Up Close: Vacheron Constantin Les Cabinotiers Minute Repeater Ultra-Thin “Thunder God” and “Wind God”

An exquisite pair inspired by a Japanese national treasure.

One of the most striking – no pun intended – timepieces created by Vacheron Constantin in recent memory are Les Cabinotiers Minute Repeater Ultra-Thin “Thunder God” and “Wind God”. Created for an Japanese-themed art exhibition in 2022, the two form a matched pair of striking watches, each featuring an miniature enamel dial reproducing one half of Wind God and Thunder God, a pair of folding screens so important they are a National Treasure of Japan.

Initial thoughts

Each year Vacheron Constantin (VC) introduces a sizeable Les Cabinotiers collection, typically several dozen watches in all, made up of one-off timepieces that are either complicated, decorated with artisanal techniques, or both. Last year’s line-up included a handful of ornate tourbillon watches and a diamond-set dragon watch. The “Wind God” and “Thunder God” duo, however, rank amongst the most impressive of the Les Cabinotiers.

“Wind God” and “Thunder God” are variants of the regular production VC minute repeater, which is ordinarily a somewhat plain, large watch with a slim profile. The 41 mm case of the repeater, however, makes it ideal as a canvas, particularly for artwork that is large scale in real life, as the Wind God and Thunder God folding screens are.

At a distance, both watches appear to be exceedingly plain, but up close each reveals remarkable miniature enamelling on the dial and a finely chased case accented by gemstones on the minute repeater slide. The case engraving is perhaps unnecessary, but the baguette-cut stones are tasteful.

Even though each watch offers a great deal of decorative detail, as well as a high-quality complicated movement, the highlight is the enamel dial. The two dials reproduce the famous folding screens in exceptional detail, even reproducing the gold-leaf surface of the screens in enamel.

The two watches are unquestionably beautiful in themselves, but also unusual in the motifs they reproduce. Watches that reproduce famous artworks are familiar enough, particularly in high-end Geneva watchmaking. Noted enamellers like Suzanne Rohr and more recently Anita Porchet have made careers in reproducing famous paintings in miniature enamel.

VC itself has produced various Les Cabinotiers watches in the past that reproduce artwork found in the Louvre and the Met – the most incredible is arguably the Vermeer grande sonnerie pocket watch – but East Asian art is less common in high horology, although Asian themes like the Chinese zodiac dragon are frequently employed.

Gods of wind and thunder

風神 (Fūjin) and 雷神 (Raijin) – literally translated as “Wind God” and “Thunder God” – are often depicted as a pair, sometimes as statues standing guard at the entrance to temples in Japan. But perhaps the most famous depiction of the two deities are Wind God and Thunder God, the pair of folding screens created by Tawaraya Sōtatsu (1570-1640) in the early 17th century. Regarded as one of the most accomplished and influential painters of the Edo Period, Sōtatsu helped establish the Rinpa School of Japanese painting defined by its use of vibrant colours and patterns.

Now on display at the Kyoto National Museum, Sōtatsu’s Wind God and Thunder God is arguably the definitive depiction of the twin gods – search for “wind god thunder god” online and all the leading results point to his painting. The screens are a National Treasure, the Japanese government’s highest level of recognition for a cultural object, but were already important in past centuries, so much so that they were reproduced by notable artists in the decades following Sōtatsu’s death.

Subsequent versions of the screens were painted by Ogata Kōrin (1658-1716) at the start of the 18th century and later that century by Sakai Hōitsu (1761-1829). Kōrin’s and Hōitsu’s versions of Wind God and Thunder God are significant artworks in themselves, with both being Important Cultural Property, protecting them from being altered or exported from Japan.

The watches each depict one screen from Sōtatsu’s Wind God and Thunder God but on a vastly different scale. The original screens each measure about 1.5 m high and 1.7 m wide, while the enamel dials are around 37 mm in diameter, or about 2% of the area of the screens. Despite the drastic change in scale, the enamel dials manage to capture the magic of the artwork. The work is all the more impressive considering how different enamel and gold are as a medium compared to the screens, which are in ink and colour on gold-foil paper.

Unlike the original screen, the two watch dials are signed by the enameller with “LR”, although his or her identity is unknown as VC is keeping mum. “LR”, however, deserves recognition for the magnificent work.

Both dials begin as blank yellow gold discs that are engraved by hand with the finest of lines to form the chequerboard pattern that replicates the gold-foil panels of the screens and accurately conveys the texture and ageing of the screens. Once complete, the engraved dial base is covered in a clear fired enamel, also known as fondant, in a technique synonymous with Geneva-style enamelling, which both protects the base and gives it a glossy finish.

Next comes the miniature enamel painting of each deity, with the “gold foil” enamel as the base. Each god is painted by hand and comprised of several colours. Because each colour has to be fired individually at a particular temperature, the deities are painted in steps and require multiple firings – between is and seven according to VC – to complete.

The marvellous miniature enamelling captures the depictions of the screens in extraordinarily fine detail. Just as Sōtatsu did on the screens, the gods are rendered in bold, wide lines. Each has a seemingly fearsome visage at a distance, but wide-eyed and slightly whimsical up close.

