My introduction to Atelier Wen’s Inflection came through the Massena LAB collaboration, the Inflection Shuò, presented at Geneva Watch Days earlier this year, and what caught me first was the shape. Integrated sports watches have become a long, sometimes repetitive conversation, but Atelier Wen’s curved surfaces offered something different, with a dressier appearance than much of the category.
The enamel-dial Inflection preceded that collaboration, launching in November of last year. It pairs the same tantalum case design with grand feu enamel dials made in Beijing and houses a Girard-Perregaux automatic movement. Tantalum has attracted growing attention among independent watchmakers for its dark, bluish-gray color and considerable heft, though its difficulty in machining and finishing keeps it relatively uncommon. Here, it extends through the case and every link of the optional bracelet.
The enamel-dial series comes in three versions: green 幽 (Yōu), black 墨 (Mò), and blue 渊 (Yuān). Green is a 30-piece launch edition, while black and blue are permanent variants, with overall production capped at 100 watches annually. Prices start at $19,800 on a strap and rise to $29,800 on the tantalum bracelet, putting the Inflection well above the Perception that helped establish the brand’s following.

Atelier Wen was founded in 2018 by Frenchmen Robin Tallendier and Wilfried Buiron, who met at the University of Warwick and both studied in Beijing. Tallendier’s interest in watches led him into local factories and workshops, while Buiron brought entrepreneurial experience and fluent Mandarin. The Porcelain Odyssey blossomed from this work that same year, with porcelain dials, followed in 2022 by the Perception, which paired hand-cut guilloché with a thin case and integrated bracelet.
The brand began experimenting with tantalum shortly after, showing prototypes of the Perception during Watches and Wonders in 2024. That September, the 25-piece Perception Hóng collaboration with Grail Watch brought the full-tantalum case and bracelet into production.
The Inflection introduced a new case and bracelet, grand feu enamel dials in place of the Perception’s guilloché decoration, and a customized Girard-Perregaux caliber. From the curved metalwork to the dial-making and movement finishing, the Inflection is arguably the brand’s most ambitious watch yet.

The case measures 40mm across, 45mm lug to lug, and 10.2mm thick, including the crystal. Those dimensions keep the Inflection relatively compact, though the tantalum gives it real weight. On the wrist, it feels closer to gold than steel, with a noticeably cool sensation when first put on. Tantalum conducts heat more readily than stainless steel, drawing warmth away from the skin.
The curves are what make the design work. Convex surfaces meet concave recesses throughout the case and bracelet, softening the outline while giving the different finishes clear boundaries. Atelier Wen draws on yin and yang here, expressing the idea through opposing surfaces rather than a literal symbol on the watch.
That bluish tone is tantalum’s natural color, brought out differently by vertical brushing, sandblasted accents, and mirror-polished chamfers. Like titanium, it tends to adhere to cutting tools during machining, increasing tool wear and making precise cuts more demanding. Finishing the recessed curves adds another challenge. That difficulty helps explain why tantalum remains uncommon in watchmaking, especially in a design that carries the metal from case to bracelet.
Brushed outer links, polished middle links, and concave chamfers carry the case’s finishing through the bracelet. The clasp offers four positions of on-the-fly adjustment, while quick-release fittings allow a change to the integrated sailcloth-and-FKM-rubber strap. Choosing the strap allows the wearer to retain a tantalum folding clasp while taking some weight off the wrist — and $10,000 off the price. A screw-down crown, 100-meter water resistance, and domed sapphire crystals, front and back, round out the construction.
[toc-section heading=”Three Grand Feu Enamel Dials”]
The Inflection’s dial pairs Arabic numerals and a fine minute track with sculpted leaf hands, leaving much of the enamel surface open. Atelier Wen worked with watch and typeface designer Lee Yuen-Rapati on the numerals, which draw inspiration from Chinese bamboo-leaf calligraphy. Their tapered strokes give the otherwise straightforward layout an unusual appearance.
All three versions use grand feu enamel dials made by Kong Lingjun’s workshop in Beijing on 925 silver bases. The process requires repeated firings at approximately 750–850°C, with a failed firing potentially costing the entire dial.
The black Mò pairs obsidian enamel with gilt numerals and rose-gold-plated hands. It has the familiar appeal of a vintage gilt dial, though the lettering and handset keep it recognizably Atelier Wen. The blue Yuān (seen here) uses white numerals and rhodium-plated hands against midnight-blue enamel. It’s a quieter alternative to the bright sunburst blues common to integrated sports watches, with the white lettering providing a crisp contrast.
The green Yōu is the most distinct of the three, with its hand-hammered silver base visible beneath translucent enamel, which graduates from pale green at the center to deep viridian around the edge. The texture and color bring anOrdain’s enamel work to mind, though the Inflection’s curved case and bracelet give it a dressier appearance.
I generally like leaf hands, and the hour and minute hands here have just enough oddness to stand out. Their deeply concave, mirror-polished sides give them volume, while the slender seconds hand has a leaf-shaped counterweight. The sculpted handset suits the case’s curved surfaces, and across all three versions, the dial work feels equal to the metalwork surrounding it.
[toc-section heading=”Girard-Perregaux Caliber GP03300″]
Inside is a Girard-Perregaux GP03300 movement, reworked specifically for Atelier Wen. The automatic caliber runs at 28,800 vibrations per hour, or 4 Hz, with 27 jewels, a 48-hour power reserve, and hacking seconds. According to the brand, it is adjusted in five positions and for temperature.
A GP movement is an unusual find in a watch from a young brand, though the manufacture has supplied other watchmakers over the years, including Daniel Roth, Harry Winston, and MB&F. The Inflection gives that established base a very different appearance, with openworked bridges and a rotor inspired by wind motifs in historical Chinese paintings.
Alfred Chan, the Atelier Wen designer behind the Inflection, worked with fellow watch designer Sidoine Lescauville and Girard-Perregaux’s technical team on the bridges. Their sweeping shapes have dark ruthenium plating, polished bevels, and sharp exterior angles, with laser-etched wavy stripes radiating across the surfaces. Black-polished screws contrast with the bridges, while rose-gold-plated spokes connect the rotor’s center to its tungsten winding weight.
The rotor follows the same wind-inspired design and is one of my favorite details of the watch. Together with the bridges, it gives the movement an appearance unlike much else, with finishing that holds up to the attention. A 48-hour reserve is fairly ordinary at this price, but there’s considerably more to appreciate through the caseback.
[toc-section heading=”Final Thoughts and Pricing”]
At $19,800 on the strap and $29,800 on the tantalum bracelet, the Inflection sits well above many established integrated sports watches. Girard-Perregaux’s steel Laureato 42mm, for example, lists at $15,000. The GP is sportier and made from a different material, but the comparison puts Atelier Wen’s pricing in perspective.
Tantalum has attracted other independent watchmakers, including MING with its 37.04 Tantalum monopusher chronograph. The AHA bracelet, designed by MING and made by J.N. Shapiro, offers another example. The Inflection combines that demanding metalwork with enamel dials and an unusually curved design. Still, the $10,000 bracelet premium is substantial. The strap offers considerable savings, though the bracelet’s continuation of the case’s curves is a pretty large part of the appeal.
The shape of the watch remains the main attraction, followed closely by the enamel dials and wind-inspired movement. It’s expensive, particularly from a comparatively young brand, but the finishing and design extend well beyond the novelty of tantalum. I like its dressier take on the integrated sports watch, and it gives a crowded category something different for enthusiasts to talk about. More info on atelierwen.com.
