Cartier Introduces the Santos-Dumont XL Hand-Wound (with Live Photos)

Mechanical once again.

Conceived by Louis Cartier for Brazilian aviation pioneer Alberto Santos-Dumont – who needed a timepiece he could read while flying – the Santos-Dumont wristwatch has the double distinction of being the first wristwatch designed from the ground up for men, as well as being the first-ever pilot’s wristwatch. Now the 116-year old design has just received its latest update with the unveiling of the hand-wound Santos-Dumont XL.

[Update March 23, 2020: Read the review with more photos.]

Though the Brazilian pilot got his wristwatch in 1904, it took until 1911 for the design to be sold commercially. For most of the century since, the Santos-Dumont has been part of the Cartier line-up in one way or another, often in gold but occasionally in platinum (one outlier was a special edition in titanium with a skeleton movement). The most recent facelift happened in 2005, which saw the unveiling of a version without a bezel.

The new Santos-Dumont XL in all three versions

Last year, the latest generation of the Santos-Dumont was unveiled, marking a return to the iconic Santos bezel with screws. For the first time ever, the Santos-Dumont was available in steel as well as two-tone steel and gold, along with the traditional all-gold case. However, the new Santos-Dumont didn’t quite receive unanimous acclaim because it was quartz movement. But now Cartier has finally unveiled what was long expected, the mechanical Santos-Dumont XL.

Measuring 46.6 by 33.9 mm and just 7.5 mm in height, the Santos-Dumont XL is bigger than the quartz models but is likewise available in three metals – steel, 18k pink gold, and the bi-metal combo of steel with 18k pink gold bezel.

The finishing of the case is classic Santos with alternating brushed and polished surfaces. The top surface and flanks of the case are brushed, separated by a wide polished bevel that accentuates the shape of the case, while the bezel is mirror-polished.

One subtle difference between the new XL model and the quartz versions is the fit of the strap: the strap for the XL watch has metal insert at both ends, allowing the strap to integrate into the case without a gap or play.

But perhaps the most striking aspect of the watch is the silver, sunray-brushed dial – another first for the Santos-Dumont which has historically been offered with either a guilloche or opaline dial. The radial finish further accentuates the elongated, reed-thin Roman numerals, creating a rather distinctive aesthetic.

Powering the watch is the hand-wound cal. 430 MC, which is actually the Piaget 430P used in its extra-thin Altiplano. A movement that’s both thin and small, the 430 MC unsurprisingly has a shortish power reserve of 38 hours.

Both the Cartier and Piaget versions of the movement are identical save for the finishing; Cartier’s iteration has its bridges and balance cock decorated with its double “C” logo.

Business News: Swiss Watch Exports to Hong Kong Post Biggest Fall in 20 Years

A weak outlook.

Trade body Federation of the Swiss Watch Industry (FH) just released its monthly export figures for Swiss watches – a proxy for the broader luxury watch market since Swiss timepieces dominate – and the February numbers are bleak.

The month’s statistics illustrate two obvious trends that have shaped in the industry recently: the COVID-19 coronavirus is having a massive impact, and low-cost Swiss watches are being trounced by low-cost smartwatches.

An Asian crisis, for now

Compared with February last year, the value of exports globally declined by 9.2% – with export volume plunging 22.2% – but as the report notes darkly, the drop “does not yet fully reflect the actual situation in certain markets.”

Unsurprisingly, the steepest declines were in the biggest Asian markets – China and Hong Kong – which suffered the worst period of the COVID-19 coronavirus pandemic in the first two months of the year.

The biggest fall was in Hong Kong, where exports fell 42% – the largest monthly decline in 20 years. The city imported just CHF143m of Swiss watches, compared to CHF246m for the same month last year. Exports to China fell 51.5% to CHF73m, from CHF151m for February 2019.

February was merely an acceleration of a months-long decline. For the first three months of the year, exports to Hong Kong have fallen 33% compared to the same period last year, while exports to China are down 22%.

Though exports to other large markets like the United States, Singapore, and Germany increased, the trend will likely reverse as the spread of the coronavirus migrates west.

Cheap but no takers

The other salient detail in the decline was the weakness of low-priced watches. Two-thirds of the value of the global export decline was for steel watches, which accounted for 90% of the drop in volume.

Consequently, the sharpest declines in terms of price segments were seen in the cheapest watches. Exports of watches with export prices of CHF200-500 fell by 52.5%, while exports for watches below CHF200 as well as those between CHF500-3,000 declined 18% each.

In contrast, watches priced over CHF3,000 saw a negligible drop in exports of just 1.3%.

