#TBT A Trio Of Oddball Watches From A Former President Of Cartier - Ralph Destino

The idea of “going round in circles” is often used as a synonym for not achieving anything. This is because, when moving in circles, you keep returning to the same point where you started, having made an effort to advance without actually achieving anything. But when it comes to watches, this is not necessarily a […] Visit #TBT A Trio Of Oddball Watches From A Former President Of Cartier - Ralph Destino to read the full article.

Insight: The Advantages of a Vertical Clutch Chronograph

The vertical clutch has become the de facto standard in modern chronograph movements thanks to its mechanical and practical benefits. The widespread and varied use of the vertical clutch is illustrated by the many recent movements that employ the mechanism, ranging from the Rolex Cosmograph Daytona to the Breitling B01 to the MB&F; LM Sequential Evo. The proliferation of the vertical clutch is easily explained by its merits. Having explained the construction of a vertical clutch, we now turn to its advantages over the traditional horizontal clutch (or lateral coupling). Figure 1: A simplified cross section of a vertical clutch A vertical clutch serves to transfer energy from the going train of the movement to the chronograph going train, accomplishing this via a vertical motion. Figure 1 illustrates its key parts: a flywheel (yellow) geared to (or even part of) the going train; a cone (grey) that is linked to the chronograph seconds mobile, and vertically tensioned by a spring (red); a pair of pincers (blue) that engage with the cone, lifting or lowering the cone.  When the cone is raised and engaged with flywheel, the chronograph starts running, and when the cone drops and disengages, the chronograph stops. One of the most apparent advantage of the vertical clutch is the low kinetic friction generated during coupling and uncoupling of the chronograph, as friction is produced only by the sliding motion of the pincers and the vertical motion of the cone. The Rolex Cosmogra...

Kollokium is Back with “Variant d” of the Projekt 01

The still somewhat mysterious Kollokium project is back with its latest release, a new variant in their first series, dubbed Projekt 01. The Kollokium drops this year have reminded us, for better or worse, of the limited edition releases that dominated the pandemic era of watch collecting. In other words, watches timed to a worldwide release window, which starts a frenzy and inevitably ends up in many being disappointed when they miss out on snagging one. It seemed like these happened a few times a month in 2020 and 2021, but this cycle has slowed down significantly as the watch industry has normalized a bit over the last few years. I think it’s too Kollokium’s credit, then, that they’re still able to gin up a level of excitement for their watches that is capable of leaving people in a state where they inevitably lash out via keyboard. It’s also worth noting that these watches are still genuinely scarce enough that when they pop up on auction sites or the pre-owned market, they tend to command a hefty premium.  All of this, of course, is secondary to the merits of the Projekt 01 as a watch, and I still believe that Kollokium is doing something that is pretty genuinely interesting at a price point (at retail) that feels approachable. The brand, you’ll remember, was founded by watch industry veterans Manuel Emch, Barth Nussbaumer, and Amr Sindi, who collectively represent the business, design, and collecting sides of the community, with overlap across all three fo...

30th anniversary of the Audemars Piguet Royal Oak Offshore: ROO F1s, High Octane Fairy Tales of Super Star Racing Drivers

The Audemars Piguet Royal Oak Offshore limited editions dedicated to the world of Formula 1 are one of the most interesting chapters in the history of the Offshore collection, which turns 30 this year. The release of such Offshores did not last long, from 2004 to 2012. Many of us were there, but for many everything was somehow forgotten and it is worth refreshing memories.

Explained: The Vertical Clutch of a Chronograph

Having already explained the more traditional horizontal clutch (or lateral coupling), we now look forward to the more modern vertical clutch. This is found in some of the most famous chronographs in contemporary watchmaking, including the Rolex Daytona with the cal. 4131 (pictured above), Patek Philippe Nautilus with the CH 28-520, and Audemars Piguet Royal Oak Chronograph with the cal. 4401. Arguably the most advanced type of chronograph coupling mechanism, the vertical clutch as it is known today was debuted in 1969 by Seiko in the 6139 chronograph. But the concept can be found in late 19th century pocket watches, and even the inexpensive Pierce Chronographe of the 1930s. Today it is practically the default choice for new chronograph constructions. Equipped with the vertical clutch, the Patek Philippe CH 28-520 in the Nautilus Travel Time Chronograph ref. 5990/1A Like its horizontal counterpart, the vertical clutch serves as the mechanical link between the chronograph mechanism and the going train of a movement, allowing power to flow from the going train to the chronograph, which then allows the chronograph to run. While it fulfils the same function, a vertical clutch works differently from the horizontal equivalent, a distinction that comes with its own set of advantages and disadvantages. How it works A chronograph vertical clutch is similar to the clutch found in the manual transmission of some automobiles. The clutch of an automobile enables the intermittent connec...

Minase and Fratello Collaborate for the Third Time with the New M-3 “Shiro” Worn & Wound

Minase and Fratello Collaborate for the Third Time with the New M-3 “Shiro”

Minase, the independent Japanese watch brand, and our friends at watch media outlet Fratello have collaborated on a third edition of the brand’s cult favorite M-3. After versions in purple and green each of the last two years, this latest release strikes a more classic and refined tone. The new M-3 “Shiro” features a white lacquered dial and some subtle but well chosen accent colors, all with an eye toward traditional Japanese craft.  “Shiro” is Japanese for white, and in Japan is historically a sacred color symbolizing spiritual and physical purity. It’s a color that is frequently worn by Japanese Emperors, and comes up frequently in Shinto rituals and traditions. For this M-3, Minase has given the dial a weave-like texture that recalls the garments that might be worn in such rituals. The dial has been coated with Japanese lacquer, and the brand promises the result is a dynamic silvery color with plenty of depth.  Other callouts to Japanese culture include the red tipped second hand, a color that symbolizes good luck. The precise shade of red chosen for this edition, “Hinomaru,” translates roughly to “circle of the sun.” And the blue strap, according to Minase and Fratello, is a tribute to Japanese denim. Fratello and Minase see parallels in high craft denim to traditional watchmaking, noting that good denim, when taken care of, is meant to last a lifetime, just like a mechanical watch.  The original impetus for the Fratello x Minase collaborations ...
