50 Years Of Automatic Chronographs And The Recent Debuts From Zenith, TAG Heuer, And Seiko Commemorating The Milestone Invention(s)

1969 marked the introduction of the world’s first self-winding chronographs. These were presented by Zenith with its El Primero, Seiko with the 5 Speedtimer, and an illustrious group consisting of Breitling, Heuer/Leonidas, and Hamilton/Büren, with the Chronomatic Caliber 11. Sabine Zwettler takes us through the history and looks at three of the latest-generation commemorative automatic chronographs by these early pioneers.

Biver Debuts a Most Sophisticated Micro-Rotor Calibre

Founded by the namesake father and son duo, Biver has just debuted its second model, the Biver Automatique. Though a simple a time-only watch with central seconds, in contrast to the preceding Carillon Tourbillon, the Automatique is equipped with an elaborately executed movement that’s arguably the most impressive recent automatic. Besides decorative touches like guilloche on the bridges, the JCB-003 also features details like a grande sonnerie-style winding click. The calibre is paired with a comparably elaborately constructed dial with solid gold appliqués that’s available in a variety of materials, including mineral stone like Pietersite. The JCB-003 Initial thoughts The Automatique is clearly meant to showcase the brand’s ability to create a highly finished and refined time-only watch that can compete with more established producers, both in terms of the movement as well as habillage (namely the dial and case). The highlight of the Automatique is the JCB-003 movement. Developed in partnership with movement specialist Dubois Depraz, the JCB-003 is quite possibly the most refined micro rotor movement on the market today. Though it is functionally simple, the movement boasts decorative and technical details along with a high level of finishing. The over-engineered caliber is meant to serve as a base for future complications, which makes sense considering the high cost involved in constructing such a movement. Amongst the calibre’s notable details is the grande so...

Longines Ultra-Chron: The World's First High-Frequency Dive Watch Retu Teddy Baldassarre

Longines Ultra-Chron: The World's First High-Frequency Dive Watch Retu

The Longines Ultra-Chron takes its most direct inspiration from a dive watch the brand introduced in 1968, but it also represents the culmination of Longines’ expertise in making high-frequency watch movements, which goes back more than 100 years. Longines’ century-plus quest for high-frequency timekeeping precision started in 1914, when it produced the first hand-held stopwatches (like the one below) with movements that measured time to 1/10 second thanks to their high-frequency movement, Caliber 19.73N, whose balance wheel oscillated at 36,600 vph. It continued with a modification of that caliber to achieve an astonishing rate of 360,000 vph, and a stopwatch accuracy of 1/100 second, in 1916; hit a new milestone with the launch of the Observatory Chronometer in 1959, the first wristwatch with a 36,600-vph movement; and culminated with the introduction of the Ultra-Chron Diver (below) in 1968, which became the world’s first high-frequency divers’ watch, housing the 36,600-vph Caliber 431. (Yes, this predates by one year the most famous high-frequency movement, the Zenith El Primero, though that movement also incorporated automatic winding and a chronograph.) The Ultra-Chron Diver provides the template for the all-new Ultra-Chron model, whose cushion-shaped stainless steel case spans a contemporary 43mm in diameter and 13.6mm thick as well as a 300-meter water resistance - an improvement on the vintage model’s 200-meter rating. Like its predecessor, and in th...

Introducing: The Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co Hodinkee

Introducing: The Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co

What We Know Today, Zenith introduces a new "Double Signed" program for its Calibre 135-powered G.F.J. collection, and its first entry in this series is a collaboration with a Japanese independent that might not require all that much introduction around these parts—Naoya Hida. The evolution of the G.F.J. line has not taken all that long, with its origins starting in 2022 with the Zenith Caliber 135 Observatoire Limited Edition, where ten Calibre 135 movements from the 50s were restored by Kari Voutilainen and introduced in watches done as a triple collaboration between Zenith, Voutilainen, and auction house Phillips. Just three years later, the Calibre 135 was revived as a modern caliber for a line called the G.F.J. (after Zenith's founder Georges Favre Jacot). In just a little over a year, we've seen three small runs of this watch introduced in different stone-dial and metal combinations—platinum with a lapis lazuli dial, tantalum with an onyx dial, and an upcoming yellow-gold GFJ with a bloodstone dial. In the meantime, this new Double Signed concept with Naoya Hida takes the G.F.J. in a very different visual direction. The hefty 39.15mm platinum case, with a thickness of 10.5mm and a compact lug-to-lug of 45.75mm, remains the same as other G.F.J. models. But that dial is unabashedly Naoya Hida, constructed out of solid silver with the distinctive hand engraving coming from the hand of master engraver Keisuke Kano, the man responsible for the hand engraving across al...