As on the original artwork, the gods appear to be substantial figures yet light enough to be floating amidst dark clouds, replicating the depth and perspective found on the screens. And the deities are painted close to the margins, resulting in negative space and a sense of visual drama.

Wind God with his windbag

To match the deity on each dial, each watch case is engraved with a corresponding motif – a scroll pattern for “Wind God” and stormy spirals for “Thunder God”. Although the engraving is complementary to the aesthetic, I would have opted out of it given the choice. Both watches have such impressive enamel dials that further decoration feels unnecessary.

That said, I do appreciate the gemstones on the minute repeater slide, which are decorative but discreet. Each case is set with six baguette-cut stones, tsavorites for “Thunder God” and rubies for “Wind God”.

Perhaps because of the engraving, both watches are unique in being Traditionelle models. There is no equivalent regular production Traditonelle minute repeater. The standard minute repeater instead is a Patrimony, which has softer, more rounded surfaces on the case. In contrast, the Traditionelle case is made up of flat surfaces and straight lines that are likely easier to engrave.

Mechanically, the two watches are identical to the standard models, save for the removal of the subsidiary seconds at nine. The cal. 1731 is a large-diameter, ultra-thin calibre that stands just over 3.9 mm high, about a fifth thinner than most repeater movements.

The movement has a contemporary layout featuring widely spaced bridges that reveal many of the moving parts. The gilded wheels of the going train are visible leading off from the balance wheel, along with all of the key elements of the repeater, including the secondary mainspring and a centrifugal governor shaped like the Maltese cross.

The cals. 1731 inside both watches are finished identically to the movements found inside the regular-production repeaters, so they are well finished though not quite to an artisanal haute horlogerie level.

Considering the price and unique nature of each watch, the movements could certainly do with a more elaborate decoration, especially something that echoes the dial motifs. In fact, I would have preferred the movement engraved instead of the case. And at this price level, VC might just accommodate such a request from the eventual owner of the pair.

Concluding thoughts

The price of the minute repeating pair is “on request”, though it is likely somewhere in the region of US$1 million. It’s not sensible to describe any million-dollar watch, or even a pair of them, as being reasonably priced, but “Wind God” and “Thunder God” are executed finely enough to make them almost reasonable and certainly one of most compelling propositions amongst VC’s Les Cabinotiers offerings.

Bulova Dress Up the Lunar Pilot with a Meteorite Dial

Another take on a "Moon" watch.

Something of an alternative “Moon” watch, the Bulova Lunar Pilot was unveiled eight years ago as a remake of the watch worn by American astronaut David Scott. It retains all the distinctive features of the original but made affordable thanks to a quartz movement. But now it’s a become a bit more luxe with a meteorite dial inside a scaled-down case.

Initial thoughts

As a space-watch aficionado, I find the Lunar Pilot more interesting than its more famous counterparts because of the unique yet contemporary design, particularly the modern typography on the chronograph registers.

After its debut, the Lunar Pilot was made more wearable with a smaller case size of 43.5 mm in diameter. Not much has happened since then, either in terms of dial variety or other innovation, limiting its appeal beyond a niche audience. Therefore, the meteorite dial version is a welcome development, particularly since the material is still uncommon in this price segment.

The meteorite edition, however, is pricey for the Lunar Pilot. It costs at US$1,495, a US$600 increase over the model with the standard dial. This price hike is arguably warranted since such dials are typically, but not always, found on more expensive timepieces. Despite being a limited edition, it is a run of 5,000 pieces, which isn’t exactly “limited”; a smaller edition size would have made it more compelling.

This is the latest addition to the space-inspired chronograph model introduced in 2016 that’s a remake of the ref. 88510/01, the model worn by NASA astronaut David Scott during the Apollo 15 lunar mission in 1971. Notably, the watch worn by Mr Scott was his own and one of two Bulovas he took on the mission; the other was a stopwatch. Mr Scott then sold the actual chronograph worn on the mission watch at Boston-based RR Auction in 2015 for US$1.6 million.

The Lunar Pilot of 2016 had a black dial with the modern-day Bulova logo and a large, 45 mm case. Following this, Bulova launched a smaller 43.5 mm model with similar dimensions as the vintage original, that was also available in a range of dial colours. The latest version identical in design to the regular production 43.5 mm model, though the materials differ: the case is a combination of titanium and steel, while the standard models are entirely steel.

And of course the dial is a slice of the Muonionalusta, considered the oldest known meteorite on Earth but common enough that is often used on watches. Like all such dials, the meteorite first undergoes an acid etching process to accentuate the Widmanstätten pattern – the randomly-linear motif formed by the crystalline structure of the material – before being polished and varnished.

The meteorite Lunar Pilot retains the NP20 High Precision Quartz movement (HPQ) found in the standard model. Running at an ultra-high frequency of 262.144 kHz, the chronograph can record elapsed times of up to 1/20th of a second. Like most Bulova movements, it is made in Japan by Citizen, the parent company of Bulova.
