What is the Louis Erard x Astro Boy watch?
It is Louis Erard’s 2340 collaboration with Tezuka Productions, reference 35123TA23.BMT12. Louis Erard lists the edition at 178 pieces. Its official product page also says it is not available for sale in Hong Kong, China, or Macao; that restriction applies to the territories named on the listing, not necessarily to every sales channel.

The collaboration turns the watch’s dial into a small scene rather than a simple character portrait. Osawa Shokai, the Japanese distributor, describes Astro Boy flying across a vertically satin-brushed “future city,” with Brando in the background. Louis Erard calls the setting a “Metro City” motif: applied robot figures sit above an engraved or stamped city pattern and a chapter ring with a white minute track. The brand describes Brando’s applique with a black “LE” emblem and Astro Boy’s with coloured pad printing.
Osawa Shokai frames Astro Boy as a character associated with coexistence, empathy, and resistance to discrimination, and says the edition uses original illustrations through the Tezuka Productions partnership. That is the distributor’s interpretation of the collaboration’s themes.

The 5-bar rating is a stated specification, not a recommendation for a particular water activity. The available product descriptions establish the dial’s construction and materials, but do not establish how easy it is to read in everyday use.

The collaboration is built into the composition: the figures are applied above a city-scene dial, giving Astro Boy and Brando separate visual depth from the background. The white minute track forms a chapter ring around that scene, while the mixed titanium-and-steel construction carries the watch’s two-material design from case to integrated bracelet. The published descriptions specify those elements without making claims about real-world wrist feel or performance.
