Mushoku Tensei Reveals New Official Smartwatch Collection Starring Rudeus, Sylphiette, Roxy and Eris

Mushoku Tensei: Jobless Reincarnation is getting a new collection of official smartwatches, with four designs based on Rudeus, Sylphiette, Roxy and Eris that change their character artwork as you walk.

Created by Japanese character collaboration brand GARRACK, each model combines a character-themed strap with an original digital watch face containing several references to the anime.

GARRACK has previously created official watch collections for a growing number of major anime series, including ONE PIECE, Haikyu!! and Chainsaw Man, often incorporating character-specific artwork and interactive features directly into the watches.

Mushoku Tensei follows Rudeus Greyrat after he is reincarnated into a fantasy world with the memories of his previous life intact, giving him another chance to build relationships and make different choices while developing his abilities as a magician.

The anime’s third season began airing in July 2026, continuing Rudeus’ story while bringing characters such as Eris back into focus after several years of growth and training.

That progression has been incorporated directly into the new watches, with the character shown on each watch face changing as the wearer accumulates steps throughout the day, moving through appearances based on the anime’s first, second, and third seasons.

The artwork changes at different step milestones before resetting once the wearer reaches 10,000 steps, effectively turning everyday movement into a visual representation of each character’s development across the series.

Battery life has also been worked into the designs, with weapons and magical effects changing depending on how much charge remains.

Rudeus’ model changes the effects surrounding Aqua Heartia as its battery drains, while incoming notifications are represented by an icon based on his diary and a shortcut provides quick access to workout tracking.

Sylphiette’s version changes the magical effects around her staff and uses her pendant as its notification icon, while a shortcut to breathing exercises references her use of healing magic.

Roxy receives a similar changing staff effect, but her version includes a shortcut to the weather function in reference to her use of rain and lightning magic, with her pendant appearing when notifications arrive.

Eris’ watch changes the appearance of her sword according to the remaining battery level, adds a workout shortcut inspired by her intense training and uses the letter she wrote to Rudeus as its notification icon.

All four models are built around the HUAWEI Band 11, which GARRACK has also used for other recent anime smartwatch collaborations including its SPY×FAMILY collection featuring Loid, Anya, Yor and Bond.

The watch body weighs approximately 16g without its strap, while fast charging provides around two days of use from a five-minute charge and a full battery can last for up to 14 days.

Fitness and health features include heart-rate and stress monitoring, sleep tracking, blood oxygen measurement and more than 100 workout modes, with additional functions covering music controls, weather, notifications, timers and a remote camera shutter.

Each watch also comes with a black replacement strap for more understated everyday use and is packaged inside a special box featuring its respective Mushoku Tensei character.

Pre-orders for the “Mushoku Tensei: Jobless Reincarnation x GARRACK” collection will open on September 25 through GARRACK’s World Wide Watch store, with each smartwatch priced at ¥10,890 (approximately $69 / £52) ahead of their October 23, 2026 release.