Hands-On: Romain Gauthier Logical One Byzantine

A one-off of the landmark watch.

The Romain Gauthier Logical One was launched in 2013 to critical acclaim, and clinched the year’s award for Best Men’s Complication at the Grand Prix d’Horlogerie de Genève (GPHG). While centred on the very old idea of a chain and fusée, the Logical One stood in contrast to contemporary wristwatches with the same complication.

Other watchmakers sought, single-mindedly, to miniaturise the chain and fusée – doubtlessly a feat of micro-engineering – but Romain Gauthier took a step forward and developed a truly modern incarnation of the constant-force mechanism that originated in the 15th century. And contrary to well-known makers of the chain and fusée today, most notably A. Lange & Söhne, Romain Gauthier ensured the chain and fusée in the Logical One is entirely visible on the dial.

Since its debut, the Logical One has been iterated multiple times, with variations covering the spectrum from traditional to ultra-contemporary. The attractiveness of the many versions vary – some are overdone – while others are a perfect fit for the impressive movement. One that works perfectly is the unique Logical One Byzantine that has the striking combination of a blue enamel dial and movement bridges bridges engraved with a motif inspired by Byzantine art. (Though this specific combination is unique, similar-looking examples have been produced, for instance with blue sub-dials but without engraving.)

Case and architecture

Due to the complex architecture of the movement – with includes the chain and fusee – the Logical One is big for a classical watch, measuring 43 mm in diameter and 14.2 mm high.

However, it does appear smaller because there are minimal protrusions from the case; the time-setting crown is flat and located at two o’clock. The mainspring barrel, on the other hand, is wound by a pusher at nine o’clock. Hence, though the case has a conventional round shape, these recessed details alter the way it wears and feels on the wrist.

The pusher that winds the mainspring

The bezel has a concave surface while the lugs are lengthy and curved downwards, offering a rather comfortable fit on the wrist.

Case finishing is beautifully executed; it is predominantly polished, but with recessed flanks that are frosted. The polished top surfaces of the case offer a great contrast against the frosted dial.

Visible on both the front and back, the movement is constructed with an unusual layout even for a fusée-and-chain watch. The mainspring barrel, for instance, is located directly below the balance wheel.

The fusée and chain occupy the left half of the dial while the gear for the fusée drives the going train on the right half of the dial. Thus, the sub-dials for the hour and minutes and the small seconds are located on the top right, with the escapement entirely visible beneath it, with the especially designed balance wheel in place by a palladium-treated cock.

From the back, the view is equally complex and elaborate, with four layers visible, giving the movement great depth.

In fact, because of the numerous mechanical parts and minimal engraved bridge, it looks more mechanical than on the front. The going train bridge, engraved with the Byzantine motif, provides most of the decorative detail on the back.

Located at five o’clock is a power reserve display, and right above is a wide steel cock holding the rack that winds the mainspring when the pusher is depressed.

Exotic transmission

Invented when movements were regulated by verge escapements – which means a long, long, long time ago, starting around the 13th century – the fusée and chain is a primitive form of constant force delivery. Because a verge escapement had no hairspring – it was essentially a pivoting rod mounted perpendicular against a saw-toothed escape wheel – it were extremely sensitive to fluctuations in power delivered by the mainspring. The fusée and chain was developed to ensure an even supply of power as the mainspring unwound.

A traditional fusée and chain consists of a chain with one end connected to the barrel and the other to the fusée, a cone that sits on the centre wheel arbor. It provides constant force by relying on the principle of leverage, which is all about multiplying force when it is exerted further away from the fulcrum.

When the watch is fully wound, the chain is almost entirely wrapped around the fusee, so it pulls at the smaller circumference of the top of the fusée, exerting less force; conversely, as the barrel winds down, the chain gradually wraps around the barrel, and pulls at the larger circumference of the base of fusée, exerting more energy.

Part of the tiny chain is visible through the kidney-shaped aperture

However, the antiquated mode of delivering constant force is not without its limitations. The entire set-up occupies a lot of space, which means there’s less room left for other functions. At the same time, the length of the chain means its individual links are small by necessity, making them rather fragile. Because of the angle of the chain as it transmits force between the fusee and barrel, significant tension is created in the chain, which meant broken links were not uncommon in the chain and fusee mechanisms of old.

The Logical One delivers a unique twist to the concept, with several innovative solutions to improve its performance. The fusée, visible at ten o’clock on the dial is not actually a cone but instead a flat snail cam; it translates the three dimensional wide-to-narrow circumference of a fusee into a flat, two-dimensional shape with the same properties.

