Louis Erard 2340 × Astro Boy

Introducing 2340’s first cultural crossover. From Metro City to Le Noirmont. A watch that speaks across generations.

First partnership of its kind and a meaningful one. The Louis Erard x Astro Boy marks the moment 2340 steps into cultural territory, through an icon that shaped the childhood of Manuel Emch and generations of fans around the world: Astro Boy. Behind the pop visuals, a deeper narrative. Astro Boy is more than just a hero. He’s a symbol of coexistence, empathy and resistance against discrimination, between humans, machines and everything in between. A hopeful view of a future that feels more relevant than ever. Only 178 timepieces for this “soulfull” collector’s item.

This is the first step in a long-term creative direction: working with cultural references that shaped our generation. The 2340 takes flight with a childhood icon: Astro Boy who left a mark on me, like he did on many others. I’m interested in creators and stories that matter , both emotionally and culturally. The 2340 is more than a new face, it’s a canvas. A platform to bring these references to life. Astro Boy is the first. There will be more: video games, cult icons, everything that shaped our collective memory.Manuel Emch

Watch facts that matter

  • A cultural first: the first-ever Louis Erard watch to feature a pop culture collaboration.

  • A 178-piece edition: limited production, no restock, made for collectors.

  • Layered dial: Astroboy is fully applied on the dial, not printed, with layered volumes and depth that create a sense of motion.

  • Original Tezuka artwork: created with Tezuka Productions, based on early classic Astroboy illustrations.

  • A tribute in steel and titanium: built on the 2340 line, Louis Erard’s new sports watch integrated architecture.

  • More than a watch: a timepiece about identity and the future we want to live in.

Astro Boy: a pop culture legend

From 1952 to today, created by the father of manga Osamu Tezuka, Astro Boy is a global pop culture legend. This little android was born from grief, built to replace a lost child and ended up fighting injustice with heart and humanity. A paradox: a robot more human than many humans. Astro Boy has become a worldwide symbol of hope, humanity and coexistence. For this special edition, Louis Erard partnered with Tezuka Productions, obtaining rights to use original illustrations from the classic Astro Boy series. Carefully adapted, layered and sculpted, Astro Boy is not printed on the dial: he’s applied, in volume, with a dynamic trail of smoke and motion that brings him to life. Behind him looms one of the series’ famous villains, subtly rendered in black. Between the two: Metro City, vertically satin-finished and deeply engraved into the dial. The caseback features a custom engraving. A tribute to Astro’s legacy and the future he fought for.

2340: a new platform of expression

The Astro Boy special edition is built on the foundation of Louis Erard’s newly launched 2340 collection: the first integrated-bracelet series in the brand’s history. It keeps its distinctive hybrid case with a brushed titanium body and polished steel crown, bezel and lugs; a slim profile at just 8.95 mm thick; as well as an integrated bi-material titanium & steel bracelet with brushed and polished finishes, developed over three years. The 2340 collection is a design and engineering milestone for Louis Erard and the new foundation for creative exploration at Louis Erard.

How Astro Boy powers up the 2340

No indexes. No clutter. Just a story. This special edition reimagines the dial as a cinematic stage, where Astro Boy takes flight. From 6 to 12 o’clock, the dial is engraved with a Metro City backdrop with a vertical satin-brushed finish. The design builds depth through a multi-layered construction. Astro Boy, in full color, bursts from the dial with his smoke trail and cloud behind him; a stealthy black villain looms in the background, while a raised circular rehaut frames the scene, printed with a white minutes track and lit with a Super-LumiNova® SLN-C1 blue glow. The layered dial construction features three applied elements: Astro Boy, the villain and the rehaut inner flange, plus a two-level engraved main dial for added dimension and texture.