Highlights: Striking Complications from Patek Philippe and Audemars Piguet at Christie’s Hong Kong

Two leading practitioners of fine watchmaking, Patek Philippe and Audemars Piguet face off at Christie’s upcoming Hong Kong auction, Important Watches: Featuring “Kronos: Titans of Time”, “The Eternity” and “The Chronicle” Collections. The catalogue features blue chip high complications such as the Sky Moon Tourbillon, as well as under-appreciated neo-vintage discoveries, and the most striking of this selection doesn’t even chime. Lot 2424 – Patek Philippe Sky Moon Tourbillon Ref. 5002P-001 While Patek Philippe’s Sky Moon Tourbillon started as a supporting act to the Star Caliber 2000, miniaturising the latter’s planisphere with moon passage and phases, its mindshare has far surpassed its larger sibling. It was Patek Philippe’s most complicated wristwatch when first launched, and the super-watch of the 2000s. Collectors entering the watch world during that time speak of it with the same nostalgia and reverence 2000s kids give to the Bugatti Veyron. The design was rather contemporary for early 2000s Patek Philippe, and looks nothing like its successor, the baroque ref. 6002. At 42 mm in diameter, it was also notably large — the ref. 5016 with which shares most of its movement, was only 36 mm in diameter. It was forward thinking in another way, selling an extremely expensive, astronomical complication as an off-the-rack product, continuing Philippe Stern’s “build it and they will come” attitude that began with the Calibre 89. Patek Philippe’...

The Yacht-Master II’s Encore SJX Watches
Rolex unveiled Apr 15, 2026

The Yacht-Master II’s Encore

In a rather surprising move, Rolex unveiled a revamped and re-engineered version of the Yacht-Master II. Although the original was discontinued in 2024 the Geneva-based brand decided to give the quirky watch another chance at life, while also making the user’s life much easier.  Initial thoughts The original Yacht-Master II was undoubtedly a polarising timepiece. People would either love the bulky aesthetics or instantly dismiss it as an unpalatable timepiece. Add to that the complicated Command Ring bezel programming sequence for the regatta timer and the result is a perhaps the quirkiest Rolex creation in modern times.  Apparently the timepiece was performing well enough to warrant an encore. The Yacht-Master II was thus updated to include both Rolex’s latest innovations (such as the Chronergy escapement) and a revised user interface.  In terms of aesthetics, the 44 mm timepiece is still hard to love at first, but definitely not as excessive as past versions. The biggest change was perhaps the shift to a regular bi-directional 60 minute click bezel, which replaced the cumbersome Command Ring system used previously.  The ten-minute countdown markings were moved to a raised flange on the dial. The regatta minutes and seconds hands now turn counterclockwise, a suggestive way of approaching countdown.  Although few Yacht-Master II pieces will realistically be used for yacht race timing, the complication can be as useful as any given chronograph. The new caliber 4162...

Baltic Aquascaphe Review: The Microbrand's Cult-Classic Diver

A forerunner of both the rise of microbrands and the ongoing revival of France’s watchmaking industry here in the 21st Century, Baltic Watches emerged on the scene in 2017, originally as a Kickstarter project. Founder Étienne Malec discovered the inspiration for his watchmaking enterprise in his father’s watch collection and named the company in honor of his father’s Polish roots, after the sea off the country’s northern coast. The goal from the start, according to Malec, was to produce “timeless pieces, of the highest quality, for fair prices,” and most would agree that Baltic has delivered on this mission statement. Baltic watches are all assembled in a workshop in Besançon, France, the nation’s historical cradle of watchmaking, and evoke vintage timepieces like the ones Malec’s father collected and extensively catalogued in his journals. Here we will look at the Baltic Aquascaphe, one of their most recognizable watches. The first Baltic watches were the three-hand HMS 001 model, with a Japanese Miyota caliber, and the hand-wound Bicompax 001 chronograph, with the Chinese Seagull ST19 movement. While both these watches were successful, and put Baltic on its path to fan-favorite microbrand status, the small company has since become best known for its Aquascaphe series of dive watches. The Aquascaphe, which was launched in 2018, takes its design inspiration from early “skin diver” watches of the 1950s and ‘60s, with no small amount of influence from...

Finding My Seiko UFO 6138: A Collector’s Lesson In Humility, Patience, And Rediscovery

Vintage Seiko chronographs have a way of pulling you in. They’re mechanically ambitious, unapologetically ’70s, and just rough enough around the edges to feel honest. Spend enough time around references powered by the 6138 and 6139 calibers, and you’ll understand why so many collectors fall hard for them. My journey started in 2019 while stationed […] Visit Finding My Seiko UFO 6138: A Collector’s Lesson In Humility, Patience, And Rediscovery to read the full article.

Piaget Polo Review: How The '80s Luxury Watch Icon Holds Up

While it’s more widely known for its jewelry these days, Piaget, founded in the small Swiss village of La Cote-aux-Fées by Georges Piaget in 1874, has been a watchmaker from the beginning. Its original trade, in fact, was making movements, and the company began making complete watches in In the 20th century. Before getting into the Piaget Polo, it's worth it to get into the brand's history in thin watchmaking. Since 1957, when Piaget created the historic 2mm-thick Caliber 9P, the company has been world renowned for the elegant thinness of its watches and movements. The world’s thinnest self-winding mechanical movement, Caliber 12P, followed Caliber 9P just three years later, in 1960, and Piaget has building upon these foundations ever since. Its most recent triumph in this area was the Altiplano Ultimate Concept, which debuted in 2018 as a prototype and hit the market in 2020; the entire watch, case and movement, is just 2mm thick, matching the wafer thinness of the original Caliber 9P. Along with Bulgari, another watchmaker known more for its jewelry, Piaget continues to embody the ne plus ultra of what ultra-thin watchmaking can accomplish.  [toc-section heading="The Integrated Bracelet Era Begins"] However, while “thin and elegant” remains the calling card of the Piaget watch brand overall, the market was looking for something a little different - a little bolder, perhaps - in the 1970s. Audemars Piguet had introduced its groundbreaking Royal Oak “Jumbo...