The snail cam is connected to an intermediary drive wheel at eight o’clock, rather than the barrel as is convention. And because the snail cam and mainspring barrel are on the same plane, there is no offset angle and force on the chain is always transmitted in a straight line, resulting in less stress on its links.

Despite being vastly different in shape and size, the snail cam delivers the same constant torque as a fusée, but allows the chain to be shorter, meaning its links can be larger, therefore sturdier and stronger. In addition, the chain is fitted with a synthetic ruby within each link to reduce friction as it travels from snail cam to barrel, and vice versa.

The heart cam is connected to an intermediary drive wheel by a short chain

And instead of a traditional crown fixed to narrow stem that has to transmit energy from the vertical plane of the hand-winding motion to the horizontal plane of the mainspring, the pusher-winder transmits energy to the barrel across the same plane.

Each push of the button at nine o’clock winds the barrel – a straightforward and intuitive method of winding. But because the button is flat and its motion shallow, it takes quite a few pushes, 40 in fact, to get to full wind. The overly tedious winding process is the primary downside of the winding mechanism.

Seen from the back, the barrel is seemingly open, but it is actually transparent. The cover and base of the barrel are sapphire crystal plates, meant to reduce the friction of the mainspring against the barrel interior, thereby minimising energy loss.

And mounted on the barrel cover is a black-polished  nut that holds down the mainspring.

With all that is going on with the constant force mechanism, other interesting bits of the Logical One often get overlooked, including the proprietary escapement and balance. The free-sprung balance wheel is Romain Gauthier’s own design, and held in place by a large palladium-treated cock.

Instead of a conventional, T-shaped pallet lever, Romain Gauthier’s version features a triangular form to improve stability and longevity. In a typical Swiss lever escapement, the escape wheel exerts a force in the opposite direction of the locking and unlocking action of the lever, which may cause deformation of the lever over time. A triangular structure thus offers greater support, since a triangle is more rigid than a “T”.

Stunning finishing

Romain Gauthier is probably best known for its finishing. So it’s no surprise the Logical One, front and back, is ever impressive. The movement was no doubt laid out in an creative way to exhibit the brand’s exemplary standard of decoration.

The sub-dials in this version are in blue grand feu enamel, while the gilded main plate and bridges have a frosted finish and a geometric pattern that required a hundred hours to engrave by hand.

Beautiful in its detail, the engraving is in relief and sharply done, even under magnification. It is reminiscent of engraved dials occasionally offered by F.P. Journe, especially the Régence Circulaire pattern found on the final edition of the discontinued Tourbillon Souverain.

Standing in contrast to the decorative beauty of the engraving is the mechanical beauty of the movement.

On the front, the bridge for the snail cam and the drive wheel as well as the cock for the balance have fully rounded, black-polished arms. The most subtle yet striking detail on the dial side is the tiny cock that secures the escape wheel; it boasts a deep inward angle on its chamfered edge.

If one were unreasonably demanding, there is one tiny aspect of the decoration that could be even more elaborate: a sharp, angular border between the jewel bearings to the rounded arm on the chain and fusee bridge.

The balance cock with sharp outward angles and rounded, polished arms

With more of the mechanics visible, the back of the watch is even more complex and offers more visible decoration.

The magnificent contours of the bridges and cocks allow for an abundance of anglage as well as inward and outward angles. In addition, the depth of the movement is further enhanced by a mix of brushed, frosted and textured top surfaces.

The finishing has been done to an obsessive level: even the slightest inner corner of the bridges is sharply bevelled while the edges of the bridges are finished with wide, rounded anglage. The screws and jewels also sit in wide, mirror-polished countersinks.

And to match the striking contours of the movement, all the wheel wheels, including the escape wheel, have Romain Gauthier’s signature circular spokes that bring to mind flowers. Similarly, all screws are proprietary and feature a patented, S-shaped slot that require a custom screwdriver.


Concluding thoughts

Seven years on, the Logical One remains the most impressive and superlative fusée-and-chain watch on the market. The extreme level of finishing, along with the innovation construction of the constant-force mechanism and movement, makes the Logical One an extremely unique and compelling proposition.

It is also unusual coming from an independent watchmaker, all other watches equipped with the same mechanism are made by establishment brands like A. Lange & Söhne, Ferdinand Berthoud (which is a sub-brand of Chopard), and Breguet.

The Logical One Byzantine has a price tag of 180,000 Swiss francs, compared to the 140,000 francs or so for the standard version without an engraved movement or enamel dial.

While the standard Logical One is fairly priced relative to the competition, especially given the finishing and architecture, the Byzantine one-off costs a lot more, which reduces the value proposition. That being said, while substantial, the surcharge is not outrageous as such things go.
