining Future Classic

Grand Seiko is a brand that’s adept at making the intricate seem effortless. This talent for restraint is best demonstrated dial side, specifically with its play with textures that call for a second (or third, fourth, and so on) look. While the deceptively simple “Snowflake” dial is among the brand’s most renowned examples of its mastery of subtlety, today, I’m pulling focus to another iconic example of Grand Seiko’s dial mastery with the more dramatic White Birch variation. Down below, I’ll be breaking down the importance of the “White Birch” SLGH005 in Grand Seiko’s recent history, some of its guiding design philosophies, as well as all the necessary specs you need to know. [toc-section heading="History And Context"] Debuting in 2021, the SLGH005 with its “White Birch” dial marked a historic turning point for the brand, and in the years since, it has become regarded as an example of the brand’s strengths firing on all cylinders. Before its introduction, Grand Seiko had already become synonymous with intricately textural dials (which, of course, drew inspiration from the natural world), but the White Birch texture is really when the brand turned up the heat an extra notch.  Before, the brand largely relied on radial and horizontal textures, and it isn’t a coincidence that the continuous series honoring the Japanese micro-seasons (most famous being the “Shun-bun”) was already in play before the White Birch hit the scene. Many of these dials...

A Closer Look At COSC’s New Excellence Chronometer Certification

Contrôle Officiel Suisse des Chronomètres (COSC) is the largest Swiss independent testing facility for watch movements. Founded in 1973, this non-profit foundation aims to guarantee the precision of Swiss watches through a neutral, independent, and rigorous method. Watches with movements that passed the tests can be called “COSC-certified chronometers,” accurate to within -4/+6 seconds per […] Visit A Closer Look At COSC’s New Excellence Chronometer Certification to read the full article.

COSC Upgrades Standards to Certify More Than Timekeeping

Interesting news just out of Contrôle Officiel Suisse des Chronomètres (COSC), the venerable Swiss chronometer testing body, which has just announced a major revamp to its testing to honour the COSC’s standard’s 50th anniversary. Excellence Chronometer, COSC’s new and improved certification program, goes beyond the ISO 3159 norm that has defined its tests for decades. Instead of just testing movements, Excellence Chronometer will require completed, cased watches to run within -2/+4 seconds a day, as well as pass wear simulation and magnetism tests. Initial thoughts While COSC remains the primary chronometer testing body in Switzerland, thanks largely to Rolex, its protocols have been due for an update for some time now. With the rise of alternative and in-house precision testing programs, the standard chronometer certification can sometimes feel left behind. Rolex’s own Superlative Chronometer certification first requires a COSC certificate, but then makes sure the watches run at -2/+2 seconds per day after further in-house testing. The METAS Chronometer program also requires the standard COSC certificate, but guarantees a regulation of 0/+5 seconds per day and a great resistance to magnetic fields. Seeing that COSC slowly updates and imposes more stringent criteria is a good sign, but it may still not be good enough. With the rise of advanced internal certification programs, it looks like some brands submit their models to COSC testing just to make sure they can...

The COSC Introduces the New Excellence Chronometer Certification

The Contrôle Officiel Suisse des Chronomètres (COSC, the body responsible for certifying watch movements as Swiss chronometers) has just announced a new chronometry standard that will be rolled out over the course of 2026. The news comes at a time when the COSC has some competition for timekeeping certifications, most notably the METAS certification (which first requires a watch movement to be COSC certified) used by Omega and Tudor, as well as other certifications provided by the brands themselves.  The new COSC certification is being framed as an additional level of certification that will accompany the familiar “Certified Chronometer” tag that is seen on the dials and paperwork of millions (literally) of watches that have been put through the COSC paces over the years. The new “Excellence Chronomenter” certification provides an additional layer of guarantee of reliability that goes beyond simple accuracy. As a refresher, COSC certification certifies the movement is working at an optimal level, not a fully cased watch. To achieve a Certified Chronometer certification, a movement must show average accuracy of -4 to +6 seconds per day over a 15 day period, tested across 5 positions and 3 temperatures.  The Excellence Chronometer certification tightens the accuracy threshold from a spread of 10 seconds in total to 6 (-2 to +4 seconds per day). It also adds metrics for magnetic resistance and power reserve verification in fully cased watches. According to the COS...
